1I.e. either descendant of, or from the same district as, Omri (see Hogg,Ency. Bib.col. 2291). The Assyrian king’s sculpture, depicting the embassy and its gifts, is the so-called “black obelisk” now in the British Museum (Nimroud Central Gallery, No. 98;Guide to Bab. and Ass. Antiq., 1900, p. 24 seq., pl. ii.).

JEKYLL, SIR JOSEPH(1663-1738), English lawyer and master of the rolls, son of John Jekyll, was born in London, and after studying at the Middle Temple was called to the bar in 1687. He rapidly rose to be chief justice of Chester (1697), serjeant-at-law and king’s serjeant (1700), and a knight. In 1717 he was made master of the rolls. A Whig in politics, he sat in parliament for various constituencies from 1697 to the end of his life, and took an active part there in debating constitutional questions with much learning, though, according to Lord Hervey (Mem.1, 474), with little “approbation.” He was censured by the House of Commons for accepting a brief for the defence of Lord Halifax in a prosecution ordered by the house. He was one of the managers of the impeachment of the Jacobite earl of Wintoun in 1715, and of Harley (Lord Oxford) in 1717. In later years he supported Walpole. He became very unpopular in 1736 for his introduction of the “gin act,” taxing the retailing of spirituous liquors, and his house had to be protected from the mob. Pope has an illusion to “Jekyll or some odd Whig, Who never changed his principle or wig” (Epilogue to the Satires). Jekyll was also responsible for the Mortmain Act of 1736, which was not superseded till 1888. He died without issue in 1738.

His great-nephewJoseph Jekyll(d. 1837) was a lawyer, politician and wit, who excited a good deal of contemporary satire, and who wrote somejeux d’espritwhich were well-known in his time. HisLetters of the late Ignatius Sancho, an African, was published in 1782. In 1894 his correspondence was edited, with a memoir, by the Hon. Algernon Bourke.

JELLACHICH, JOSEF,Count(1801-1859), Croatian statesman, was born on the 16th of October 1801 at Pétervárad. He entered the Austrian army (1819), fought against the Bosnians in 1845, was made ban of Croatia, Slavonia and Dalmatia in 1848 on the petition of the Croatians, and was simultaneously raised to the rank of lieutenant-general by the emperor. As ban, Jellachich’s policy was directed to preserving the Slav kingdoms for the Habsburg monarchy by identifying himself with the nationalist opposition to Magyar ascendancy, while at the same time discouraging the extreme “Illyrism” advocated by Lodovik Gáj (1809-1872). Though his separatist measures at first brought him into disfavour at the imperial court, their true objective was soon recognized, and, with the triumph of the more violent elements of the Hungarian revolution, he was hailed as the most conspicuous champion of the unity of the empire, and was able to bring about that union of the imperial army with the southern Slavs by which the revolution in Vienna and Budapest was overthrown (seeAustria-Hungary:History). He began the war of independence in September 1848 by crossing the Drave at the head of 40,000 Croats. After the bloody battle of Buda he concluded a three days’ truce with the Hungarians to enable him to assist Prince Windischgrätz to reduce Vienna, and subsequently fought against the Magyars at Schwechát. During the winter campaign of 1848-49 he commanded, under Windischgrätz, the Austrian right wing, capturing Magyar-Ovar and Raab, and defeating the Magyars at Mór. After the recapture of Buda he was made commander-in-chief of the southern army.At first he gained some successes against Bem (q.v.), but on the 14th of July 1849 was routed by the Hungarians at Hegyes and driven behind the Danube. He took no part in the remainder of the war, but returned to Agram to administer Croatia. In 1853 he was appointed commander-in-chief of the army sent against Montenegro, and in 1855 was created a count. He died on the 20th of May 1859. HisGedichtewere published at Vienna in 1851.

JELLINEK, ADOLF(1821-1893), Jewish preacher and scholar, was born in Moravia. After filling clerical posts in Leipzig, he becamePrediger(preacher) in Vienna in 1856. He was associated with the promoters of the New Learning within Judaism, and wrote on the history of the Kabbala. His bibliographies (each bearing the Hebrew titleQontres) were useful compilations. But his most important work lay in three other directions. (1)Midrashic.Jellinek published in the six parts of hisBeth ha-Midrasch(1853-1878) a large number of smallerMidrashi, ancient and medieval homilies and folk-lore records, which have been of much service in the recent revival of interest in Jewish apocalyptic literature. A translation of these collections of Jellinek into German was undertaken by A. Wuensche, under the general titleAus Israels Lehrhalle. (2)Psychological.Before the study of ethnic psychology had become a science, Jellinek devoted attention to the subject. There is much keen analysis and original investigation in his two essaysDer jüdische Stamm(1869) andDer jüdische Stamm in nicht-jüdischen Sprüch-wörtern(1881-1882). It is to Jellinek that we owe the oft-repeated comparison of the Jewish temperament to that of women in its quickness of perception, versatility and sensibility. (3)Homiletic.Jellinek was probably the greatest synagogue orator of the 19th century. He published some 200 sermons, in most of which are displayed unobtrusive learning, fresh application of old sayings, and a high conception of Judaism and its claims. Jellinek was a powerful apologist and an accomplished homilist, at once profound and ingenious.

His son,George Jellinek, was appointed professor of international law at Heidelberg in 1891. Another son,Max Hermann Jellinek, was made assistant professor of philology at Vienna in 1892.

A brother of Adolf,Hermann Jellinek(b. 1823), was executed at the age of 26 on account of his association with the Hungarian national movement of 1848. One of Hermann Jellinek’s best-known works wasUriel Acosta. Another brother,Moritz Jellinek(1823-1883), was an accomplished economist, and contributed to the Academy of Sciences essays on the price of cereals and on the statistical organization of the country. He founded the Budapest tramway company (1864) and was also president of the corn exchange.

