_Wine_.--Wine has of late years become accessible to all, and has thus, in some degree, been subst.i.tuted 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 a.s.serted 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 are as likely to follow needless exposure to the withering ”along-sh.o.r.e 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.
[Footnote 1: See _ante_, 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 antic.i.p.ation appears to be correct, but it by no means justifies the a.s.sumption 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 const.i.tutional 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 alt.i.tude 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 tubercle has 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 circ.u.mstance 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 is _cold_. 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, const.i.tute 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.
Nothing serves more effectually to break down an impaired const.i.tution in the tropics than the want of timely and refres.h.i.+ng sleep.
[Footnote 1: ”Je me souviens que les deux premieres annees que je fus en ce pais-la, j'eus deux maladies: _alors je pris la coutume de me bien laver soir et matin_, et pendant 16 ans que j'y ay demeure depuis, je n'ay pas senti le moindre mal.”--RIBEYRO, _Hist. de l'Isle de Ceylan_, vol. v. ch. xix. p. 149.]
_Dress_.--In the selection of dress experience has taught the superiority of calico to linen, the latter, when damp from the exhalation of the skin, causing a chill which is injurious, whilst the former, from some peculiarity in its fibre, however moist it may become, never imparts the same sensation of cold. The clothing best adapted to the climate is that whose texture least excites the already profuse perspiration, and whose fas.h.i.+on presents the least impediment to its escape.[1] The discomfort of woollen has led to its avoidance as far as possible; but those who, in England, may have accustomed themselves to flannel, will find the advantage of persevering to wear it, provided it is so light as not to excite perspiration. So equipped for active exercise, exposure to the sun, however hot, may be regarded without apprehension, provided the limbs are in motion and the body in ordinary health; but the instinct of all oriental races has taught the necessity of protecting the head, and European ingenuity has not failed to devise expedients for this all-important object.
[Footnote 1: ”Man not being created an aquatic animal, his skin cannot with impunity be exposed to perpetual moisture, whether directly applied or arising from perspiration retained by dress. The importance to health of keeping the skin _dry_ does not appear to have hitherto received due attention.”--PICKERING, _Races of Man_, &c., ch. xliv.]
From what has been said, it will be apparent that, compared with continental India, the securities for health in Ceylon are greatly in favour of the island. As to the formidable diseases which are common to both, their occurrence in either is characterised by the same appalling manifestations: dysentery fastens, with all its fearful concomitants, on the unwary and incautious; and cholera, with its dark horrors, sweeps mysteriously across neglected districts, exacting its hecatombs. But the visitation and ravages of both are somewhat under control, and the experience bequeathed by each gloomy visitation has added to the facilities for checking its recurrence.[1]
[Footnote 1: ”It is worthy of remark, that although all the troops in Ceylon have occasionally, but at rare intervals; suffered severely from cholera, the disease has in very few instances attacked the officers; or indeed Europeans in the same grade of life. This is one important difference to be borne in mind when estimating the comparative risk of life in India and Ceylon. It must be due to the difference in comforts and quarters, or more particularly to the exemption from night duty, by far the most trying of the soldiers' hards.h.i.+ps. The small mortality amongst the officers of European regiments in Ceylon is very remarkable.”--_Note_ by Dr. CAMERON, Army Med. Staff.]
In some of the disorders incidental to the climate, and the treatment of ulcerations caused by the wounds of the mosquitoes and leeches, the native Singhalese have a deservedly high reputation; but their practice, when it depends on specifics, is too empirical to be safely relied on; and their traditional skill, though boasting a well authenticated antiquity, achieves few triumphs in compet.i.tion with the soberer discipline of European science.
CHAP. III.
VEGETATION.--TREES AND PLANTS.
Although the luxuriant vegetation of Ceylon has at all times been the theme of enthusiastic admiration, its flora does not probably exceed 3000 phaenogamic plants[1]; and notwithstanding that it has a number of endemic species, and a few genera, which are not found on the great Indian peninsula, still its botanical features may be described as those characteristic of the southern regions of Hindustan and the Dekkan. The result of some recent experiments has, however, afforded a curious confirmation of the opinion ventured by Dr. Gardner, that, regarding its botany geographically, Ceylon exhibits more of the Malayan flora and that of the Eastern Archipelago, than of any portion of India to the west of it. Two plants peculiar to Malacca, the nutmeg and the mangustin, have been attempted, but unsuccessfully, to be cultivated in Bengal; but in Ceylon the former has been reared near Colombo with such singular success that its produce now begins to figure in the exports of the island;--and mangustins, which, ten years ago, were exhibited as curiosities from a single tree in the old Botanic Garden at Colombo, are found to thrive readily, and they occasionally appear at table, rivalling in their wonderful delicacy of flavour those which have heretofore been regarded as peculiar to the Straits.
[Footnote 1: The prolific vegetation of the island is likely to cause exaggeration in the estimate of its variety. Dr. Gardner, shortly after his appointment as superintendent of the Botanic Garden at Kandy, in writing to Sir W. Hooker, conjectured that the Ceylon flora might extend to 4000 or 5000 species. But from a recent _Report_ of the present curator, Mr. Thwaites, it appears that the indigenous phaenogamic plants discovered up to August, 1856, was 2670; of which 2025 were dicotyledonous, and 644 monocotyledonous flowering plants, besides 247 ferns and lycopods. When it is considered that this is nearly double the indigenous flora of England, and little under _one thirtieth_ of the entire number of plants. .h.i.therto described over the world, the botanical richness of Ceylon, in proportion to its area, must be regarded as equal to that of any portion of the globe.]
Up to the present time the botany of Ceylon has been imperfectly submitted to scientific scrutiny. Linnaeus, in 1747, prepared his _Flora Zeylanica_, from specimens collected by Hermann, which had previously const.i.tuted the materials of the _Thesaurus Zeylanicus_ of Burman and now form part of the herbarium in the British Museum. A succession of industrious explorers have been since engaged in following up the investigation[1]; but, with the exception of an imperfect and unsatisfactory catalogue by Moon, no enumeration of Ceylon plants has yet been published. Dr. Gardner had made some progress with a Singhalese Flora, when his death took place in 1849, an event which threw the task on other hands, and has postponed its completion for years.[2]
[Footnote 1: Amongst the collections of Ceylon plants deposited in the Hookerian Herbarium, are those made by General and Mrs. Walker, by Major Champion (who left the island in 1848), and by Mr. Thwaites, who succeeded Dr. Gardner in charge of the Royal Botanic Gardens at Kandy.
Moon, who had previously held that appointment, left extensive collections in the herbarium at Peradenia which have been lately increased by his successors; and Macrae, who was employed by the Horticultural Society of London, has enriched their museum with Ceylon plants. Some admirable letters of Mrs. Walker are printed in HOOKER'S _Companion to the Botanical Magazine_. They include an excellent account of the vegetation of Ceylon.]
