Chapter 12

[76]From the size of a femur and tibia ofÆpyornispreserved in the Paris Museum, it could not have been less in stature than the Dinornis elephantopus of New Zealand.

It will thus be seen that we have three distinct groups of giant land birds—the Moas, the Dromornis, and the Æpyornis,—occupying areas at present widely separated by the ocean.

This raises the difficult but very interesting question, how they got there; and the same applies to their living ancestors. The ostrich proper, Struthio camelus, inhabits Africa and Arabia; but there is evidence from history to show that it formerly existed in Beluchistan and Central Asia. And, going still further back, the geological record informs us that, in the Pliocene period, they inhabited what is now Northern India. In Australia we have the Cassowary (Casuarius) and the Emeu (Dromaius); in New Zealand, the Apteryx (or Kiwi). Now, as none of these birds can either fly or swim, it is impossible that they could have reached these regions separated as they now are; and it is hardly likely that they arose spontaneously in each district from totally different ancestors. But the new doctrine of evolution affords a key to the problem, and tells us that they all sprang from a common ancestor, of the struthious type (probably inhabiting the great northern continental area), and gradually migrated south along land areas now submerged. In this way we get some idea of the vast changes that have taken place in the geography of the world during later geological periods. Perhaps they were compelled to move south until they reached abodes free from carnivorous enemies. Having done so, they evidently flourished abundantly, especially in New Zealand, where there are so few mammals, except those recently introduced by man.

In North America Professor Cope has reported a large wingless fossil bird from the Eocene strata of New Mexico. In England we have two such—namely, the Dasornis, from the London Clay of Sheppey (Eocene period), and the Gastornis, from the Woolwich beds near Croydon, and from Paris (also Eocene).

It will thus be seen that big struthious birds have a long history, going far back into the Tertiary era, and that they once had a much wider geographical range than they have now. Doubtless, future discoveries will tend to fill up the gaps between all these various types, both living and extinct, and to connect them together in one chain of evolution.

The last great find of Moa-birds in New Zealand took place only last year, and was reported by a correspondent to theScotsman(November 13, 1891), writing from Oamaru. In the letter that appeared at the above date, our friend Mr. H. O. Forbes announces the discovery of an immense number of bones, estimated to represent at least five hundred Moas! They were found in the neighbourhood of Oamaru. And, after some preliminary remarks, he continues as follows:—

"The part of the field on which the remains were found bears no traces of any physical disturbance—e.g.of earthquake, or flood, or hurricane—that would account for the sudden destruction of a flock or ‘mob’ of Moas. The Moa, when alive, carried in its crop—like our own hens—a quantity of stones to serve as a private coffee-mill for digestive grinding; stones which, being somewhat in proportion to the magnitude of the giant bird, form, when found in one place, a ‘heap’ of stones which are easily identified as a Moa heap, and nothing else. And in the present case the heap was here and there found in such relation to the bones of an individual bird as to show that the Moa must have died on that spot, and remained there quietly undisturbed. Further, the number of birds represented by the exhumed remains is so great that the living birds could not have stood together on the space of ground on which the remains were found lying. Andthere is not on any of the bones any trace of such violence as must have left its mark if the death of the birds had been caused by a Moa-hunting mankind. Finally, it does not appear that in this particular district there ever has been, at any traceable period of the physical history of the land, a forest vegetation, such as might suggest that the catastrophe was caused by fire.

"The question how to account for the slaughter is raised likewise by two previous finds of Moa bones. The first of these, at Glenmark, in Canterbury, was the most memorable, because, being the first, it made the deepest impression. The second great find, far inland, up the Molineux River, otherwise the Clutha, was beneath the diluvium that is now worked by the gold-digger. The spot must have been the site of a lagoon, at one point of which there was a spring. Round about this point there were found the remains of, it was reckoned, five hundred individual Moas. The bones were quietlylaidthere, with, in some cases, the ‘heap’ of digestive stonesin situalong with the skeletons. And Mr. Booth, whose elaborate investigation of this case is recorded in the annual volume ofThe New Zealand Institute, suggested the theory that the climate of New Zealand was changing to a degree of cold intolerable to Moa nature; and that the birds, fleeing from its rigour, sought comfort in the spring of water, sheltering their featherless breast in it, and so dozing out of this troubled life. And in this new find the wonder comes back unmitigated, as a mystery unsolved. For here is no bog deep enough, as in the first instance, nor lagoon spring, as in the second, to account for that multitude of giant birds dying in one spot.