JEMAPPES,a town in the province of Hainaut, Belgium, near Mons, famous as the scene of the battle at which Dumouriez, at the head of the French Revolutionary Army, defeated the Austrian army (which was greatly outnumbered) under the duke of Saxe-Teschen and Clerfayt on the 6th of November 1792 (seeFrench Revolutionary Wars).

JENA,a university town of Germany, in the grand duchy of Saxe-Weimar, on the left bank of the Saale, 56 m. S.W. from Leipzig by the Grossberigen-Saalfeld and 12 m. S.E. of Weimar by the Weimar-Gera lines of railway. Pop. (1905), 26,355. Its situation in a broad valley environed by limestone hills is somewhat dreary. To the north lies the plateau, descending steeply to the valley, famous as the scene of the battle of Jena. The town is surrounded by promenades occupying the site of the old fortifications; it contains in addition to the medieval market square, many old-fashioned houses and quaint narrow streets. Besides the old university buildings, the most interesting edifices are the 15th-century church of St Michael, with a tower 318 ft. high, containing an altar, beneath which is a doorway leading to a vault, and a bronze statue of Luther, originally destined for his tomb; the university library, in which is preserved a curious figure of a dragon; and the bridge across the Saale, as long as the church steeple is high, the centre arch of which is surmounted by a stone carved head of a malefactor. Across the river is the “mountain,” or hill, whence a fine view is obtained of the town and surroundings, and hard by the Fuchs-Turm (Fox tower) celebrated for student orgies, while in the centre of the town is the house of an astronomer, Weigel, with a deep shaft through which the stars can be seen in the day time. Thus the seven marvels of Jena are summed up in the Latin lines:—

Ara, caput, draco, mons, pons, vulpecula turris,Weigeliana domus; septem miracula Jenae.

Ara, caput, draco, mons, pons, vulpecula turris,

Weigeliana domus; septem miracula Jenae.

There must also be mentioned the university church, the new university buildings, which occupy the site of the ducal palace (Schloss) where Goethe wrote hisHermann und Dorothea, the Schwarzer Bär Hotel, where Luther spent the night after his flight from the Wartburg, and four towers and a gateway which now alone mark the position of the ancient walls. The town has of late years become a favourite residential resort and has greatly extended towards the west, where there is a colony of pleasant villas. Its chief prosperity centres, however, in the university. In 1547 the elector John Frederick the Magnanimous of Saxony, while a captive in the hands of the emperor Charles V., conceived the plan of founding a university at Jena, which was accordingly established by his three sons. After having obtained a charter from the emperor Ferdinand I., it was inaugurated on the 2nd of February 1558. It was most numerously attended about the middle of the 18th century; but the most brilliant professoriate was under the duke Charles Augustus, Goethe’s patron (1787-1806), when Fichte, Hegel, Schelling, Schlegel and Schiller were on its teaching staff. Founded as a home for the new religious opinions of the 16th century, it has ever been in the forefront of German universities in liberally accepting new ideas. It distances perhaps every other German university in the extent to which it carries out what are popularly regarded as the characteristics of German student-life—duelling and the passion forFreiheit. At the end of the 18th and the beginning of the 19th century, the opening of new universities, co-operating with the suspicions of the various German governments as to the democratic opinions which obtained at Jena, militated against the university, which has never regained its former prosperity. In 1905 it was attended by about 1100 students, and its teaching staff (includingprivatdocenten) numbered 112. Amongst its numerous auxiliaries may be mentioned the library, with 200,000 volumes, the observatory, the meteorological institute, the botanical garden, seminaries of theology, philology and education, and well equipped clinical, anatomical and physical institutes. There are also veterinary and agricultural colleges in connexion with the university. The manufactures of Jena are not considerable. The book trade has of late years revived, and there are several printing establishments.

Jena appears to have possessed municipal rights in the 13th century. At the beginning of the 14th century it was in the possession of the margraves of Meissen, from whom it passed in 1423 to the elector of Saxony. Since 1485 it has remained in the Ernestine line of the house of Saxony. In 1662 it fell to Bernhard, youngest son of William duke of Weimar, and became the capital of a small separate duchy. Bernhard’s line having become extinct in 1690, Jena was united with Eisenach, and in 1741 reverted with that duchy to Weimar. In more modern times Jena has been made famous by the defeat inflicted in the vicinity, on the 14th of October 1806, by Napoleon upon the Prussian army under the prince of Hohenlohe (seeNapoleonic Campaigns).

JENATSCH, GEORG(1596-1639), Swiss political leader, one of the most striking figures in the troubled history of the Grisons in the 17th century, was born at Samaden (capital of the Upper Engadine). He studied at Zürich and Basel, and in 1617 became the Protestant pastor of Scharans (near Thusis). But almost at once he plunged into active politics, taking the side of the Venetian and Protestant party of the Salis family, as against the Spanish and Romanist policy supported by the rival family, that of Planta. He headed the “preachers” who in 1618 tortured to death the arch-priest Rusca, of Sondrio, and outlawed the Plantas. As reprisals, a number of Protestants were massacred at Tirano (1620), in the Valtellina, a very fertile valley, of considerable strategical importance (for through it the Spaniards in Milan could communicate by the Umbrail Pass with the Austrians in Tirol), which then fell into the hands of the Spanish. Jenatsch took part in the murder (1621) of Pompey Planta, the head of the rival party, but later with his friends was compelled to fly the country, giving up his position as a pastor, and henceforth acting solely as a soldier. He helped in the revolt against the Austrians in the Prättigau (1622), and in the invasion of the Valtellina by a French army (1624), but the peace made (1626) between France and Spain left the Valtellina in the hands of the pope, and so destroyed Jenatsch’s hopes. Having killed his colonel, Ruinelli, in a duel, Jenatsch had once more to leave his native land, and took service with the Venetians (1629-1630). In 1631 he went to Paris, and actively supported Richelieu’s schemes for driving the Spaniards out of the Valtellina, which led to the successful campaign of Rohan (1635), one of whose firmest supporters was Jenatsch. But he soon saw that the French were as unwilling as the Spaniards to restore the Valtellina to the Grisons (which had seized it in 1512). So he became a Romanist (1635), and negotiated secretly with the Spaniards and Austrians. He was the leader of the conspiracy which broke out in 1637, and resulted in the expulsion of Rohan and the French from the Grisons. This treachery on Jenatsch’s part did not, however, lead to the freeing of the Valtellina from the Spaniards, and once more he tried to get French support. But on the 24th of January 1639 he was assassinated at Coire by the Plantas; later in the same year the much coveted valley was restored by Spain to the Grisons, which held it till 1797. Jenatsch’s career is of general historical importance by reason of the long conflict between France and Spain for the possession of the Valtellina, which forms one of the most bloody episodes in the Thirty Years’ War.

