have not refpeft to the part affe&ed, but to the particu* 
lar Dyfcrafy of the Spirits. 
After a fhort Account of UniverfalDifeafes in general, 
he treats of the Nature of Acute Fevers, and calls the. 
Ferment which occafions them aPoyfon>which he proves 
to be of a very fubtile Texture, tho we can't have any 
perception of it by any of our Senfes ; and therefore he. 
forbears to give any particular Defcription of it, but goes 
on, and (hews how clearly the Symptoms of Acute. ' 
Fevers (which all proceed either from the oppreffion of 
the Spirits, or a greater degree of Elafticity which They, 
acquire from the Imitation of the Poyfon ) may be ex- 
plain'd by his Hypothecs. Accordingly, he tells us how, 
it comes to pa(s,that Coldnefs of the external Parts, a quicks 
and weak Pulfe, and irregular Refpiration accompany,

known the Blood , Actually cold in the beginning of the,

Latitude, Shaking, Trembling, Tofling, Yauning, Gid- 
dinefs, Sicknefs at Stomach which accompany the firft. 
Stage , and why a new Fit of Cold and Shaking (if the. 
Fever be not intermitting) Ihould portend Co much Dan->

Stages of the Diftemper in the fame manner. He takes- 
notice how r it comes to pafs that Rheumatical Pains re-

ptoms which are in the Humours, namely, the Sym-v 
ptom of Cholera Morhm ', Diarrhaa, Vomiting, Thirft* 
Drynefs of the Skin, Rednefs and Thicknefs of Urine^ 
Gffc* Now theCaufe of this Fever being a Poyfon from 
whence all thefe Symptoms have their Original, it ought 
to be cur'd by its proper Antidote. He informs us alfb 
what is to be done when the Antidote will not take place * 
and when he difcourfes of the Crifis of thefe Fevers, he 
©bferves that Sweats are not the Crifis its felf, but a fign
