it, and the edges were now and then touched with blue vitriol. By those means 

 granulations began to shoot from all sides, the sore filled up gradually, and a 

 cicatrix was formed. He had had smaller ulcers of this kind in other parts of 

 the scrotum before this time, which Mr. Bishopp said he had treated with the 

 same success. 



The man was rather thin than fat, and might be about 50 years old. His 

 abdomen seemed rather empty, and appeared drawn in towards the spine ; yet I 

 do not think, that any of the intestines had descended into the scrotum, or if 

 any had passed down, the annuli of the abdomen must have been so dilated as 

 not to occasion the least obstruction in them ; for he never had, to my know- 

 ledge, any of those complaints or symptoms which attend ruptures. Besides, 

 ruptures are not very common among the blacks about Senegal ; indeed I can 

 say, that I never saw one of them. 



This man, it seems, had been purchased up the river as a slave, when he was 

 about the age of puberty, and brought down to Senegal, where he was kept as a 

 house-servant by an opulent inhabitant. He was for some years healthy and 

 well ; but afterwards his testicles began to swell insensibly, without inflamma- 

 tion, pain, or any other inconvenience. They increased gradually, though 

 slowly, and became some years after of such a bulk, that he was neither able to 

 walk nor perform his usual work. That he might however not be quite idle, as 

 he was otherwise a stout and able fellow, he used to cut bars of iron into pieces 

 of a foot long, which bear a certain price at Senegal, and go among the blacks 

 like current money. This he could do sitting with a chisel and hammer, and a 

 small anvil placed before him on the ground, his legs bent under him, and the 

 scrotum resting on the ground. Mr. Bishopp had seen him perform this work 

 for many years ; at last however the scrotum increased to such a degree, that the 

 great bulk prevented him from doing it any longer. From the time that the 

 disorder had first begun to shew itself to the time I saw him, 25 years had 

 elapsed; he was alive when I left the island in February 1779, and may be so 



now. 



This man was the only one I ever saw afflicted with this disease at Senegal ; 

 but I am credibly informed, that it is endemial in a country which goes, among 

 the blacks at Senegal, by the general name of Galam, and of which this man 

 was a native. This country lies east of Senegal, at the distance of about QOO 

 English miles, and its inhabitants are called Bambaras. I have been told by 

 those inhabitants of Senegal, who go annually in the rainy season in a fleet of 

 small craft to Galam for trade, that this disease is particularly common among 

 the chiefs or noblemen of that country. 



When I was at Fort James in the river Gambia, for a short time in the year 

 1776, I was told by some Marahbuts, or Mahometan priests, of the Mandinga