JENGHIZ KHAN(1162-1227), Mongol emperor, was born in a tent on the banks of the river Onon. His father Yesukai was absent at the time of his birth, in a campaign against a Tatar chieftain named Temuchin. The fortune of war favoured Yesukai, who having slain his enemy returned to his encampment in triumph. Here he was met by the news that his wife Yulun had given birth to a son. On examining the childheobserved in its clenched fist a clot of coagulated blood like a red stone. In the eyes of the superstitious Mongol this circumstance referred to his victory over the Tatar chieftain, and he therefore named the infant Temuchin. The death of Yesukai, which placed Temuchin at the age of thirteen on the Mongol throne, was the signal also for the dispersal of several tribes whose allegiance the old chieftain had retained by his iron rule. When remonstrated with by Temuchin, the rebels replied: “The deepest wells are sometimes dry, and the hardest stone is sometimes broken; why should we cling to thee?” But Yulun was by no means willing to see her son’s power melt away; she led those retainers who remained faithful against the deserters, and succeeded in bringing back fully one half to their allegiance. With this doubtful material, Temuchin succeeded in holding his ground against the plots and open hostilities of the neighbouring tribes, more especially of the Naimans, Keraits and Merkits. With one or other of these he maintained an almost unceasing warfare until 1206, when he felt strong enough to proclaim himself the ruler of an empire. He therefore summoned the notables of his kingdom to an assembly on the banks of the Onon, and at their unanimous request adopted the name and title of Jenghiz Khan (Chinese, Chêng-sze, or “perfect warrior”). At this time there remained to him but one open enemy on the Mongolian steppes, Polo the Naiman khan. Against this chief he now led his troops, and in one battle so completely shattered his forces that Kushlek, the successor of Polo, who was left dead upon the field, fled with his ally Toto, the Merkit khan, to the river Irtysh.

Jenghiz Khan now meditated an invasion of the empire of the Kin Tatars, who had wrested northern China from the Sung dynasty. As a first step he invaded western Hia, and, having captured several strongholds, retired in the summer of 1208 to Lung-ting to escape the great heat of the plains. While there news reached him that Toto and Kushlek were preparing for war. In a pitched battle on the river Irtysh he overthrew them completely. Toto was amongst the slain, and Kushlek fled for refuge to the Khitan Tatars. Satisfied with his victory, Jenghiz again directed his forces against Hia. After having defeated the Kin army under the leadership of a son of the sovereign, he captured the Wu-liang-hai Pass in the Great Wall, and penetrated as far as Ning-sia Fu in Kansuh. With unceasing vigour he pushed on his troops, and even established his sway over the province of Liaotung. Several of the Kin commanders, seeing how persistently victory attended his banners, deserted to him, and garrisons surrendered at his bidding. Having thus secured a firm footing within the Great Wall, he despatched three armies in the autumn of 1213 to overrun the empire. The right wing, under his three sons, Juji, Jagatai and Ogotai, marched towards the south; the left wing, under his brothers Hochar, Kwang-tsin Noyen and Chow-tse-te-po-shi, advanced eastward towards the sea; while Jenghiz and his son Tulē with the centre directed their course in a south-easterly direction. Complete success attended all three expeditions. The right wing advanced as far as Honan, and after having captured upwards of twenty-eight cities rejoined headquarters by the great western road. Hochar made himself master of the country as far as Liao-si; and Jenghiz ceased his triumphal career only when he reached the cliffs of the Shantung promontory. But either because he was weary of the strife, or because it was necessary to revisit his Mongolian empire, he sent an envoy to the Kin emperor in the spring of the following year (1214), saying, “All your possessions in Shantung and the whole country north of the Yellow River are now mine with the solitary exception of Yenking (the modern Peking). By the decree of heaven you are now as weak as I am strong, but I am willing to retire from my conquests; as a condition of my doing so, however, it will be necessary that you distribute largess to my officers and men to appease their fierce hostility.” These terms of safety the Kin emperor eagerly accepted, and as a peace offering he presented Jenghiz with a daughter of the late emperor, another princess of the imperial house, 500 youths and maidens, and 3000 horses. No sooner, however, had Jenghiz passed beyond the Great Wall than the Kin emperor, fearing to remain any longer so near the Mongol frontier, moved his court to K’ai-fêng Fu in Honan. This transfer of capital appearing to Jenghiz to indicate a hostile attitude, he once more marched his troops into the doomed empire.

While Jenghiz was thus adding city to city and province to province in China, Kushlek, the fugitive Naiman chief, was not idle. With characteristic treachery he requested permission from his host, the Khitan khan, to collect the fragments of his army which had been scattered by Jenghiz at the battle on the Irtysh, and thus having collected a considerable force he leagued himself with Mahommed, the shah of Khwārizm, against the confiding khan. After a short but decisive campaign the allies remained masters of the position, and the khan was compelled to abdicate the throne in favour of the late guest.

