Chapter 7

1: See DARWIN'SNaturalist's Voyage, ch. iii. for an account of those vitrified siliceous tubes which are formed by lightning entering loose sand. During a thunderstorm which passed over Galle, on the 16th May, 1854, the fortifications were shaken by lightning, and an extraordinary cavity was opened behind the retaining wall of the rampart, where a hole, a yard in diameter, was carried into the ground to the depth of twenty feet, and two chambers, each six feet in length, branched out on either side at its extremity.2: One morning on awaking at Pusilawa, in the hills between Kandy and Neuera-ellia, I was taken to see the effect of a few hours' rain, during the night, on a macadamised road which I had passed the evening before. There was no symptom of a storm at sunset, and the morning was bright and cloudless; but between midnight and dawn such an inundation had swept the highway that in many places the metal had been washed over the face of the acclivity; and in one spot where a sudden bend forced the torrent to impinge against the bank, it had scooped out an excavation extending to the centre of the high road, thirteen feet in diameter, and deep enough to hold a carriage and horses.

This violence, however, seldom lasts more than an hour or two, and gradually abates after intermittent paroxysms, and a serenely clear sky supervenes. For some days, heavy showers continue to fall at intervalsin the forenoon; and the evenings which follow are embellished by sunsets of the most gorgeous splendour, lighting the fragments of clouds that survive the recent storm.

June.—The extreme heat of the previous month becomes modified in June: the winds continue steadily to blow from the south-west, and frequent showers, accompanied by lightning and thunder, serve still further to diffuse coolness throughout the atmosphere and verdure over the earth.

So instantaneous is the response of Nature to the influence of returning moisture, that, in a single day, and almost between sunset and dawn, the green hue of reviving vegetation begins to tint the saturated ground. In ponds, from which but a week before the wind blew clouds of sandy dust, the peasantry are now to be seen catching the re-animated fish; and tank-shells and water-beetles revive and wander over the submerged sedges. The electricity of the air stimulates the vegetation of the trees; and scarce a week will elapse till the plants are covered with the larvæ of butterflies, the forest murmuring with the hum of insects, and the air harmonious with the voice of birds.

The extent to which the temperature is reduced, after the first burst of the monsoon, is not to be appreciated by the indications of the thermometer alone, but is rendered still more sensible by the altered density of the air, the drier state of which is favourable to evaporation, whilst the increase of its movement bringing it more rapidly in contact with the human body, heat is more readily carried off, and the coolness of the surface proportionally increased. It occasionally happens during the month of June that the westerly wind acquires considerable strength, sometimes amounting to a moderate gale. The fishermen, at this period, seldom put to sea: their canoes are drawn far up in lines upon the shore, and vessels riding in the roads ofColombo are often driven from their anchorage and stranded on the beach.

August.—In August the weather is charming, notwithstanding withstanding a slight increase of heat, owing to diminished evaporation; and the sun being now on its return to the equator, its power is felt in greater force on full exposure to its influence.

September.—The same atmospheric condition continues throughout September, but towards its close the sea-breeze becomes unsteady and clouds begin to collect, symptomatic of the approaching change to the north-east monsoon. The nights are always clear and delightfully cool. Rain is sometimes abundant.

Novembersees the close of the south-west monsoon and the arrival of the north-eastern. In the early part of the month the wind visits nearly every point of the compass, but shows a marked predilection for the north, generally veering from N.E. at night and early morning, to N.W. at noon; calms are frequent and precede gentle showers, and clouds form round the lower range of hills. By degrees as the sun advances in its southern declination, and warms the lower half of the great African continent, the current of heated air ascending from the equatorial belt leavesa comparative vacuum, towards which the less rarefied atmospheric fluid is drawn down from the regions north, of the tropic, bringing with it the cold and dry winds from the Himalayan Alps, and the lofty ranges of Assam. The great change is heralded as before by oppressive calms, lurid skies, vivid lightning, bursts of thunder, and tumultuous rain. But at this change of the monsoon the atmospheric disturbance is less striking than in May; the previous temperature is lower, the moisture of the air is more reduced, and the change is less agreeably perceptible from the southern breeze to the dry and parching wind from the north.

