Dr. Cullen arranged all the difeafes of the human frame 
under four claffes; the firf containing the “ Pyrexiz,’”” or 
all thofe affeGtions which are a febrile; the fecond, 
«¢ Neurofes,”? or affeGtions of the nervous fyftem, that is, 
s¢ diforders of fenfe and motion,” cleseatiently of primary 
fever or local difeafe ; the third, ‘* Cachexiz,’’ or thofe dif-

Dr. Cullen’s ee clafs, Pyrexte, is fubdivided te five 
orders: the ji, which contains the fevers propery fo 
called, or idiopathic pees of which there are two fetions, 
the intermittent, and continued. Of the intermittent fevers, 
on, or the continued fevers, including three genera, fy- 
nocha, or inflammatory fever, typhus, and fynochus, com- 
prife alfo a great number of febrile affe€tions, which have 
been defcribed under various names by authors; but perhaps 
even Dr. Cullen’s divifion of the eased might be leffened.

Dr. Cullen’s fecond clafs comprehends the «* Neurofes,”” 
or “affections of the faculties of fenfe and motion, unac- 
companied by any idiopathic fever, or local difeafe.”” This 
clafs contains four orders, Comata, Adynamiz ze, Spafmi, and 
efaniz. It muft be admitted, however, that fomewhat of 
hypothetic opinion has been engaged in the diftribution of 
the genera and {pecies of this clafs; feveral of which, ef-