With the power and prestige thus acquired, Kushlek prepared once again to measure swords with the Mongol chief. On receiving the news of his hostile preparations, Jenghiz at once took the field, and in the first battle routed the Naiman troops and made Kushlek a prisoner. His ill-gotten kingdom becamean apanage of the Mongol Empire. Jenghiz now held sway up to the Khwārizm frontier. Beyond this he had no immediate desire to go, and he therefore sent envoys to Mahommed, the shah, with presents, saying, “I send thee greeting; I know thy power and the vast extent of thine empire; I regard thee as my most cherished son. On my part thou must know that I have conquered China and all the Turkish nations north of it; thou knowest that my country is a magazine of warriors, a mine of silver, and that I have no need of other lands. I take it that we have an equal interest in encouraging trade between our subjects.” This peaceful message was well received by the shah, and in all probability the Mongol armies would never have appeared in Europe but for an unfortunate occurrence. Shortly after the despatch of this first mission Jenghiz sent a party of traders into Transoxiana who were seized and put to death as spies by Inaljuk, the governor of Otrar. As satisfaction for this outrage Jenghiz demanded the extradition of the offending governor. Far from yielding to this summons, however, Mahommed beheaded the chief of the Mongol envoys, and sent the others back without their beards. This insult made war inevitable, and in the spring of 1219 Jenghiz set out from Karakorum on a campaign which was destined to be as startling in its immediate results as its ulterior effects were far-reaching. The invading force was in the first instance divided into two armies: one commanded by Jenghiz’s second son Jagatai was directed to march against the Kankalis, the northern defenders of the Khwārizm empire; and the other, led by Juji, his eldest son, advanced by way of Sighnak against Jand (Jend). Against this latter force Mahommed led an army of 400,000 men, who were completely routed, leaving it is said 160,000 dead upon the field. With the remnant of his host Mahommed fled to Samarkand. Meanwhile Jagatai marched down upon the Syr Daria (Jaxartes) by the pass of Taras and invested Otrar, the offending city. After a siege of five months the citadel was taken by assault, and Inaljuk and his followers were put to the sword. The conquerors levelled the walls with the ground, after having given the city over to pillage. At the same time a third army besieged and took Khojent on the Jaxartes; and yet a fourth, led by Jenghiz and his youngest son Tulē, advanced in the direction of Bokhara. Tashkent and Nur surrendered on their approach, and after a short siege Bokhara fell into their hands. On entering the town Jenghiz ascended the steps of the principal mosque, and shouted to his followers, “The hay is cut; give your horses fodder.” No second invitation to plunder was needed; the city was sacked, and the inhabitants either escaped beyond the walls or were compelled to submit to infamies which were worse than death. As a final act of vengeance the town was fired, and before the last of the Mongols left the district, the great mosque and certain palaces were the only buildings left to mark the spot where the “centre of science” once stood. From the ruins of Bokhara Jenghiz advanced along the valley of the Sogd to Samarkand, which, weakened by treachery, surrendered to him, as did also Balkh. But in neither case did submission save either the inhabitants from slaughter or the city from pillage. Beyond this point Jenghiz went no farther westward, but sent Tulē, at the head of 70,000 men, to ravage Khorasan, and two flying columns under Chēpē and Sabutai Bahadar to pursue after Mahommed who had taken refuge in Nishapur. Defeated and almost alone, Mahommed fled before his pursuers to the village of Astara on the shore of the Caspian Sea, where he died of an attack of pleurisy, leaving his empire to his son Jelaleddīn (Jalāl ud-din). Meanwhile Tulē carried his arms into the fertile province of Khorasan, and after having captured Nessa by assault appeared before Merv. By an act of atrocious treachery the Mongols gained possession of the city, and, after their manner, sacked and burnt the town. From Merv Tulē marched upon Nishapur, where he met with a most determined resistance. For four days the garrison fought desperately on the walls and in the streets, but at length they were overpowered, and, with the exception of 400 artisans who were sent into Mongolia, every man, woman and child was slain. Herat escaped the fate which had overtaken Merv and Nishapur by opening its gates to the Mongols. At this point of his victorious career Tulē received an order to join Jenghiz before Talikhan in Badakshan, where that chieftain was preparing to renew his pursuit of Jelaleddīn, after a check he had sustained in an engagement fought before Ghazni. As soon as sufficient reinforcements arrived Jenghiz advanced against Jelaleddīn, who had taken up a position on the banks of the Indus. Here the Turks, though far outnumbered, defended their ground with undaunted courage, until, beaten at all points, they fled in confusion. Jelaleddīn, seeing that all was lost, mounted a fresh horse and jumped into the river, which flowed 20 ft. below. With admiring gaze Jenghiz watched the desperate venture of his enemy, and even saw without regret the dripping horseman mount the opposite bank. From the Indus Jenghiz sent in pursuit of Jelaleddīn, who fled to Delhi, but failing to capture the fugitive the Mongols returned to Ghazni after having ravaged the provinces of Lahore, Peshawar and Melikpur. At this moment news reached Jenghiz that the inhabitants of Herat had deposed the governor whom Tulē had appointed over the city, and had placed one of their own choice in his room. To punish this act of rebellion Jenghiz sent an army of 80,000 men against the offending city, which after a siege of six months was taken by assault. For a whole week the Mongols ceased not to kill, burn and destroy, and 1,600,000 persons are said to have been massacred within the walls. Having consummated this act of vengeance, Jenghiz returned to Mongolia by way of Balkh, Bokhara and Samarkand.

Meanwhile Chēpē and Sabutai marched through Azerbeijan, and in the spring of 1222 advanced into Georgia. Here they defeated a combined force of Lesghians, Circassians and Kipchaks, and after taking Astrakhan followed the retreating Kipchaks to the Don. The news of the approach of the mysterious enemy of whose name even they were ignorant was received by the Russian princes at Kiev with dismay. At the instigation, however, of Mitislaf, prince of Galicia, they assembled an opposing force on the Dnieper. Here they received envoys from the Mongol camp, whom they barbarously put to death. “You have killed our envoys,” was the answer made by the Mongols; “well, as you wish for war you shall have it. We have done you no harm. God is impartial; He will decide our quarrel.” In the first battle, on the river Kaleza, the Russians were utterly routed, and fled before the invaders, who, after ravaging Great Bulgaria retired, gorged with booty, through the country of Saksin, along the river Aktuba, on their way to Mongolia.

