1. 1 HAT is the natural state of the human body 

 wherein all parts of it duly perform their natural ope- 

 rations. The chief of these are, the circulation of the 

 blood, respiration, chylification, nutrition, and mo- 

 tion. 



2. That the blood circulates through the whole body 

 appears hence. Any of the arteries being tied with a 

 thu ad will swell and beat between the bandage and 

 the heart, but grow flaccid between the bandage and 

 the extremities of the body. And if the artery be cut 

 between the bandage and the heart, blood streams out 

 even to death; but if it be cut between the bandage 

 and extremities very little blood comes out. The vital 

 blood, therefore, flows from the heart, through the 

 arteries, toward the extremes of the body, and still 

 out of a wider part into a narrower, out of the trunk 

 into the branches.
