In figs. 27 and 28, the similar areas have been applied to 

 illustrate the functions of the human brain. Here, the results of brain- 

 disease in man serve as means of verifying the conclusions which 

 have been arrived at from experimentation on lower animals. The 

 figures indicating the areas on the brain of the monkey, have a cor- 

 responding significance on the brain of man. By way of briefly

testing the correctness of the physiologist's views, the history of one 

 region may be noticed. 



The regions 9 and 10 in the brain of the monkey are found to be 

 associated with movements resulting in opening the mouth and with