December.—In December the sun attains to its greatest southern declination, and the wind setting steadily from the northeast brings with it light but frequent rains from Bay Of Bengal. The thermometer shows a maximum temperature of 85° with a minimum of 70°; the morning and the afternoon are again enjoyable in the open air, but at night every lattice that faces the north is cautiously closed against the treacherous "along-shore-wind."

Notwithstanding the violence and volume in which the rains have been here described as descending during the paroxysms of the monsoons, the total rain-fall in Ceylon is considerably less than on the continent of Throughout Hindustan the annual mean is 117.5 and on some parts on the Malabar coast, upwards of 300 inches have fallen in a single year[1]; whereas the in Ceylon rarely exceeds 80, and the highest registered in an exceptional season was 120 inches.

1: At Mahabaleshwar, in the Western Ghauts, the annual mean is 254 inches, and at Uttray Mullay; in Malabar, 263; whilst at Bengal it is 209 inches at Sylhet; and 610.3 at Cherraponga.

The distribution is of course unequal, both as to time and localities, and in those districts where thefall is most considerable, the number of rainless days is the greatest.[1] An idea may be formed of the deluge that descends in Colombo during the change of the monsoon, from the fact that out of 72.4 inches, the annual average there, no less than 20.7 inches fall in April and May, and 21.9 in October and November, a quantity one-third greater than the total rain in England throughout an entire year.

In one important particular the phenomenon, of the Dekkan affords an analogy for that which presents itself in Ceylon. During the south-west monsoon the clouds are driven against the lofty chain of mountains that overhang the western shore of the peninsula, and their condensed vapour descends there in copious showers. The winds, thus early robbed of their moisture, carry but little rain to the plains of the interior, and whilst Malabar is saturated by daily showers, the sky of Coromandel is clear and serene. In the north-east monsoon a condition the very opposite exists; the wind that then prevails is much drier, and the hills which it encounters being of lower altitude, the rains are carried further towards the interior, and whilst the weather is unsettled and stormy on the eastern shore, the western is comparatively exempt, and enjoys a calm and cloudless sky.[1]

1: The mean of rain is, on the western side of the Dekkan, 80 inches, and on the eastern, 52.8.

In like manner the west coast of Ceylon presents a contrast with the east, both in the volume of rain in each of the respective monsoons, and in the influence which the same monsoon exerts simultaneously on the one side of the island and on the other. The greatestquantity of rain falls on the south-western portion, in the month of May, when the wind from the Indian Ocean is intercepted, and its moisture condensed by the lofty mountain ranges, surrounding Adam's Peak. The region principally affected by it stretches from Point-de-Galle, as far north as Putlam, and eastward till it includes the greater portion of the ancient Kandyan kingdom. But the rains do not reach the opposite side of the island; whilst the west coast is deluged, the east is sometimes exhausted with dryness; and it not unfrequently happens that different aspects of the same mountain present atthe same moment the opposite extremes of drought and moisture.[1]

1: ADMIRAL FITZROY has described, in hisNarrative of the Voyages of the Adventure and Beagle, the striking degree in which this simultaneous dissimilarity of climate is exhibited on opposite sides of the Galapagos Islands; one aspect exposed to the south being covered with verdure and freshened with moisture, whilst all others are barren and parched.—Vol. ii. p. 502-3. The same state of things exists in the east and west sides of the Peruvian Andes, and in the mountains of Patagonia. And no more remarkable example of it exists than in the island of Socotra, east of the Straits of Bab el Mandeb, the west coast of which, during the north-east monsoon, is destitute of rain and verdure, whilst the eastern side is enriched by streams and covered by luxuriant pasturage.—Journ. Asiat. Soc. Beng.vol. iv. p. 141.

