herpes, both Scared and /finall ulcers; his words. are, ‘ phlyc-

contitting of or ( papule), and not of pultules: but it 
bviou at his definition of papula is not limited to the 
fame feate * which it is confined by Dr. Willan, but may 
include {mall veticles. He ftates that the papula differs from 
the puflule, ‘inafmuch as it does not fuppurate, but dif- 
charges a little moifture from its apex, and then becomes

eorred.: “ Herpes e

rae regs raro cru(taceas abeuntibus.”” (Sauvages 
Ord. 2. Genus 7.) The herpetic

itsinate in thin fea ruts.
