liver ; that one process illustrates just as forcibly the influence of 

 a mysterious force or power as the other. 



The product of the liver, the bile, will vary according to the 

 size, quality, and condition of the organ and the forces acting 

 upon it ; and the same is true regarding the functional product of 

 the brain, the mind. Without liver there is no bile, and without 

 brain there is no mind. At least the physician only investigates 

 mind, which is a functional product of brain. The analogy, how- 

 ever, between brain and liver does not hold throughout, because 

 after birth, and from that period to maturity, and indeed while

life lasts, the brain is ordinarily exposed to impressions made by 

 an ever-changing environment, while the environment of the 

 liver remains practically uniform. 



It may be conducive to a clear understanding of the medical 

 view of mind, and therefore of responsibility, to examine objec- 

 tively the organ itself, and briefly the manner in which its func- 

 tions are studied by the j^hysician. I need hardly remind you 

 that the brain is a double organ, and therefore only one half of it 

 need be shown. 



Figs. 1 and 2 are exact representations of the outer and mesial 

 surfaces of the human brain.