One maximum at the spring change of the monsoon anticipating a little that on the West coast of India; another at the autumnal change corresponding more exactly with that of the East coast. The entire fall through the year more equably distributed at Columbo.

On the east coast, on the other hand, the fall, during the north-east monsoon, is very similar in degree to that on the coast of Coromandel, as the mountains are lower and more remote from the sea, the clouds are carried farther inland and it rains simultaneously on both sides of the island, though much less on the west than during the other monsoon.

The climate of Galle, as already stated, resembles in its general characteristics that of Colombo, but, being further to the south, and more equally exposed to the influence of both the monsoons, the temperature is not quite so high; and, during the cold season, it falls some degrees lower, especially in the evening and early morning.[1]

Kandy, from its position, shares in the climate of the western coast; but, from the frequency of the mountain showers, and its situation, at an elevation of upwards of sixteen hundred feet above the level of the sea, it enjoys a much cooler temperature. It differs from the low country in one particular, which is very striking—the early period of the day at which the maximum heat is attained. This at Colombo is generally between two and three o'clock in the afternoon, whereas at Kandy the thermometer shows thehighest temperature of the day between ten and eleven o'clock in the morning.

In the low country, ingenuity has devised so many expedients for defence from the excessive heat of the forenoon, that the languor it induces is chiefly experienced after sunset, and the coolness of the night is insufficient to compensate for the exhaustion of the day; but, in Kandy, the nights are so cool that it is seldom that warm covering can be altogether dispensed with. In the colder months, the daily range of the thermometer is considerable—approaching 30°; in the others, it differs little from 15°. The average mean, however, of each month throughout the year is nearly identical, deviating only a degree from 76°, the mean annual temperature.[1]

Analysis of the Climate at Peradenia, from 1851 to 1858 inclusive.

In all the mountain valleys, the soil being warmer than the air, vapour abounds in the early morning for the most part of the year. It greatly adds to the chilliness of travelling before dawn; but, generally speaking, it is not wetting, as it is charged with the same electricity as the surface of the earth and the human body. When seen from the heights, it is a singular object, as it lies compact and white as snow in the hollows beneath, but it is soon put in motion by the morning currents, and wafted in the direction of the coast, where it is dissipated by the sunbeams.

Snowis unknown in Ceylon;Hailoccasionally falls in the Kandyan hills at the change of the monsoon,[1] but more frequently during that from the north-east. As observed at Kornegalle, the clouds, after collecting as usual for a few evenings, and gradually becoming more dense, advanced in a wedge-like form, with a well-defined outline. The first fall of rain was preceded by a downward blast of cold air, accompanied by hailstones which outstripped the rain in their descent. Rain and hail then poured down together, and, eventually, the latter only spread its deluge far and wide, In 1852, the hail which thus fell at Kornegalle was of such a size that half-a-dozen lumps filled a tumbler, In shape, they were oval and compressed, but the mass appeared to have formed an hexagonal pyramid, the base of which was two inches in diameter, and about half-an-inch thick, gradually thinning towards the edge. They were tolerably solid internally, each containing about the size of a pea of clear ice at the centre, but the sides and angles were spongy and flocculent, as if the particles had been driven together by the force ofthe wind, and had coalesced at the instant of contact. A phenomenon so striking as the fall of ice, at the moment of the most intense atmospherical heat, naturally attracts the wonder of the natives, who hasten to collect the pieces, and preserve them, when dissolved, in bottles, from a belief in their medicinal properties. Mr. Morris, who has repeatedly observed hailstones in the Seven Korles, is under the impression that their occurrence always happens at the first outburst of the monsoon, and that they fall at the moment, which is marked by the first flash of lightning.

1: It is stated in thePhysical Atlasof KEITH JOHNSTON, that hail in India has not been noticed south of Madras. But in Ceylon it has fallen very recently at Korngalle, at Badulla, at Kaduganawa; and I have heard of a hail storm at Jaffna. On 1 the 24th of Sept. 1857, during a thunder-storm, hail fell near Matelle in such quantity that in places it formed drifts upwards of a foot in depth.

