Meafles and Small-Pox, with the African or true 
Plague. — From hence likewife proceeds the rank 
Smell, or peculiar Fretor, of dark-skinn'd People. 
Coroll. VII. This Acrimony of the perfpirable Hu- 
mours, with the Thicknefs arid Denfity of the 
Skins of black and tawny People, or Imperfpira- 
bility of their Bodies, makes them fubjedt to many 
fevcre cutaneous Difeafes, accompanied with a Con- 
tagion, which white People never feel, but by 
Infection from them 5 and then thefe Difeafes 
appear in other Shapes, with milder Symptoms, 
than in the dark-skinn'd People which breed them.— 
Thefe Difeafes, which I have obferved among them, 
may be referred to the Elephantiafis Grsecorum , 
or Lepra Arabum , two Species of which are called, 
the laws, and the Joint-Evil , with fome others, 
not named, appearing in obftinate fubcutaneous 
Ulcers.— -But the Elephant iafis Arabum, to which 
the Negroes are likewife fubjedt, is not a cutaneous 
Diftemper, as has been thought, but a peculiar Kind 
of Cachexy, accompanied with an atrabilious Ca- 
cochymy, as in thofe afflitted with the Haemor- 
rhoids ; that being much the fame Diftemper in 
the Legs, as this is in the Hrcmorrhoidal Veins. — 
The peculiar Difeafes of white People analogous 
to thefe of the Blacks, and which the Blacks never 
have, are the Lepra Grrecontm, at lead with fur- 
furous Defquammations, theTtch, Scurvy, ElTere, 
and fome fmaller ones of that Kind. — This cuta- 
neous Malady of the Negroes, called the Taws, 
laid the fil'd Foundation of the Lues Venerea ; 
which became to differ from it only by the Part 
affe&cd.
