The climate of Isle St. Louis is mild, wholesome, and agreeable during eight months of the year. From the beginning of December to the end of July, the temperature may be compared to that of our finest summer days; though cold is often felt there. All the houses have chimnies, which shews, that it is necessary to have fire in them during certain days in the year; but they are kindled only in the morning and evening, as the rays of the sun heat the atmosphere sufficiently. This brilliant orb shines in these countries in all its splendour during the eight months already mentioned. The sky is pure and cloudless; fresh winds purify the atmosphere; and the cold which occurs at intervals is a real benefit bestowed by nature for the health of the inhabitants. Diseases are as rare at this period as they are frequent in the months of August, September, October, and November, which are comprised under the name of the sickly season, and during which time rain falls in abundance. The winds are at this epoch easterly; they cross the burning sands of Africa, and, corrupted by the fetid exhalations from the marshes, carry contagion to the island. Hence dysenteries, with putrid and inflammatory fevers, become frequent, and often make great havoc. To secure oneself against their malign influence, it is necessary to avoid all excesses, and particularly to guard against sleeping in the daytime: it is also of great advantage to drink fasting a little brandy in which bark has been infused; to take wholesome food in small quantities; and to bathe every day. The air is purified by burning gum, which the country furnishes in abundance. I passed two such seasons at Isle St. Louis without experiencing the least inconvenience; and others have lived there twenty, thirty, and forty years, and were equally fortunate as myself. When, however, a person is attacked, he has no occasion to despair of a cure: for the doctors use several good remedies; but the best specific is an emetic, by the taking of which in proper time, I have known several persons completely restored to health. I admit that such attacks are dangerous: but it is an error to suppose them incurable; as it likewise is to believe that the climate is always unhealthy: indeed I do not know a better one during two thirds of the year; and the dangers of the other portion have been exaggerated by travellers and historians. The latter have never been in Africa; and the former have accustomed themselves to assert falsehoods. There have never been any physicians at Isle St. Louis; but surgeons are established there by government, which has not always been fortunate in its choice. To well informed men the country would present remedies in its own productions: for the natives prevent disease, or cure themselves when afflicted, by simples which are unknown to us at present; and here it is probable that by attentive observation very useful discoveries might be made.