According to Professor Stevelly, of Belfast, the rationale of their appearance on such occasions seems to be that, on the sudden formation and descent of the first drops, the air expanding and rushing into the void spaces, robs the succeeding drops of their caloric so effectually as to send them to the earth frozen into ice-balls.

These descriptions, it will be observed, apply exclusively to the southern regions on the east and west of Ceylon; and, in many particulars, they are inapplicable to the northern portions of the island. At Trincomalie, the climate bears a general resemblance to that of the Indian peninsula south of Madras: showers are frequent, but light, and the rain throughout the year does not exceed forty inches. With moist winds and plentiful dew, this sustains a vigorous vegetation near the coast; but in the interior it would be insufficient for the culture of grain, were not the water husbanded in tanks; and, for this reason, the bulk of the population are settled along the banks of the great rivers.

The temperature of this part of Ceylon follows the course of the sun, and ranges from a minimum of 70° in December and January, to a maximum of 94° in May and June; but the heat is rendered tolerable at all seasons by the steadiness of the land and sea breezes.[1]

1: The following facts regarding the climate of Trincomalie have been, arranged from elaborate returns furnished by Mr. Higgs, the master-attendant of the port, and published under the authority of the meteorological department of the Board of Trade:—Trincomalie.1854Mean Maximum TemperatureMean Minimum TemperatureExtreme Range for the MonthHighest Temperature NotedDays of RainJan.81.3°74.7°14°8310Feb.83.875.814867Mar.85.976.116883April89.678.916923May89.179.319933June90.079.519943July87.777.716905Aug.87.977.416914Sept.89.377.818932Oct.85.275.8158914Nov.81.074.9118315Dec.80.174.3118215Mean temperature for the year 81.4.

In the extreme north of the island, the peninsula of Jaffna, and the vast plains of Neura-kalawa and the Wanny, form a third climatic division, which, from the geological structure and peculiar configuration of the district, differs essentially from the rest of Ceylon. This region, which is destitute of mountains, is undulating in a very slight degree; the dry and parching north-east wind desiccates the soil in its passage, and the sandy plains are covered with a low and scanty vegetation, chiefly fed by the night dews and whatever moisture is brought by the on-shore wind. The total rain of the year does not exceed thirty inches; and the inhabitants live in frequent apprehension of droughts and famines. These conditions attain their utmost manifestation at the extreme north and in the Jaffna peninsula: there the temperature is the highest[1] in the island, and, owing to the humidity of the situation and the total absence of hills, it is but little affected by the changes of the monsoons; and the thermometer keeps a regulated pace with the progress of the sun to and from the solstices. The soil, except in particular spots, is porous and sandy, formed from the detritus of the coral rocks which it overlays. It is subject to droughts sometimes of a wholeyear's continuance; and rain, when it falls, is so speedily absorbed, that it renders but slight service to cultivation, which is entirely carried on by means of tanks and artificial irrigation, in the practice of which the Tamil population of this district exhibits singular perseverance and ingenuity.[2] In the dry season, when scarcely any verdure is discernible above ground, the sheep and goats feed on their knees—scraping away the sand, in order to reach the wiry and succulent roots of the grasses. From the constancy of this practice horny callosities are produced, by which these hardy creatures may be distinguished.

1: The mean lowest temperature at Jaffna is 70º, the mean highest 90º; but in 1845-6 the thermometer rose to 90º and 100º.2: For an account of the Jaffna wells, and the theory of their supply with fresh water, seech. i. p. 21.

