On these climates in general Dr. Lind observes, that in well cultivated countries, such as China, the air is temperate and wholesome; while the woody and uncultivated parts prove fatal to multitudes accustomed to breathe a purer air. In all places also, near the muddy and impure banks of rivers, or the foul shores of the sea, mortal diseases are produced from the exhalations, especially during the rainy season. “There is a place near Indrapour, in Sumatra, where no European can venture to remain, or sleep one night on shore, during the rainy season, without running the hazard of his life, or at least of a dangerous fit of sickness; and at Podang, a Dutch settlement on Sumatra, the air has been found so bad, that it is commonly called the Plague-Coast. Here a thick, pestilential vapour or fog arises, after the rains, from the marshes, which destroys all the white inhabitants.” In treating of the diseases of Africa, the same author takes notice of those of Egypt; which country, he says, is rendered unwholesome by the annual inundation of the Nile, and being surrounded on three sides by large and extensive deserts of sand, by which means it is exposed to the effects of that noisome vapour, which, during the summer months, arises from sultry, hot sand. He doth not, however, say, that the true plague originates in this country, either from the inundation of the Nile or any other cause. On the climate of Egypt I shall once more quote M. Savary, who is a strenuous advocate for its healthiness, and is at pains to confute the opinion of Mr. Pauw, and others, who assert the contrary. “Mr. Pauw (says he) pretends, that at present Egypt is become, by the negligence of the Turks and Arabs, the cradle of the pestilence; that another epidemical disease, equally dreadful, appears here, by the caravans of Nubia; that the culture of rice engenders numerous maladies; that the want of rain and thunder occasions the air of the Thebais to acquire a violence that ferments the humours of the human body, &c.” “These assertions (M. Savary observes) have an air of probability, which might impose on people who have not lived in Egypt; but Mr. Pauw has ventured opinions in his closet, without the guidance of experience. In vallies, indeed, enclosed by high mountains, where the atmosphere is not continually renewed by a current of air, the culture of rice is unwholesome, but not so, near Damietta and Rosetta. The plains are nearly on a level with the sea; neither hill nor height impedes the refreshing breath of the north, which drives the clouds and exhalations off the flooded fields southwards, continually purifies the atmosphere, and preserves the health of the people; so that the husbandmen who cultivate the rice are not more subject to diseases than those who do not. The heats of the Thebais certainly surpass those of many countries under the equator. Reaumer’s thermometer, when the burning breath of the south is felt,
