MENTAL FACULTIES. 43 



thicker the cortex and more numerous 

 and deep the folds, the larger is the mind. 21 



The frontal lobes are really the highest 

 part of the brain ; the brain being doubled 

 over forwards. The grey matter of the 

 frontal lobes is therefore the most highly- 

 developed protoplasm there is. It must 

 be of an exceptionally fine quality in such 

 brains as those of Messrs. Chamberlain 

 and Asquith ; perhaps a little less fine 

 but more in quantity in such as those of 

 Lord Rosebery and the late W. E. Gladstone. 

 Mind is not a single power ; it is made 

 up of groups of faculties. The grey matter 

 of the lower and back parts of the hemis- 

 pheres serves the lower or animal faculties ; 

 and that of the upper and front parts 

 serves the moral and intellectual faculties. 

 The cerebellum has nothing to do with 

 the higher mental functions. 



The logical conclusion to be drawn from 

 these facts is that the protoplasm of the 

 grey matter of the nervous system, especially 

 that of the bra n, is the source of the pheno- 

 mena called mind, just as the protoplasm 

 of the general system is the source of the

 We do not know mind apart from brain." DALLINGER,