Water-spouts are frequent on the coast of Ceylon, owing to the different temperature of the currents of air passing across the heated earth and the cooler sea, but instances are very rare of their bursting over land, or of accidents in consequence.[1]

1: CAMOENS, who had opportunities of observing the phenomena of these seas during his service on board the fleet of Cabral, off the coast of Malabar and Ceylon, has introduced into theLusiadthe episode of a water-spout in the Indian Ocean; but, under the belief that the water which descends had been previously drawn up by suction from the ocean, he exclaims:—"But say, ye sages, who can weigh the cause,And trace the secret springs of Nature's laws;Say why the wave, of bitter brine erewhile,Should be the bosom of the deep recoil,Robbed of its salt, and from the cloud distil,Sweet as the waters of the limpid rill?"(Book v.)But the truth appears to be that the torrent which descends from a water-spout, is but the condensed accumulation of its own vapour, and, though in the hollow of the lower cone which rests upon the surface of the sea, salt water may possibly ascend in the partial vacuum caused by revolution; or spray may be caught up and collected by the wind, still these cannot be raised by it beyond a very limited height, and what Camoens saw descend was, as he truly says, the sweet water distilled from the cloud.

"But say, ye sages, who can weigh the cause,And trace the secret springs of Nature's laws;Say why the wave, of bitter brine erewhile,Should be the bosom of the deep recoil,Robbed of its salt, and from the cloud distil,Sweet as the waters of the limpid rill?"

"But say, ye sages, who can weigh the cause,

And trace the secret springs of Nature's laws;

Say why the wave, of bitter brine erewhile,

Should be the bosom of the deep recoil,

Robbed of its salt, and from the cloud distil,

Sweet as the waters of the limpid rill?"

(Book v.)

But the truth appears to be that the torrent which descends from a water-spout, is but the condensed accumulation of its own vapour, and, though in the hollow of the lower cone which rests upon the surface of the sea, salt water may possibly ascend in the partial vacuum caused by revolution; or spray may be caught up and collected by the wind, still these cannot be raised by it beyond a very limited height, and what Camoens saw descend was, as he truly says, the sweet water distilled from the cloud.

A curious phenomenon, to which the name of "anthelia" has been given, and which may probably have suggested to the early painters the idea of the glory surrounding the heads of beatified saints, is to be seen in singular beauty, at early morning, in Ceylon. When the light is intense, and the shadows proportionally dark—when the sun is near the horizon, and the shadow of a person walking is thrown on the dewy grass—each particle of dew furnishes a double reflection from its concaveand convex surfaces; and to the spectator his own figure, but more particularly the head, appears surrounded by a halo as vivid as if radiated from diamonds.[1] The Buddhists may possibly have taken from this beautiful object their idea of theagnior emblem of the sun, with which the head of Buddha is surmounted. But unable to express ahaloin sculpture, they concentrated it into aflame.

1: SCORESBY describes the occurrence of a similar phenomenon in the Arctic Seas in July, 1813, the luminous circle being produced on the particles of fog which rested on the calm water. "The lower part of the circle descended beneath my feet to the side of the ship, and although it could not be a hundred feet from the eye, it was perfect, and the colours distinct. The centre of the coloured circle was distinguished by my own shadow, the head of which, enveloped by a halo, was most conspicuously pourtrayed. The halo or glory evidently impressed on the fog, but the figure appeared to be a shadow on the water; the different parts became obscure in proportion to their remoteness from the head, so that the lower extremities were not perceptible."—Account of the Arctic Regions, vol. i. ch. v. sec. vi. p. 394. A similar phenomenon occurs in the Khasia Hills, in the north-east of Bengal.—Asiat. Soc. Journ. Beng.vol. xiii. p. 616.

THE ANTHELIA AS IT APPEARS TO THE PERSON HIMSELF

Another luminous phenomenon which sometimes appears in the hill country, consists of beams of light, which intersect the sky, whilst the sun is yet in the ascendant; sometimes horizontally, accompanied by intermitting movements, and sometimes vertically, a broad belt of the blue sky interposing between them.[1]

1: VIGNE mentions an appearance of this kind in the valley of Kashmir: "Whilst the rest of the horizon was glowing golden over the mountain tops, a broad well-defined ray-shaped streak of indigo was shooting upwards in the zenith: it remained nearly stationary about an hour, and was then blended into the sky around it, and disappeared with the day. It was, no doubt, owing to the presence of some particular mountains which intercepted the red rays, and threw a blue shadow, by causing so much of the sky above Kashmir to remain unaffected by them."—Travels in Kashmir, vol. ii. ch. x. p. 115.