"Another curious puzzle is, on close inspection, found everywhere in the Moa bone discoveries. It is hardly possible to make sure that the bones of any one complete Moa skeleton all belong to the same individual I heard some one say the other day that it is not certain that any Moa in any earthly museum has all his own bones, and only his own.

“A main interest of such a find lies not in the power of supplying museums with specimens of what is rapidly disappearing from the face of the world, but in the possibility of finding species of Moa that have not hitherto been tabulated. Whether any new species have been brought to light on this occasion the experts will not say until there has been time to make a careful study of the bones, nor do they venture on any theory to account for there being so many individual birds dead in that one place, where there appears to be no room for the explanations offered in connection with previous great finds. The date of these birds appears to be earlier than that of the coming of the Maoris into New Zealand, say five or six hundred years ago, as the Maori memory appears to have in it no trace of feasting on these giant Moas, but celebrates the rat-hunt in its ancient heroic song. And your readers may picture their appearance by noticing the fact that one of the recently found bones must have belonged to a Moa fourteen feet high!”

Note.—For further information on this interesting subject, the reader is referred to a paper inNatural Science, October, 1892, by Mr. F. W. Hutton. In a valuable paper, read before the Royal Geographical Society by Mr. H. O. Forbes, March 13, 1893, the lecturer alluded to the important fact that bone belonging to big extinct struthious birds have been discovered in Patagonia. This is interesting news as bearing upon the theory of a former Antarctic continent connecting Australia and New Zealand with South Africa, and perhaps even with South America. After the lecture, to which we listened with great interest, the subject was discussed by Mr. Slater, Dr. Günther, and Dr. Henry Woodward. For ourselves we can see no great difficulty in accepting the theory that such a continent once existed, though it is out of harmony with the now rather fashionable theory of “the permanence of ocean basins”—a doctrine which seems to have been pressed too far.

CHAPTER XVI.

THE GREAT IRISH DEER AND STELLER’S SEA-COW.

“And, above all others, we should protect and hold sacred those types, Nature’s masterpieces, which are first singled out for destruction on account of their size, or splendour, or rarity, and that false detestable glory which is accorded to their most successful slayers. In ancient times the spirit of life shone brightest in these; and when others that shared the earth with them were taken by death they were left, being more worthy of perpetuation. Like immortal flowers they have drifted down to us on the ocean of time, and their strangeness and beauty bring to our imaginations a dream and a picture of that unknown world, immeasurably far removed, where man was not: and when they perish, something of the gladness goes out of nature, and the sunshine loses something of its brightness.”—W. H. Hudson, inThe Naturalist in La Plata.

Among the extinct animals of prehistoric times the “Great Irish Elk,”[77]as it is generally called, deserves special notice, both from the enormous size of its antlers, and from the fact that its remains are exceedingly plentiful in Ireland.

[77]The term “Elk” is misleading, for it is not an elk (alces) at all, but a trueCervus(stag). It should be called “the Great Irish Deer.”

This magnificent creature, so well depicted by our artist (Plate XXV.), was, however, by no means confined to Ireland; its remains are found in many parts of Great Britain, particularly in cave deposits, and also on the Continent. Some writers think that it was contemporary with men in Ireland; it may have been so, but at present the question cannot be considered as proved. Mr. R. J. Ussher, who found its remains in a cave near Cappagh, Cappoquin, thinks he has obtained evidence to show that it washunted by man at the time when he hunted reindeer in this part of Europe, but the age of the strata containing the remains is doubtful. Again, there is a rib in the Dublin Museum with a perforation which is sometimes taken to be the result of a wound from a dart, arrow, or spear; but the wound may have been inflicted by one of the sharp tynes in a fight between two bucks.

