MOTION OF THE HEART AND BLOOD 



as the lungs, but outlives them and continues to 

 beat. The left ventricle and the arteries continue 

 to send blood to the rest of the body and into the 

 veins, but, receiving none from the lungs, they soon 

 become empty. 



This fact awakens not a little belief in our posi- 

 tion, since it can be ascribed to no other reason 

 than what we have proposed. 



It further appears that the greater or more vehe- 

 mently the arteries pulsate, the quicker will the 

 body be exhausted of its blood in a hemorrhage. 

 Hence in fainting or alarm, when the heart beats 

 slowly and feebly, a hemorrhage is reduced or 

 stopped. 



This is also why one cannot draw forth by any 

 effort more than half the blood by cutting the jugu- 

 lar or femoral veins or arteries in a dead body after 

 the heart stops beating. Nor may a butcher succeed 

 in bleeding an ox after hitting it on the head and 

 stunning it, if he does not cut its throat before 

 the heart stops beating. 



Finally, it may now be suspected why no one so 

 far has said anything to the point on the place, 

 manner, or purpose of the anastomosis of veins 

 and arteries. I shall now discuss this point.^ 



* But he doesn't. This point is quite forgotten. Further evidence 

 of assembling the treatise from notes written at different times.