In China the same success had attended the Mongol arms as in western Asia. The whole of the country north of the Yellow river, with the exception of one or two cities, was added to the Mongol rule, and, on the death of the Kin emperor Süan Tsung in 1223, the Kin empire virtually ceased to be, and Jenghiz’s frontiers thus became conterminous with those of the Sung emperors who held sway over the whole of central and southern China. After his return from Central Asia, Jenghiz once more took the field in western China. While on this campaign the five planets appeared in a certain conjunction, which to the superstitiously minded Mongol chief foretold that evil was awaiting him. With this presentiment strongly impressed upon him he turned his face homewards, and had advanced no farther than the Si-Kiang river in Kansuh when he was seized with an illness of which he died a short time afterwards (1227) at his travelling palace at Ha-lao-tu, on the banks of the river Sale in Mongolia. By the terms of his will Ogotai was appointed his successor, but so essential was it considered to be that his death should remain a secret until Ogotai was proclaimed that, as the funeral procession moved northwards to the great ordu on the banks of the Kerulen, the escort killed every one they met. The body of Jenghiz was then carried successively to the ordus of his several wives, and was finally laid to rest in the valley of Kilien.

Thus ended the career of one of the greatest conquerors the world has ever seen. Born and nurtured as the chief of a petty Mongolian tribe, he lived to see his armies victorious from the China Sea to the banks of the Dnieper; and, though the empirewhich he created ultimately dwindled away under the hands of his degenerate descendants, leaving not a wrack behind, we have in the presence of the Turks in Europe a consequence of his rule, since it was the advance of his armies which drove their Osmanli ancestors from their original home in northern Asia, and thus led to their invasion of Bithynia under Othman, and finally their advance into Europe under Amurath I.

JENKIN, HENRY CHARLES FLEEMING(1833-1885), British engineer, was born near Dungeness on the 25th of March 1833, his father (d. 1885) being a naval commander, and his mother (d. 1885) a novelist of some literary repute, her best books perhaps beingCousin Stella(1859) andWho breaks, pays(1861). Fleeming Jenkin was educated at first in Scotland, but in 1846 the family went to live abroad, owing to financial straits, and he studied at Genoa University, where he took a first-class degree in physical science. In 1851 he began his engineering career as apprentice in an establishment at Manchester, and subsequently he entered Newall’s submarine cable works at Birkenhead. In 1859 he began, in concert with Sir William Thomson (afterwards Lord Kelvin), to work on problems respecting the making and use of cables, and the importance of his researches on the resistance of gutta-percha was at once recognized. From this time he was in constant request in connexion with submarine telegraphy, and he became known also as an inventor. In partnership with Thomson, he made a large income as a consulting telegraph engineer. In 1865 he was elected F.R.S., and was appointed professor of engineering at University College, London. In 1868 he obtained the same professorship at Edinburgh University, and in 1873 he published a textbook ofMagnetism and Electricity, full of original work. He was author of the article “Bridges” in the ninth edition of this encyclopaedia. His influence among the Edinburgh students was pronounced, and R. L. Stevenson’s well-knownMemoiris a sympathetic tribute to his ability and character. The meteoric charm of his conversation is well described in Stevenson’s essay on “Talk and Talkers,” under the name of Cockshot. Jenkin’s interests were by no means confined to engineering, but extended to the arts and literature; his miscellaneous papers, showing his critical and unconventional views, were issued posthumously in two volumes (1887). In 1882 Jenkin invented an automatic method of electric transport for goods—“telpherage”—but the completion of its details was prevented by his death on the 12th of June 1885. A telpher line on his system was subsequently erected at Glynde in Sussex. He was also well known as a sanitary reformer, and during the last ten years of his life he did much useful work in inculcating more enlightened ideas on the subject both in Edinburgh and other places.

JENKINS, SIR LEOLINE(1623-1685), English lawyer and diplomatist, was the son of a Welsh country gentleman. He was born in 1623 and was educated at Jesus College, Oxford, of which he was elected a fellow at the Restoration in 1660, having been an ardent royalist during the civil war and commonwealth; and in 1661 he became head of the college. In the same year he was made registrar of the consistory court of Westminster; in 1664 deputy judge of the court of arches; about a year later judge of the admiralty court; in 1689 judge of the prerogative court of Canterbury. In these offices Jenkins did enduring work in elucidating and establishing legal principles, especially in relation to international law and admiralty jurisdiction. He was selected to draw up the claim of Charles II. to succeed to the property of his mother, Henrietta Maria, on her death in August 1666, and while in Paris for this purpose he succeeded in defeating the rival claim of the duchess of Orleans, being rewarded by a knighthood on his return. In 1673, on being elected member for Hythe, Jenkins resigned the headship of Jesus College. He was one of the English representatives at the congress of Cologne in 1673, and at the more important congress of Nijmwegen in 1676-1679. He was made a privy councillor in February 1680 and became secretary of state in April of the same year, in which office he was the official leader of the opposition to the Exclusion Bill, though he was by no means a pliant tool in the hands of the court. He resigned office in 1684, and died on the 1st of September 1685. He left most of his property to Jesus College, Oxford, including his books, which he bequeathed to the college library, built by himself; and he left some important manuscripts to All Souls College, where they are preserved. Jenkins left his impress on the law of England in the Statute of Frauds, and the Statute of Distributions, of which he was the principal author, and of which the former profoundly affected the mercantile law of the country, while the latter regulated the inheritance of the personal property of intestates. He was never married.