Dr. Hart mentions the discovery of a human body in gravel, under eleven feet of peat, soaked in bog-water, in good preservation, and completely clothed in antique garments of hair, which it has been conjectured might be that of the Great Deer. But if some individual animal had perished and left its body under the like circumstances, its hide and hair ought equally to have been preserved. Dr. Molyneux, to whom we owe the first account of its discovery, says that its extinction in Ireland has occurred “so many ages past, as there remains among us not the least record in writing, or any manner of tradition, that makes so much as mention of its name; as that most laborious inquirer into the pretended ancient but certainly fabulous history of this country, Mr. Roger O’Flaherty, the author ofOgygia, has lately informed me.”[78]

In the romance of the “Niebelungen,” now immortalised by Wagner, which was written in the thirteenth century, the wordshelchoccurs, and is applied to one of the beasts slain in a great hunt a few hundred years before that time in Germany. This word has been cited by some naturalists as probably signifying the Great Irish Deer. But this is mere conjecture, and the word might apply to some big Red Deer. The total silence of Cæsar and Tacitus respecting such remarkable animals renders it highly improbable that they were known to the ancient Britons.

Fig. 57.—Skeleton of Great Irish Deer,Cervus giganteus, from shell-marl beneath the peat, Ireland. Antlers over 9 feet across.

Two entire skeletons of the male, with antlers measuring a little over nine feet from tip to tip, and one skeleton of the hornless doe, are to be seen set up in the middle of the long gallery No. 1 at the Natural History Museum. The drawing inFig. 57is from a specimen in the Museum of the Royal College of Surgeons (Lincoln’s Inn Fields). The height of this specimen to the summit of the antlers is 10 ft. 4 in. The span of the antlers, from tip to tip, is 8 ft. (in the living Moose it is only 4 ft). The weight of the skull and antlers together is 76 lbs., but those of another specimen belonging to the Royal Dublin Society weigh 87 lbs. This great extinct deer surpassed the largest Wapite (Cervus Canadensis) in size, and its antlers were very much larger, wider, and heavier. In some cases the antlers have measured more than 11 ft. from tip to tip. The body of the animal, as well as its antlers, were larger and stronger than in any existing deer. The limbs are stouter, as might be expected from the great weight of the head and neck. Another and more striking feature is the great size of the vertebræ of the neck; this was necessary in order to form a column capable of supporting the head and its massive antlers. (SeePlate XXV.)

PlateXXV.

THE GREAT IRISH DEER, CERVUS MEGACEROS.Height to the summit of the antlers 10 feet; spread of antlers 11 feet.

The first tolerably perfect skeleton was found in the Isle of Man, and presented by the Duke of Athol to the Edinburgh Museum. It was figured in Cuvier’sOssemens Fossiles. Besides those already mentioned at South Kensington and Dublin, there is one in the Woodwardian Museum at Cambridge.

It cannot be doubted that, like all existing deer, the animal shed its antlers periodically, and such shed antlers have been found. When it is recollected that all the osseous matter of which they are composed must have been drawn from the blood carried along certain arteries to the head, in the course of a few months, our wonder may well be excited at the vigorous circulation that took place in these parts.

In the Red Deer the antlers, weighing about 24 lbs., are developed in the course of about ten weeks; but what is that compared to the growth of over 80 lbs. weight in some three or four months?

It is a mistake to suppose that the remains discovered in Ireland were found in peat; they occur not in the peat, but in shell-marls and in claysunder the peat. This is an important point For if the remainswerefound in the peat, they would prove that the Great Deer survived into a later period; instead of being (as is believed from geological evidence) contemporary with the Mammoth and Woolly Rhinoceros in this country, and then disappearing from view. As already stated, it existed on the Continent, and may there have been exterminated by man.

