LIFE AND DEATH. 359 



shall be said are nothing less than words, we will deduce 

 these three intentions to ten operations. 



1. The first is the operation upon the spirits, that they 

 may renew their vigour. 



2. The second operation is upon the exclusion of the air. 



3. The third operation is upon the blood, and the sangui-

 comprise experiments and observations, but also counsels, 

 remedies, explications of causes, assumptions, and what 

 soever hath reference hereunto.

 Youthful, and renew their Vigour. 



The History. 



1. The spirits are the master workmen of all effects in

 instances. 



2. If any man could procure that a young man s spirit 

 could be conveyed into an old man s body, it is not unlikely 

 but this great wheel of the spirits might turn about the 

 lesser wheel of the parts, and so the course of nature become 

 retrograde. 



3. In every consumption, whether it be by fire or by age, 

 the more the spirit of the body, or the heat, preyeth upon 

 the moisture, the lesser is the duration of that thing. This 

 occurs every where, and is manifest. 



4. The spirits are to be put into such a temperament and