JENKINS, ROBERT(fl.1731-1745), English master mariner, is known as the protagonist of the “Jenkins’s ear” incident, which, magnified in England by the press and the opposition, became a contributory cause of the war between England and Spain (1739). Bringing home the brig “Rebecca” from the West Indies in 1731, Jenkins was boarded by a Spanish guarda-costa, whose commander rifled the holds and cut off one of his ears. On arriving in England Jenkins stated his grievance to the king, and a report was furnished by the commander-in-chief in the West Indies confirming his account. At first the case created no great stir, but in 1738 he repeated his story with dramatic detail before a committee of the House of Commons, producing what purported to be the ear that had been cut off. Afterwards it was suggested that he might have lost the ear in the pillory.

Jenkins was subsequently given the command of a ship in the East India Company’s service, and later became supervisor of the company’s affairs at St Helena. In 1741 he was sent from England to that island to investigate charges of corruption brought against the acting governor, and from May 1741 until March 1742 he administered the affairs of the island. Thereafter he resumed his naval career, and is stated in an action with a pirate vessel to have preserved his own vessel and three others under his care (see T. H. Brooke,History of the Island of St Helena(London, 2nd ed., 1824), and H. R. Janisch,Extracts from the St Helena Records, 1885).

JENKS, JEREMIAH WHIPPLE(1856- ), American economist, was born in St Clair, Michigan, on the 2nd of September 1856. He graduated at the university of Michigan in 1878; taught Greek, Latin and German in Mt. Morris College, Illinois; studied in Germany, receiving the degree of Ph.D. from the university of Halle in 1885; taught political science and English literature at Knox College, Galesburg, Ill., in 1886-1889; was professor of political economy and social science at Indiana State University in 1889-1891; and was successively professor of political, municipal and social institutions (1891-1892), professor of political economy and civil and social institutions (1892-1901), and after 1901 professor of political economy and politics at Cornell University. In 1899-1901 he served as an expert agent of the United States industrial commission on investigation of trusts and industrial combinations in the United States and Europe, and contributed to vols. i., viii. and xiii. of this commission’s report (1900 and 1901), vol. viii. being a report, written wholly by him, on industrial combinations in Europe. In 1901-1902 he was special commissioner of the United States war department on colonial administration, and wrote aReport on Certain Economic Questions in the English and Dutch Colonies in the Orient, published (1902) by the bureau of insular affairs; and in 1903 he was adviser to the Mexican ministry of finance on projected currency changes. In 1903-1904 he was a member of the United States commission on international exchange, in especial charge of the reform of currency in China; in 1905 he was special representative of the United States with the imperial Chinese special mission visiting the United States. In 1907 he became a member of the United States immigration commission. Best known as an expert on “trusts,” he has written besides on elections, ballot reform, proportional representation, on education (especially as a training for citizenship), on legislation regarding highways, &c.

His principal published works areHenry C. Carey als Nationalökonom(Halle a. S., 1885);The Trust Problem(1900; revised 1903);Great Fortunes(1906);Citizenship and the Schools(1906); andPrinciples of Politics(1909).

JENNÉ,a city of West Africa, formerly the capital of the Songhoi empire, now included in the French colony of Upper Senegal and Niger. Jenné is situated on a marigot or natural canal connecting the Niger and its affluent the Bani or Mahel Balevel, and is within a few miles of the latter stream. It lies 250 m. S.W. of Timbuktu in a straight line. The city is surrounded by channels connected with the Bani but in the dry season it ceases to be an island. On the north is the Moorish quarter; on the north-west, the oldest part of the city, stood the citadel, converted by the French since 1893 into a modern fort. The market-place is midway between the fort and the commercial harbour. The old mosque, partially destroyed in 1830, covered a large area in the south-west portion of the city. It was built on the site of the ancient palace of the Songhoi kings. The architecture of many of the buildings bears a resemblance to Egyptian, the façades of the houses being adorned with great buttresses of pylonic form. There is little trace of the influence of Moorish or Arabian art. The buildings are mostly constructed of clay made into flat long bricks. Massive clay walls surround the city. The inhabitants are great traders and the principal merchants have representatives at Timbuktu and all the chief places on the Niger. The boats built at Jenné are famous throughout the western Sudan.

Jenné is believed to have been founded by the Songhoi in the 8th century, and though it has passed under the dominion of many races it has never been destroyed. Jenné seems to have been at the height of its power from the 12th to the 16th century, when its merchandise was found at every port along the west coast of Africa. From this circumstance it is conjectured that Jenné (Guinea) gave its name to the whole coast (seeGuinea). Subsequently, under the control of Moorish, Tuareg and Fula invaders, the importance of the city greatly declined. With the advent of the French, commerce again began to flourish.

See F. Dubois,Tombouctou la mystérieuse(Paris, 1897), in which several chapters are devoted to Jenné; alsoSonghoi;Timbuktu; andSenegal.

JENNER, EDWARD(1749-1823), English physician and discoverer of vaccination, was born at Berkeley, Gloucestershire, on the 17th of May 1749. His father, the Rev. Stephen Jenner, rector of Rockhampton and vicar of Berkeley, came of a family that had been long established in that county, and was possessed of considerable landed property; he died when Edward was only six years old, but his eldest son, the Rev. Stephen Jenner, brought his brother up with paternal care and tenderness. Edward received his early education at Wotton-under-Edge and Cirencester, where he already showed a strong taste for natural history. The medical profession having been selected for him, he began his studies under Daniel Ludlow, a surgeon of Sodbury near Bristol; but in his twenty-first year he proceeded to London, where he became a favourite pupil of John Hunter, in whose house he resided for two years. During this period he was employed by Sir Joseph Banks to arrange and prepare the valuable zoological specimens which he had brought back from Captain Cook’s first voyage in 1771. He must have acquitted himself satisfactorily in this task, since he was offered the post of naturalist in the second expedition, but declined it as well as other advantageous offers, preferring rather to practise his profession in his native place, and near his eldest brother, to whom he was much attached. He was the principal founder of a local medical society, to which he contributed several papers of marked ability, in one of which he apparently anticipated later discoveries concerning rheumatic inflammations of the heart. He maintained a correspondence with John Hunter, under whose direction he investigated various points in biology, particularly the hibernation of hedgehogs and habits of the cuckoo; his paper on the latter subject was laid by Hunter before the Royal Society, and appeared in thePhil. Trans.for 1788. He also devoted considerable attention to the varied geological character of the district in which he lived, and constructed the first balloon seen in those parts. He was a great favourite in general society, from his agreeable and instructive conversation, and the many accomplishments he possessed. Thus he was a fair musician, both as a part singer and as a performer on the violin and flute, and a very successful writer, after the fashion of that time, of fugitive pieces of verse. In 1788 he married Catherine Kingscote, and in 1792 he obtained the degree of doctor of medicine from St Andrews.