Mr. W. Williams, who has explored several peat-bogs in Ireland, marking the site of ancient lakes, and found many specimens in beds underlying the peat, has given much interesting information bearing upon the question of the period when the Great Deer inhabited Ireland, and the manner in which it was preserved in the lake-beds.[79]He spent ten weeks in 1876-77, excavating deer remains in the bog of Ballybetagh, and subsequently made similar excavations in the counties of Mayo, Limerick, and Meath. These peat-bogs occupy the basins of lakes, the deeper hollows of which have long since been silted up with marls, clays, and sands, and in this silt, or mud, the plants which produced the peat grew. In all the bogs examined he found a general resemblance in the order of succession of the beds, with only slight variations in the nature of the materials such as might be easily accounted for by differences in the surrounding rocks. In these deposits the geologist may read, as in a book, the successive changes in climate that have taken place since the time when the country was deeply covered with snow and ice during the Glacial period.

[79]Geological Magazine, new series, vol. viii. (1881), p. 354.

He found at the bottom of the old Ballybetagh Lake, and resting on the true Boulder Clay (a product of the ice-sheet), a fine stiff clay which seems to have been brought in by the action of rain washing fine clay out of the Boulder Clay, that nearly covered the land, and depositing it in the lake. This action probably took place during a period of thaw, when the climate was damp, from the melting of so much ice, and the rainfall considerable. Then the climate improved, the cold of the Glacial period passed away, and the climate became warm. During this phase the next stratum was formed, consisting chiefly of vegetable remains. The summers must have been unusually warm, dry, and favourable to the growth of vegetation on the bed of the lake. About this time the Great Irish Deer appeared on the scene, for its remains were found resting on this layer, or stratum,in a brownish clay. This deposit also was the product of a time when the climate was mild. It is a true lake-sediment, with seams of clay and fine sand, the latter having been brought down by heavy rainfall from the hills, just as at the present day.

Now, we have to consider how these Great Deer got buried in this deposit. How did they get drowned? They may have gone into the lakes to escape from wolves, or possibly to escape from ancient Britons (but that is still doubtful). Perhaps they went into the water to wallow, as is usual with deer, or they may have ventured to swim the lakes (seep. 19). To enter the lake from a sandy shore would be easy enough, but, on reaching the other side, they might find a soft mud instead, into which their small feet would sink; and the more they plunged and struggled, the worse became their plight, until at last, weary and exhausted, the heavy antlers pressed their heads down under the water, and they were drowned.

It does not follow, according to this theory, that either the entire animal ought to be found, or even its legs, sticking in the clay. For a few days it might remain so, but the motion of the waters of the lake would sway the body to and fro, while the gases due to decomposition would render it buoyant, and perhaps raise it bodily off the bottom. Then it might float before the wind, its head hanging down, till it reached the lee-side of the lake. Then the antlers would get fastened in mud near the shore, thus mooring the body until at last so much of the flesh of the neck had decayed that the body got separated from it, leaving the head and antlers near the shore.

Nearly a hundred heads had been found in this lake previous to Mr. Williams’s explorations, and yet scarcely six skeletons. At first it is somewhat puzzling to account for this scarcity of skeletons compared with heads; but very likely the bodies, minus their heads, were carried right out of the lake, down a river, and perhaps reached the sea or got stranded somewhere down the river in such a way that the bones were never covered up. Butin the Limerick bogs heads and skeletons were often found together. In that district the lakes were probably shallow and with but a feeble current, and so the body never floated away. This explanation by Mr. Williams seems satisfactory.

He reports that the female skulls were rarely met with. Either they were more timid in swimming lakes, or, having no antlers, they may have succeeded in getting out, or the care of their young ones may have kept them out of the lakes during the summer months. The clay in which the remains occur is succeeded by another bed of pure clay, whichneveryields any skulls or bones. This, Mr. Williams thinks, was deposited at a time when the climate was more or less severe, and the musk-ox, reindeer, and other arctic animals came down from more northern regions, even down to the south of France. He concludes that this period marks the extinction of the Great Deer in Ireland, whether rightly or wrongly it is hard to say. Many observers are inclined to think that it lived on to a later period. An interesting fact, having some bearing on the question, is this: that the bones in some cases even yet retain their marrow in the state of a fatty substance, which will burn with a clear lambent flame. Evidence such as this seems to point to a more recent date for its extinction.

