malignant confequences of the venereal difeafe. The {mall 
fwellings or eruptions, when fqueezed, very often yield

health, faving the pain the ulcers give him, and the {till 
greater uneafinefs of mind which he fuffers from the fpoil- 
ing of the f{moothnefs of his fkin; for all the nations in 
Africa within the tropics are wonderfully affected at the 
{malleft eruption or roughnefs of the fkin. A black of Sen- 
naar will hide himfelf in the houfe where dark, and is 
not to be feen by his friends, if he fhould 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 re- 
lief. Scars and wounds are no blemithes; and I have feen 
them, for three or four pimples on their bracelet arm, fuffer 
the application of a red-hot iron with great refolution and 
conftancy.

in Europe. The fecond is completely and fpzedily cured by 
antimonials. | 
Tue next complaint I fhall mention, as common in thefe 
countries, is called Farenteit, a corruption of an Arabic word, 
which fignifies: the worm of Pharaoh; all bad thin gs being 
by che Arabs attributed to thefe poor ne gs, who feem to be 
looked upon by pofterity as. the evil genli of the country 
which they once governed.
