In this clafs, as the difeafe is complicated of 

 fever and eruption, the genus is defined from the 

 nature of each. To infcance, the Variola^ or Small 

 pox, is defined, " A difeafe attended with puf- 

 tules of an eryfipelatous, fuppu.rating, efcha- 

 rotic kind j at length drying off, and leaving a 

 cicatrix ; accompanied by a fever of the ardent, 

 and malignant kind, with head-ach and pain 

 ** of the loins." The term Puftula^ and the others 

 in this clafs, expreffive of the diflTerent kinds of 

 eruption, have their definition in another part of 

 the fyftem. Such as appear in the Morta, are 

 called Phly5!en^ ; in the Pedis, Anthraces^ or Bu- 

 hones *, in the Variola, Puftul^ ; in the Rubeola, 

 FapuU i in the Petechia, Siidamina, 



This clafs conftitutes the firft order of Dr. Sau- 

 vages's PHLEGMASIA, and the third of Dr. 

 Cullenh PYREXIA clafs. In- both, thefe genera 

 are preferved nearly alike, except that the M?r/^ 

 of LiNN^us is the Pemphigus of thofe authors, 

 and the Petechia is gonfidered by Dr. CuUen as only 

 a fymptom* 



Our author ftands alone in bringing the Syphilis 

 into the febrile exanthematig clafs. He thinks 

 himfelf juftified, by confidering it as attended, in 

 the advanced ftate at lead, by fever and eruptions. 

 It certainly however ranks better with the Im- 



PETIGINES.