Steller’s Sea-Cow.[80]

[80]For fuller information, see theGeological Magazine, decade iii. vol. ii. p. 412. Paper by Dr. Henry Woodward, F.R.S.

The Sirenia of the present day form a remarkable group of aquatic herbivorous animals, really quite distinct from the Cetacea (whales and dolphins), although sometimes erroneously classed with them. In the former group are the Dugong and the Manatee. These creatures pass their whole life in the water, inhabiting the shallow bogs, estuaries, and lagoons, and large rivers, but never venturing far away from the shore. They browsebeneath the surface on aquatic plants, as the terrestrial herbivorous mammals feed upon the green pastures on land.

Not a few of the tales of mermen and mermaids owe their origin to these creatures, as well as to seals, and even walruses. The Portuguese and Spaniards give the Manatee a name signifying “Woman-fish,” and the Dutch call the Dugong the “Little Bearded Man.” A very little imagination, and a memory only for the marvellous, doubtless sufficed to complete the metamorphosis of the half-woman, or man, half-fish, into a siren, a mermaid, or a merman. Hence the general name Sirenia.

The Manatee (Manatus) inhabits the west coast and rivers of tropical Africa, and the east coast and rivers of tropical America, the West Indies, and Florida.

The Dugong (Halicore) extends along the Red Sea coasts, the shores of India, and the adjacent islands, and goes as far as the northern and eastern coasts of Australia.

Fig. 58.—Skeleton ofRhytina gigas(Steller’s “Sea-Cow”), from a peat deposit, Behring’s Island.

The most remarkable Sirenian is the Rhytina gigas, or “Steller’s Sea-Cow.” Early in 1885 the trustees of the British Museum acquired a nearly complete skeleton of this animal, now extinct, from peat deposits in Behring’s Island, of Pleistocene age. Formerly it was abundant along the shores of Kamtchatka, the Kurile Islands, and Alaska. It was first discovered by the German naturalist, Steller, who, in company with Vitus Behring, a captain in the Russian Navy and a celebrated navigator of the northern seas, was with his vessel and crew cast away upon Behring’s Island (where Behring died) in 1741. Steller’s originaldescription is preserved in theMemoirs of the Academy of Sciences St. Petersburg. He saw it alive during his long enforced residence on the island. In the course of forty years, 1742-1782, it appears to have been exterminated, probably for the sake of its flesh and hide, around both Behring’s Island and Copper Island, to the shores of which it was, in Steller’s time, limited.

Fig. 58shows its skeleton, 19 ft. 6 in. long, now preserved in the Geological Collection at South Kensington (Glass-case N). The skeletons are found, in the islands, at a distance from the shore in old raised beaches and peat-mosses, deeply buried and thickly overgrown with grass. They are discovered by boring into the peat with an iron rod, just as timber is found in Irish peat-bogs. (See restoration,Plate XXVI.)

Steller records that when he came to Behring’s Island, the Sea-cows fed in the shallows along the shore, and collected in herds like cattle. Every few minutes they raised their heads in order to get more air before descending again to browse on the thick sea-weed (probably Laminaria) surrounding the coast. With regard to their habits, they were very slow in their movements: mild and inoffensive in disposition. Their colour was dark brown, sometimes varied with spots. The skin was naked; but thick, hard, and rugged. They are said to have sometimes reached a length of thirty-five feet, when full grown. Most of their time was spent in browsing, and whilst so occupied, were not easily disturbed. Their attachment to each other was great, so that when one was harpooned, the others made great attempts to rescue it. According to Steller, they were so heavy that it required forty men with ropes to drag the body of one to land.

PlateXXVI.

STELLER’S SEA-COW, RHYTINA GIGAS.Found alive by Steller at Behring’s Island. Length 19 feet 6 inches.

