561. Although the brain is the seat of emotion, reason, and sensation, 

 it is of itself non-sensitive, as portions of it may be cut away with 

 little or no effect. I remember a case where a groom was thrown 

 from a horse, and kicked on the side of the head, just above the left 

 ear ; the skull was driven in, and a portion of the brain protruded i^ 

 inches. It could be handled with the fingers without causing the 

 patient any uneasiness, yet, if his lips were touched, the body was 

 thrown into frightful contortions ; he bemg at the time semi-conscious. 

 The protrudmg portion was left alone, when it gradually receded, and 

 within a week had returned to its proper place, a splendid recovery 

 being made.