In Ceylon this is doubtless owing to the air holding in suspension a large quantity of vapour, which receives shadows and reflects rays of light. The natives, who designate them "Buddha's rays," attach a superstitious dread to their appearance, and believe them to be portentous of misfortune—in every month, with the exception ofMay, which, for some unexplained reason, is exempted.

HEALTH.—In connection with the subject of "Climate," one of the most important inquiries is the probable effect on the health and constitution of a European produced by a prolonged exposure to an unvarying temperature, upwards of 30 degrees higher than the average of Great Britain. But to this the most tranquillising reply is the assurance thatmere heat, even to a degree beyond that of Ceylon, is not unhealthy in itself. Aden, enclosed in a crater of an extinct volcano, is not considered insalubrious; and the hot season in India, when the thermometer stands at 100° at midnight, is comparatively a healthy period of the year. In fact, in numerous cases heat may be the means of removing the immediate sources of disease. Its first perceptible effect is a slight increase, of the normal bodily temperature beyond 98°, and, simultaneously, an increased activity of all the vital functions. To this everything contributes an exciting sympathy—the glad surprise of the natural scenery, the luxury of verdure, the tempting novelty of fruits and food, and all the unaccustomed attractions of a tropical home. Under these combined influences the nervous sensibility is considerably excited, and the circulation acquires greater velocity, with somewhat diminished force. This is soon followed,however, by the disagreeable evidences of the effort made by the system to accommodate itself to the new atmospheric condition. The skin often becomes fretted by "prickly heat," or tormented by a profusion of boils, but relief being speedily obtained through these resources, the new comer is seldom afterwards annoyed by a recurrence of the process, unless under circumstances of impaired tone, the result of weakened digestion or climatic derangement.

Malaria.—Compared with Bengal and the Dekkan, the climate of Ceylon presents a striking superiority in mildness and exemption from all the extremes of atmospheric disturbance; and, except in particular localities, all of which are well known and avoided[1], from being liable after the rains to malaria, or infested at particular seasons with agues and fever, a lengthened residence in the island may be contemplated, without the slightest apprehension of prejudicial results. These pestilential localities are chiefly at the foot of mountains, and, strange to say, in the vicinity of some active rivers, whilst the vast level plains, whose stagnant waters are made available for the cultivation of rice, are seldom or never productive of disease. It is even believed that the deadly air is deprived of its poison in passing over an expanse of still water; and one of the most remarkable circumstances is, that the points fronting the aerial currents are those exposed to danger, whilst projecting cliffs, belts of forest, and even moderately high walls, serve to protect all behind them from attack.[2] In traversingdistricts suspected of malaria, experience has dictated certain precautions, which, with ordinary prudence and firmness, serve to neutralise the risk—retiring punctually at sunset, generous diet, moderate stimulants, and the daily use of quinine both before and after exposure. These, and the precaution, at whatever sacrifice of comfort, to sleep under mosquito curtains, have been proved in long journeys to be valuable prophylactics against fever and the pestilence of the jungle.

1: Notwithstanding this general condition, fevers of a very serious kind have been occasionally known to attack persons on the coast, who had never exposed themselves to the miasma of the jungle. Such instances have occurred at Galle, and more rarely at Colombo. The characteristics of places in this regard have, in some instances, changed unaccountably; thus at Persadenia, close to Kandy, it was at one time regarded as dangerous to sleep.2: Generally speaking, a flat open country is healthy, either when flooded deeply by rains, or when dried to hardness by the sun; but in the process of dessication, its exhalations are perilous. The wooded slopes at the base of mountains are notorious for fevers; such as theterraiof the Nepal hills, the Wynaad jungle, at the foot of the Ghauts, and the eastern side of the mountains of Ceylon.