When, in 1743, the news of the discovery of Behring Island reached Kamtchatka, several expeditions were fitted out for the purpose of hunting the sea-cow and the various fur-bearing animals, such as the sea-otter, fur seal, and blue fox, which are found there; and very soon many whaling vessels began to stop there to lay in a supply of sea-cow meat for food. So great was the destruction wrought by these whalers and fur-hunters that in 1754, only thirteen years after its discovery, the sea-cow had become practically exterminated. In 1768, according to the investigations of Dr. L. Stejneger of the U. S. National Museum, Washington, who has made a most careful study of the question, this large and important marine mammal became wholly extinct, the last individual ever seen alive having been killed in that year; and the fate which overtook Rhytina so speedily has almost become that of the buffalo, and will as certainly become that of the fur seal unless it be protected.

It may interest the reader, especially if he be a traveller, to know that, besides the fine specimen of Rhytina in the Natural History Museum, already alluded to, good skeletons are possessed by the Museums of St. Petersburg, Helsingsfors (Finland), Stockholm, U. S. National Museum, Washington, as well as portions of skeletons by other museums.

The Sirenians are an ancient race, for their remains have been found in Tertiary strata, of various ages, from Eocene to Pleistocene, over the greater part of Europe—in England, Holland, Belgium, France, Germany, Austria, and Italy; also near Cairo. In the New World, fossil Sirenians have been found in South Carolina, New Jersey, and Jamaica.

Another European species is the Halitherium, from the Miocene rocks of Hesse-Darmstadt, of which a cast may be seen in the Natural History Museum, South Kensington. Its length is 7 ft. 8 in. The teeth in this form resembled those of the Dugong.

The Rhytina was probably intermediate between the Dugong and the Manatee, judging from the casts of its brain-cavity. Its brain was very small considering the size of the animals. Altogether, as many as fourteen fossil genera and thirty species are known. Evidently, then, the old Sirenia were once a much more flourishing race. At present, they are confined exclusively to the tropical regions of the earth, and their past distribution, as revealed to the geologists, adds one more proof to the nowwell-established fact, that throughout most of the Tertiary era the climate of northern latitudes was very much warmer than now—in fact, sub-tropical. What cause, or causes, brought about so great a change, we cannot stay to consider here.

In conclusion, it only remains to express a hope that the reader may have been interested in our humble endeavours to describe some of the largest, most strange, and wonderful forms of life that in remote ages have found a home on this planet. And perhaps a few of our readers may be induced to add a new and never-failing interest to their lives by searching in the stony record for traces of the world’s “lost creations.” If so, our labour will not have been in vain.

THE GREAT SEA-SERPENT.

Mr. Henry Lee, formerly naturalist to the Brighton Aquarium, discusses the question of “The Great Sea-Serpent” in an interesting little book, entitledSea Monsters Unmasked, illustrated (1883), published as one of the Handbooks issued in connection with the International Fisheries Exhibition. He goes fully into the history of the subject, and shows how some of the appearances described may be accounted for; but yet is inclined to think that there may exist in the sea animals of great size unknown to science, and concludes as follows:—

“This brings us face to face with the question, ‘Is it, then, so impossible that there may exist some great sea creature, or creatures, with which zoologists are hitherto unacquainted, that it is necessary in every case to regard the authors of such narratives as wilfully untruthful or mistaken in their observations, if their descriptions are irreconcilable with something already known?’ I, for one, am of the opinion that there is no such impossibility. Calamaries or squids of the ordinary size have, from time immemorial, been amongst the commonest and best known of marine animals in many seas; but only a few years ago any one who expressed his belief in one formidable enough to capsize a boat or pull a man out of one was derided for his credulity, although voyagers had constantly reported that in the Indian seas they were so dreaded that the natives always carried hatchets with them in their canoes, with which to cut off the arms or tentacles of these creatures, if attacked by them. We now know that their existence is no fiction; for individuals have been captured measuring more than fifty feet, and some are reported to have measured eighty feet in total length. As marine snakes some feet in length, and having fin-like tails adapted for swimming, abound over an extensive range, and are frequently met with far at sea, I cannot regard it as impossible that some of these also may attain to an abnormal and colossal development. Dr. Andrew Wilson, whohas given much attention to this subject, is of the opinion that ‘in this huge development of ordinary forms we discover the true and natural law of the production of the giant serpent of the sea.’ It goes far at any rate towards accounting for its supposed appearance. I am convinced that whilst naturalists have been searching amongst the vertebrata for a solution of the problem, the great unknown, and therefore unrecognised, Calamaries, by their elongated cylindrical bodies and peculiar mode of swimming, have played the part of the sea-serpent in many a well-authenticated incident. In other cases, such as those mentioned by ‘Pontoppidan’ (History of Norway), the supposed vertical undulations of the snake seen out of water have been the burly bodies of so many porpoises swimming in line—the connecting undulations beneath the surface have been supplied by the imagination. The dorsal fins of basking sharks, as figured by Dr. Andrew Wilson, may have furnished the ‘ridge of fins;’ an enormous conger is not an impossibility; a giant turtle may have done duty, with its propelling flippers and broad back; or a marine snake of enormous size may really have been seen. But if we accept as accurate the observations recorded (which I certainly do not in all cases, for they are full of errors and mistakes), the difficulty is not entirely met, even by this last admission, for the instances are very few in which an Ophidian proper—a true serpent—is indicated. There has seemed to be wanting an animal having a long snake-like neck, a small head, and a slender body, and propelling itself by paddles.

