 effedl of inftindlive obftinacy and ignorance, 

 tranfmitted from fire to Ton; and is one of the 

 mod: palpable reafons than can be prodaced for 

 the frequent appearance and progrefs of this 

 complaint, vt^hether proceeding originally from 

 a hidden accumulation of external naftinefs or 

 internal impurity. 



As I mean however to give the explanation 

 of this difeafe the face of novelty, I fhall hint 

 only at the impoffibility of removing, from 

 under the loads of hair juft defcribed, the quan- 

 tity of dirt and extraneous matter that muft 

 inevitably lodge there, and continue to accu- 

 mulate without even a probability of extirpa- 

 tion ; and proceed to hazard an opinion, or 

 perhaps a fadt, that the proportion of fecreted 

 perfpirable matter, making its efforts here (as 

 elfewhere) for a natural difcharge, is obfl:ru6led 

 by the mafs or filth caked upon the furface, as 

 before explained; and becomes, in the courfe 

 of time, too vifcld zni. fuhfiantial io b^ again
