are very conceivable, if the Reader has the leail 

 Notion of Hydrojlaticks. 



I could, under this Head, account for the diffe- 

 rent Changes Bodies undergo under a State of Cor- 

 ruption, which is one Species of Fermentation. 

 But with all thcfe Requifites to this inteftine Mo- 

 tion of the Bodies, very little thereof can take 

 place in circulating Liquors, fuch as the Blood, 

 <Jc. How much foever this Term therefore is 

 made ufe of to account for feveral Appearances in 

 Animals, it muil be from mere Ignorance, or on- 

 purpofe to deceive. For thus far only can their 

 Juices be capable of Fermentation, as they are re- 

 mitted in their circulatory Motions enough to make 

 the natural Attractions of their Particles greater, 

 than the Force by which they are impelled or driven 

 forward, which cannot be but where they are almoll 

 entirely flopped. And it is therefore in the larger 

 Glands only, that the feparated Juices may undergo 

 fome Motions of this kind, fo as fometimes to be 

 changed thereby from their natural Properties : 

 But the Blood ( while in its Circulation ) cannot 

 undergo fuch Influence, becaufe the Velocity of its 

 Parts, from the impelling Force, is too great to let 

 them obey their Attra(5tions of one another. Hov.' 

 remote from Truth then muft thofe Reafonings 

 be which are built upon fach a Foundation, I mean 

 fuch as build their Faith upon imaginary Notions of 

 the Blood's being in a Ferment, (as the commoe 

 ExprefTion goes j) and how hazardous muil a Prac- 

 tice be which flows from fuch a Theory ? 



I have been more tedious with relation to the. 

 aforefaid Term than ordinary, becaufe it will, I 

 hope, fave me farther Trouble in the Sequel of 

 this Book, when I come to treat of Fevers, which 

 (according to the comm„on Notion) are occafioned 

 through a Fermentation in the Blood. Therefore I 

 ^beg the Reader will excufe the Prolixity : But to 

 return.