“The similarity of such an animal to the Plesiosaurus of old was remarkable. That curious compound reptile, which has been compared with ‘a snake threaded through the body of a turtle,’ is described by Dean Buckland as having ‘the head of a lizard, the teeth of a crocodile, a neck of enormous length resembling the body of a serpent, the ribs of a chameleon, and the paddles of a whale.’ In the number of its cervical vertebræ (about thirty-three) it surpasses that of the longest-necked bird, the swan.

“The form and probable movements of this ancient Saurian agree so markedly with some of the accounts given of ‘the great sea-serpent,’ that Mr. Edward Newman advanced the opinion that the closest affinities of the latter would be found to be with the Enaliosaurians, or Marine Lizards, whose fossil remains are so abundant in the Oolite and the Lias. This view has been taken by other writers, and emphatically by Mr. Gosse. Neither he nor Mr. Newman insist that ‘the great unknown’ must be the Plesiosaurus itself. Mr. Gossesays, ‘I should not look for any species, scarcely for any genus, to be perpetuated from the Oolitic period to the present. Admitting the actual continuation of the order Enaliosauria, it would be, I think, quite in conformity with general analogy to find some salient features of several extinct forms.’

“The form and habits of the recently recognised gigantic cuttles account for so many appearances which, without knowledge of them, were inexplicable when Mr. Gosse and Mr. Newman wrote, that I think this theory is not forced upon us. Mr. Gosse well and clearly sums up the evidence as follows: ‘Carefully comparing the independent narratives of English witnesses of known character and position, most of them being officers under the Crown, we have a creature possessing the following characteristics: (1) The general form of a serpent; (2) great length, say above sixty feet; (3) head considered to resemble that of a serpent; (4) neck from twelve to sixteen inches in diameter; (5) appendages on the head, neck, or back, resembling a crest or mane (considerable discrepancy in details); (6) colour, dark brown or green, streaked or spotted with white; (7) swims at surface of the water with a rapid or slow movement, the head and neck projected and elevated above the surface; (8) progression steady and uniform, the body straight, but capable of being thrown into convolutions; (9) spouts in the manner of a whale; (10) like a long “nun-buoy.”’ He concludes with the question, ‘To which of the recognised classes of created beings can this huge rover of the ocean be referred?’

“I reply, ‘to the Cephalopoda.’ There is not one of the above judiciously summarised characteristics that is not supplied by the great Calamary, and its ascertained habits and peculiar mode of locomotion.

“Only a geologist can fully appreciate how enormously the balance of probability is contrary to the supposition that any of the gigantic marine Saurians of the secondary deposits should have continued to live up to the present time. And yet I am bound to say that this does not amount to an impossibility, for the evidence against it is entirely negative. Nor is the conjecture that there may be in existence some congeners of these great reptiles inconsistent with zoological science. Dr. J. E. Gray, late of the British Museum, a strict zoologist, is cited by Mr. Gosse as having long ago expressed his opinion that some undescribed form exists which is intermediate between the tortoises and the serpents.” (This is quoted by Mr. Lee in a footnote.)

