to the glanders, which may possibly be owing to their drinking in a different manner from horses; for instead of dipping in the mouth and nose deeply into the water, they scarcely touch it with their lips. I shall not speak of the other diseases of horses, it would spin out Natural History too much to join to the history of an animal that of its disorders; nevertheless, I cannot leave the history of the horse without regretting that the health of this useful animal should have been hitherto abandoned to the care, and too frequently absurd practice, of ignorant people. The branch of physic, which the ancients called Veterinaria Medicina, is at present scarcely known but by name. I am persuaded, that if some physician would turn his views this way, and make this study his principal object, he would soon find it answer his purpose, both with respect to reputation and profit: instead of degrading himself he would render his name illustrious, and this branch of physic would not be so conjectural and difficult as the other. The diet, manners, and influence of sentiment, and all other causes of disorders, being more simple in animals than in man, the diseases must be less complicated, and consequently more easily investigated, and treated with success, without mentioning the advantages that would be derived from the entire liberty of making experiments, trying new remedies, and to be able to arrive, without fear or reproach, to a great extent of knowledge of this kind, from which, by analogy, inferences might be drawn useful to the art of curing mankind. SUPPLEMENT. Africa, it has already been observed, appears to be the original climate of the horse, and from the country being so dry and warm, admits many customs that cannot be practised in the northern regions, at least with any effect. In different countries they not only receive different food, but are also differently managed. In Arabia and Barbary they scarcely ever are allowed herbage or grain, but are principally kept upon dates and camel's milk, which is given them morning and evening; they are seldom made use of till the seventh year, till when they suck the camels whom they constantly follow.
