No traces of this difeafe are difcoverable in the writings either 

 of the Greeks, Romans or Arabians. 



BoNTius, in his account of the medicine of the Egyptians, 

 mentions the cafe of his friend Cavallerius, who was feized with

 a flight diforder, in which the fkin is afFedted, not with fpreading 

 veficles, but with fmall puftules. He feems alfo to confound 

 with pemphigus fome other erythematous afFedions ; for he fays 

 that thefe watery puflules frequently precede the eruption of the
