CHAP. X.] CIRCULATION IN THE BRAIN. 299 



2. That, consequently, general or local bleeding will exert the 

 same kind of influence upon the circulation in the brain, as in other 

 organs, so far as relates to diminishing the quantity of blood in it. 



3. But that the brain is liable to suffer from the loss of blood in 

 a different way from other viscera, inasmuch as copious bleeding 

 may occasion serious disturbance in the functions of the brain by 

 lessening the force of the heart's action, and thereby depriving the 

 brain of that amount of pressure on its vascular surface which 

 seems essential to its healthy action. 



4. That the depression of the heart's force, from any other cause, 

 is capable of producing similar cerebral disturbance for the same 

 reasons.
