ia Agues there is fome morbifick 

 matter of a vifcous or not eafily diffi- 

 pable texture 5 that is harbor'd in 

 tome part of the body , and requires 

 fuch a time to be made fluid and re- 

 folvablej the Cold Fits of Agues 

 need not be fo much admired as they 

 ufually are 5 fince, though juft be* 

 fore the Fit the fame parcel of mat- 

 ter that is to produce it were a&ually 

 in the body, yet it was not by rea- 

 fon of its clamminefs a&ually refol- 

 ved into fmall parts , and mingled 

 with thofe of the bloud, and confe- 

 quently could not make fuch a 

 change in the motion of that liquor 

 as is felt in the Cold Fit of an Ague i 

 ( for, of the further Change that 

 occaiions the Hot Fit, I am not here 

 to fpeak ) And in fome other Dif 

 eafes a fmall quantity of matter, be- 

 ing refolved into minute parts, may 

 be able to produce a great fenfe of 

 Coldnefs in fome part of a body, 

 which by reafon of the ftru&ure 

 cf that part may be peculiarly