Meanwhile the discovery that is associated with his name had been slowly maturing in his mind. When only an apprentice at Sodbury, his attention had been directed to the relations between cow-pox and small-pox in connexion with a popular belief which he found current in Gloucestershire, as to the antagonism between these two diseases. During his stay in London he appears to have mentioned the thing repeatedly to Hunter, who, being engrossed by other important pursuits, was not so strongly persuaded as Jenner was of its possible importance, yet spoke of it to his friends and in his lectures. After he began practice in Berkeley, Jenner was always accustomed to inquire what his professional brethren thought of it; but he found that, when medical men had noticed the popular report at all, they supposed it to be based on imperfect induction. His first careful investigation of the subject dated from about 1775, and five years elapsed before he had succeeded in clearing away the most perplexing difficulties by which it was surrounded. He first satisfied himself that two different forms of disease had been hitherto confounded under the term cow-pox, only one of which protected against small-pox, and that many of the cases of failure were to be thus accounted for; and his next step was to ascertain that the true cow-pox itself only protects when communicated at a particular stage of the disease. At the same time he came to the conclusion that “the grease” of horses is the same disease as cow-pox and small-pox, each being modified by the organism in which it was developed. For many years, cow-pox being scarce in his county, he had no opportunity of inoculating the disease, and so putting his discovery to the test, but he did all he could in the way of collecting information and communicating what he had ascertained. Thus in 1788 he carried a drawing of the cow-pox, as seen on the hands of a milkmaid, to London, and showed it to Sir E. Home and others, who agreed that it was “an interesting and curious subject.” At length, on the 14th of May 1796, he was able to inoculate James Phipps, a boy about eight years old, with matter from cow-pox vesicles on the hand of Sarah Nelmes. On the 1st of the following July the boy was carefully inoculated with variolous matter, but (as Jenner had predicted) no small-pox followed. The discovery was now complete, but Jenner was unable to repeat his experiment until 1798, owing to the disappearance of cow-pox from the dairies. He then repeated his inoculations with the utmost care, and prepared a pamphlet (Inquiry into the Cause and Effects of the Variolae Vaccinae) which should announce his discovery to the world. Before publishing it, however, he thought it well to visit London, so as to demonstrate the truth of his assertions to his friends; but he remained in London nearly three months, without being able to find any person who would submit to be vaccinated. Soon after he had returned home, however, Henry Cline, surgeon of St Thomas’s Hospital, inoculated some vaccine matter obtained from him over the diseased hip-joint of a child, thinking the counter-irritation might be useful, and found the patient afterwards incapable of acquiring small-pox. In the autumn of the same year, Jenner met with the first opposition to vaccination; and this was the more formidable because itproceededfrom J. Ingenhousz, a celebrated physician and man of science. But meanwhile Cline’s advocacy of vaccination brought it much more decidedly before the medical profession, of whom the majority were prudent enough to suspend their judgment until they had more ample information. But besides these there were two noisy and troublesome factions, one of which opposed vaccination as a useless and dangerous practice, while the other endangered its success much more by rash and self-seeking advocacy. At the head of the latter was George Pearson,who in November 1798 published a pamphlet speculating upon the subject, before even seeing a case of cow-pox, and afterwards endeavoured, by lecturing on the subject and supplying the virus, to put himself forward as the chief agent in the cause. The matter which he distributed, which had been derived from cows that were found to be infected in London, was found frequently to produce, not the slight disease described by Jenner, but more or less severe eruptions resembling small-pox. Jenner concluded at once that this was due to an accidental contamination of the vaccine with variolous matter, and a visit to London in the spring of 1799 convinced him that this was the case. In the course of this year the practice of vaccination spread over England, being urged principally by non-professional persons of position; and towards its close attempts were made to found institutions for gratuitous vaccination and for supplying lymph to all who might apply for it. Pearson proposed to establish one of these in London, without Jenner’s knowledge, in which he offered him the post of honorary corresponding physician! On learning of this scheme to supplant him, and to carry on an institution for public vaccination on principles which he knew to be partly erroneous, Jenner once more visited London early in 1800, when he had influence enough to secure the abandonment of the project. He was afterwards presented to the king, the queen and the prince of Wales, whose encouragement materially aided the spread of vaccination in England. Meanwhile it had made rapid progress in the United States, where it was introduced by Benjamin Waterhouse, then professor of physic at Harvard, and on the continent of Europe, where it was at first diffused by De Carro of Vienna. In consequence of the war between England and France, the discovery was later in reaching Paris; but, its importance once realized, it spread rapidly over France, Spain and Italy.

