Thefe are hard convex tubercles, with an uneven 

 furface, of the fize of warts, and of a black 

 fufcous color. When cut tranfverfely, their 

 internal part appears to be full of minute hol- 

 low fphsrules, imbedded in a dark fufcous 

 fubftance, and replete with a black povvder. 



The tubercles are commonly diftind, but are 

 fometimes confluent.

 ranked- under a nev/ gemis. 



The tubercles are fometimes found externally of 

 ? ferrugineous color.