Food.—Always bearing in mind that of the quantity of food habitually taken in a temperate climate, a certain proportion is consumed to sustain the animal heat, it is obvious that in the glow of the tropics, where the heat is already in excess, this portion of the ingesta not only becomes superfluous so far as this office is concerned, but occasions disturbance of the other functions both of digestion and elimination. Over-indulgence in food, equally with intemperance in wine, is one fruitful source of disease amongst Europeans in Ceylon; and maladies and mortality are often the result of the former, in patients who would repel as an insult the imputation of the latter.

So well have national habits conformed to instinctive promptings in this regard, that the natives of hot countries have unconsciously sought to heighten the enjoyment of food by taking their principal repastafter sunset[1]; and the European in the East will speedily discover for himself the prudence, not only of reducing the quantity, but in regard to the quality of his meals, of adopting those articles which nature has bountifullysupplied as best suited to the climate. With a moderate use of flesh meat, vegetables, and especially farinaceous food, are chiefly to be commended.

1: The prohibition of swine, which has formed an item in the dietetic ritual of the Egyptians, the Hebrews, and Mahometans, has been defended in all ages, from Manetho and Herodotus downwards, on the ground that the flesh of an animal so foully fed has a tendency to promote cutaneous disorders, a belief which, though held as a fallacy in northern climates, may have a truthful basis in the East.—ÆLIAN,Hist. Anim.1. X. 16. In a recent general order Lord Clyde has prohibited its use in the Indian army. Camel's flesh, which is also declared unclean in Leviticus, is said to produce in the Arabs serious derangement of the stomach.

The latter is rendered attractive by the unrivalled excellence of the Singhalese in the preparation of innumerable curries[1], each tempered by the delicate creamy juice expressed from the flesh of the coco-nut after it has been reduced to a pulp. Nothing of the same class in India can bear a comparison with the piquant delicacy of a curry in Ceylon, composed of fresh condiments and compounded by the skilful hand of a native.

1: The popular error of thinking curry to be an invention of the Portuguese in India is disproved by the mention in theRajavaliof its use in Ceylon in the second century before the Christian era, and in theMahawansoin the fifth century of it. This subject is mentioned elsewhere: see chapter on the Arts and Sciences of the Singhalese.

The use of fruit—Fruits are abundant and wholesome; but with the exception of oranges, pineapples, the luscious mango and the indescribable "rambutan," for want of horticultural attention they are inferior in flavour, and soon cease to be alluring.

Wine.—Wine has of late years become accessible to all, and has thus, in some degree, been substituted for brandy; the abuse of which at former periods is commemorated in the records of those fearful disorders of the liver, derangements of the brain, exhausting fevers, and visceral diseases, which characterise the medical annals of earlier times. With a firm adherence to temperance in the enjoyment of stimulants, and moderation in the pleasures of the table, with attention to exercise and frequent resort to the bath, it may be confidently asserted that health in Ceylon is as capable of preservation and life as susceptible of enjoyment, as in any country within the tropics.

Exposure.—Prudence and foresight are, however, as indispensable there as in any other climate to escape well-understood risks. Catarrhs and rheumatism areas likely to follow needless exposure to the withering "along-shore wind" of the winter months in Ceylon[1], as they are traceable to unwisely confronting the east winds of March in Great Britain; and during the alternation, from the sluggish heat which precedes the monsoon, to the moist and chill vapours that follow the descent of the rains, intestinal disorders, fevers, and liver complaints are not more characteristic of an Indian monsoon than an English autumn, and are equally amenable to those precautions by which liability may be diminished in either place.

1: Seeante,p. 57. It is an agreeable characteristic of the climate of Ceylon, that sun-stroke, which is so common even in the northern portions of India, is almost unknown in the island. Sportsmen are out all day long in the hottest weather, a practice which would be thought more than hazardous in Oude or the north-west provinces. Perhaps an explanation of this may be found in the difference in moisture in the two atmospheres, which may modify the degrees of evaporation; but the inquiry is a curious one. It is becoming better understood in the army that active service, and even a moderate exposure to the solar rays (always guarding them from the head,) are conducive rather than injurious to health in the tropics. The pale and sallow complexion of ladies and children born in India, is ascribable in a certain degree to the same process by which vegetables are blanched under shades which exclude the light:—they are reared in apartments too carefully kept dark.