A few of the incidents connected with its extension may be mentioned. Perhaps the most striking is the expedition which was sent out by the court of Spain in 1803, for the purpose of diffusing cow-pox through all the Spanish possessions in the Old and New Worlds, and which returned in three years, having circumnavigated the globe, and succeeded beyond its utmost expectations. Clergymen in Geneva and Holland urged vaccination upon their parishioners from the pulpit; in Sicily, South America and Naples religious processions were formed for the purpose of receiving it; the anniversary of Jenner’s birthday, or of the successful vaccination of James Phipps, was for many years celebrated as a feast in Germany; and the empress of Russia caused the first child operated upon to receive the name of Vaccinov, and to be educated at the public expense. About the close of the year 1801 Jenner’s friends in Gloucestershire presented him with a small service of plate as a testimonial of the esteem in which they held his discovery. This was intended merely as a preliminary to the presenting of a petition to parliament for a grant. The petition was presented in 1802, and was referred to a committee, of which the investigations resulted in a report in favour of the grant, and ultimately in a vote of £10,000.

Towards the end of 1802 steps were taken to form a society for the proper spread of vaccination in London, and the Royal Jennerian Society was finally established, Jenner returning to town to preside at the first meeting. This institution began very prosperously, more than twelve thousand persons having been inoculated in the first eighteen months, and with such effect that the deaths from small-pox, which for the latter half of the 18th century had averaged 2018 annually, fell in 1804 to 622. Unfortunately the chief resident inoculator soon set himself up as an authority opposed to Jenner, and this led to such dissensions as caused the society to die out in 1808.

Jenner was led, by the language of the chancellor of the exchequer when his grant was proposed, to attempt practice in London, but after a year’s trial he returned to Berkeley. His grant was not paid until 1804, and then, after the deduction of about £1000 for fees, it did little more than pay the expenses attendant upon his discovery. For he was so thoroughly known everywhere as the discoverer of vaccination that, as he himself said, he was “the vaccine clerk of the whole world.” At the same time he continued to vaccinate gratuitously all the poor who applied to him on certain days, so that he sometimes had as many as three hundred persons waiting at his door. Meanwhile honours began to shower upon him from abroad: he was elected a member of almost all the chief scientific societies on the continent of Europe, the first being that of Göttingen, where he was proposed by J. F. Blumenbach. But perhaps the most flattering proof of his influence was derived from France. On one occasion, when he was endeavouring to obtain the release of some of the unfortunate Englishmen who had been detained in France on the sudden termination of the Peace of Amiens, Napoleon was about to reject the petition, when Josephine uttered the name of Jenner. The emperor paused and exclaimed: “Ah, we can refuse nothing to that name.” Somewhat later he did the same service to Englishmen confined in Mexico and in Austria; and during the latter part of the great war persons before leaving England would sometimes obtain certificates signed by him which served as passports. In his own country his merits were less recognized. His applications on behalf of French prisoners in England were less successful; he never shared in any of the patronage at the disposal of the government, and was even unable to obtain a living for his nephew George.

In 1806 Lord Henry Petty (afterwards the marquess of Lansdowne) became chancellor of the exchequer, and was so convinced of the inadequacy of the former parliamentary grant that he proposed an address to the Crown, praying that the college of physicians should be directed to report upon the success of vaccination. Their report being strongly in its favour, the then chancellor of the exchequer (Spencer Perceval) proposed that a sum of £10,000 without any deductions should be paid to Jenner. The anti-vaccinationists found but one advocate in the House of Commons; and finally the sum was raised to £20,000. Jenner, however, at the same time had the mortification of learning that government did not intend to take any steps towards checking small-pox inoculation, which so persistently kept up that disease. About the same time a subscription for his benefit was begun in India, where his discovery had been gratefully received, but the full amount of this (£7383) only reached him in 1812.

The Royal Jennerian Society having failed, the national vaccine establishment was founded, for the extension of vaccination, in 1808. Jenner spent five months in London for the purpose of organizing it, but was then obliged, by the dangerous illness of one of his sons, to return to Berkeley. He had been appointed director of the institution; but he had no sooner left London than Sir Lucas Pepys, president of the college of physicians, neglected his recommendations, and formed the board out of the officials of that college and the college of surgeons. Jenner at once resigned his post as director, though he continued to give the benefit of his advice whenever it was needed, and this resignation was a bitter mortification to him. In 1810 his eldest son died, and Jenner’s grief at his loss, and his incessant labours, materially affected his health. In 1813 the university of Oxford conferred on him the degree of M.D. It was believed that this would lead to his election into the college of physicians, but that learned body decided that he could not be admitted until he had undergone an examination in classics. This Jenner at once refused; to brush up his classics would, he said, “be irksome beyond measure. I would not do it for a diadem. That indeed would be a bauble; I would not do it for John Hunter’s museum.”

He visited London for the last time in 1814, when he was presented to the Allied Sovereigns and to most of the principal personages who accompanied them. In the next year his wife’s death was the signal for him to retire from public life: he never left Berkeley again, except for a day or two, as long as he lived. He found sufficient occupation for the remainder of his life in collecting further evidence on some points connected with his great discovery, and in his engagements as a physician, a naturalist and a magistrate. In 1818 a severe epidemic of small-pox prevailed, and fresh doubts were thrown on theefficacy of vaccination, in part apparently owing to the bad quality of the vaccine lymph employed. This caused Jenner much annoyance, which was relieved by an able defence of the practice, written by Sir Gilbert Blane. But this led him, in 1821, to send a circular letter to most of the medical men in the kingdom inquiring into the effect of other skin diseases in modifying the progress of cow-pox. A year later he published his last work,On the Influence of Artificial Eruptions in Certain Diseases; and in 1823 he presented his last paper—“On the Migration of Birds”—to the Royal Society. On the 24th of January 1823 he retired to rest apparently as well as usual, and next morning rose and came down to his library, where he was found insensible on the floor, in a state of apoplexy, and with the right side paralysed. He never rallied, and died on the following morning.

A public subscription was set on foot, shortly after his death, by the medical men of his county, for the purpose of erecting some memorial in his honour, and with much difficulty a sufficient sum was raised to enable a statue to be placed in Gloucester Cathedral. In 1850 another attempt was made to set up a monument to him; this appears to have failed, but at length, in 1858, a statue of him was erected by public subscription in London.
