THE next (though not a dangerous complaint) has a very terrible appearance. Small tubercules or swellings appear all over the body, but thickest in the thighs, arms, and legs. These swellings go and come for weeks together without pain; though the legs often swell to a monstrous size as in the dropsy. Sometimes the patients have ulcers in their noses and mouths, not unlike those which are one of the malignant consequences of the venereal disease. The small swellings or eruptions, when squeezed, very often yield blood; in other respects the patient is generally in good health, saving the pain the ulcers give him, and the still greater uneasiness of mind which he suffers from the spoiling of the smoothness of his skin; for all the nations in Africa within the tropics are wonderfully affected at the smallest eruption or roughness of the skin. A black of Sennaar will hide himself in the house where dark, and is not to be seen by his friends, if he should have two or three pimples on any part of his body. Nor is there any remedy, however violent, that they will not fly to for immediate relief. Scars and wounds are no blemishes; and I have seen them, for three or four pimples on their bracelet arm, suffer the application of a red-hot iron with great resolution and constancy. These two last diseases yielded, the first slowly, and sometimes imperfectly, to mercurials; and sublimate has by no means in these climates the quick and decisive effects it has in Europe. The second is completely and speedily cured by antimonials. The next complaint I shall mention, as common in these countries, is called Farenteit, a corruption of an Arabic word, which signifies the worm of Pharaoh; all bad things being by the Arabs attributed to these poor kings, who seem to be looked upon by posterity as the evil genii of the country which they once governed. This extraordinary animal only afflicts those who are in constant habit of drinking stagnant water, whether that water is drawn out from wells, as in the kingdom of Sennaar, or found by digging in the sand where it is making its way to its proper level the sea, after falling down the side of the mountains after the tropical rains. This plague appears indiscriminately in every part of the body, but oftenest in the legs and arms. I never saw it in the face or head; but, far from affecting the fleshy parts of the body, it generally comes out where the bone has least flesh upon it.