Paleness.—At the same time it must be observed, that the pallid complexion peculiar to old residents, is not alone ascribable to an organic change in the skin from its being the medium of perpetual exudation, but in part to a deficiency of red globules in the blood, and mainly to a reduced vigour in the whole muscular apparatus, including the action of the heart, which imperfectly compensates by increased rapidity for diminution of power. It is remarkable how suddenly this sallowness disappears, and is succeeded by the warm tints of health, after a visit of a very few days to the plains of Neuera-ellia, or the picturesque coffee plantations in the hills that surround it.

Ladies.—Ladies, from their more regular and moderate habits, and their avoidance of exposure, might be expected to withstand the climate better than men;and to a certain extent the anticipation appears to be correct, but it by no means justifies the assumption of general immunity. Though less obnoxious to specific disease, debility and delicacy are the frequent results of habitual seclusion and avoidance of the solar light. These, added to more obvious causes of occasional illness, suggest the necessity of vigorous exertion and regular exercise as indispensable protectives.

If suitably clothed, and not injudiciously fed, children may remain in the island till eight or ten years of age, when anxiety is excited by the attenuation of the frame and the apparent absence of strength in proportion to development. These symptoms, the result of relaxed tone and defective nutrition, are to be remedied by change of climate either to the more lofty ranges of the mountains, or, more providently, to Europe.

Effects on Europeans already Diseased.—To persons already suffering from disease, the experiment of a residence in Ceylon is one of questionable propriety. Those of a scrofulous diathesis need not consider it hazardous, as experience does not show that in such there is any greater susceptibility to local or constitutional disorders, or that when these are present, there is greater difficulty in their removal.

To those threatened with consumption, the island may be supposed to offer some advantages in the equability of the temperature, and the comparative quiescence of the lungs from reduced necessity for respiratory effort. Besides, the choice of climates presented by Ceylon enables a patient, by the easy change of residence to a different altitude and temperature, avoiding the heats of one period and the dry winds of another, to check to a great extent the predisposing causes likely to lead to the development of tubercle. This, with attention to clothing and systematic exercise as preventives of active disease, may serve to restrain the further progress though it fail to eradicate the tendency to phthibis. But when already the formation of tuberclehas taken place to any considerable extent, and is accompanied by softening, the morbid condition is not unlikely to advance with alarming celerity; and the only compensating circumstance is the diminution of apparent suffering, ascribable to general languor, and the absence of the bronchial irritation occasioned by cold humid air.

Dyspepsia.—Habitual dyspeptics, and those affected by hepatic obstructions, had better avoid a lengthened sojourn in Ceylon; but the tortures of rheumatism and gout, if they be not reduced, are certainly postponed for longer intervals than those conceded to the same sufferers in England. Gout, owing to the great cutaneous excretion, in most instances totally disappears.

Precautions for Health.—Next to attention to diet, health in Ceylon is mainly to be preserved by systematic exercise, and a costume adapted to the climate and its requirements. Paradoxical as it may sound, the great cause of disease in hot climates iscold. Nothing ought more cautiously to be watched and avoided than the chills produced by draughts and dry winds; and a change of dress or position should be instantly resorted to when the warning sensation of chilliness is perceived.

Exercise.—The early morning ride, after a single cup of coffee and a biscuit on rising, and the luxury of the bath before dressing for breakfast, constitute the enjoyments of the forenoon; and a similar stroll on horseback, returning at sunset to repeat the bath[1] preparatory to the evening toilette, completes the hygienic discipline of the day. At night the introduction of the Indian punka into bed-rooms would be valuable, a thin flannel coverlet being spread over the bed. Nothingserves more effectually to break down an impaired constitution in the tropics than the want of timely and refreshing sleep.