“Professor Agassiz, too, is adduced by a correspondent of theZoologist(p. 2395), as having said concerning the present existence of the Enaliosaurian type, that ‘it would be in precise conformity with analogy that such an animal should exist in the American seas, as he had found numerous instances in which the fossil forms of the old world were represented by living types in the new.’

“On this point, Mr. Newman records in theZoologist(p 2356), an actual testimony which he considers ‘in all respects the most interesting natural history fact of the present century.’ He writes—

“‘Captain the Hon. George Hope states that when in H.M.S.Fly, in the Gulf of California, the sea being perfectly calm, he saw at the bottom a large marine animal with the head and general figure of the alligator, except that the neck was much longer, and that instead of legs the creature had four large flappers, somewhat like those of turtles, the anterior pair being larger than the posterior, the creature was distinctly visible, and all its movements could be observed with ease; it appeared to be pursuing its prey at the bottom of the sea; its movements were somewhat serpentine, and an appearance of annulations, or ring-like divisions of the body, was distinctly perceptible. Captain Hope made this relation in company, and as a matter of conversation. When I heard it from the gentleman to whom it was narrated, I inquired whether Captain Hope was acquainted with those remarkable fossil animals, Ichthyosauri and Plesiosauri, the supposed forms of which so nearly corresponded with what he describes as having seen alive, and I cannot find that he had heard of them; the alligator being the only animal he mentioned as bearing a partial similarity to the creature in question.’

“Unfortunately, the estimated dimensions of this creature are not given.

“That negative evidence alone is an unsafe basis for argument against the existence of unknown animals, the following illustrations will show:—

“During the deep-sea dredgings of H.M.S.Lightning,Porcupine, andChallenger, many new species of mollusca and others, which had been supposed to have been extinct ever since the Chalk, were brought to light; and by the deep-sea trawlings of the last-mentioned ship there have been brought up from great depths fishes of unknown species, and which could not exist near the surface, owing to the distention and rupture of their air-bladder when removed from the pressure of deep water.

“Mr. Gosse mentions that the ship in which he made the voyageto Jamaica was surrounded in the North Atlantic, for seventeen continuous hours, by a troop of whales of large size, of an undescribed species, which on no other occasion has fallen under scientific observation. Unique specimens of other Cetaceans are also recorded.

“We have evidence, to which attention has been directed by Mr. A. D. Bartlett, that ‘even on land there exists at least one of the largest mammals, probably in thousands, of which only one individual has been brought to notice, namely, the hairy-eared, two-horned rhinoceros (R. Lasiotis), now in the Zoological Gardens, London. It was captured in 1868, at Chittagong, in India, where for years collectors and naturalists have worked and published lists of the animals met with, and yet no knowledge of this great beast was ever before obtained, nor is there any portion of one in any museum. It remains unique.

“I have arrived at the following conclusions: 1. That without straining resemblances, or casting a doubt upon narratives not proved to be erroneous, the various appearances of the supposed ‘great sea-serpent’ may now be nearly all accounted for by the forms and habits of known animals; especially if we admit, as proposed by Dr. Andrew Wilson, that some of them, including the marine snakes, may, like the cuttles, attain to extraordinary size. 2. That to assume that naturalists have perfect cognisance of every existing marine animal of large size, would be quite unwarrantable. It appears to me more than probable that many marine animals, unknown to science, and some of them of gigantic size, may have their ordinary habitat in the sea, and only occasionally come to the surface; and I think it not impossible that amongst them may be marine snakes of greater dimensions than we are aware of, and even a creature having close affinities with the old sea-reptiles whose fossil skeletons tell of their magnitude and abundance in past ages.

“It is most desirable that every supposed appearance of ‘the Great Sea-Serpent’ shall be faithfully noted and described; and I hope that no truthful observer will be deterred from reporting such an occurrence by fear of the disbelief of naturalists or the ridicule of witlings.”
