CHAPTER VII. 



Brain Seat of Mind, Affections, Passions. Power and Action of 

 Mind limited by Power of Brain. Stimulation of Brain stimulates 

 Mind, and, on the contrary, Mind subject to Liabilities of Brain. 

 Impaired by Indigestion; by Excess of Eating; by Hunger. 

 Moral Feelings affected by Stomach. Effect of Cheerfulness.

 ear the organ of hearing, so the brain is the organ of percep-

 there. is no sight without it. The ear is not hearing, though

 though there is no mental operation without it. 



803. The brain being the only instrument with which 

 the mind plays^ here, they are indissolubly connected to-

 brain can go. Whenever the brain is weary, the mind is
