THE GROWTH OF THE BRAIN. 



TABLE 48 (SIMILAR TO TABLE 47). BASED ON THE RECORDS 

 OF CALORI. 



The extent of the cortex was calculated geometrically. The 

 records are separated according to sex and shape of head. B. 

 Brachycephalic. D. Dolicocephalic. 



TABLE 49 (SIMILAR TO TABLE 47). BASED ON THE RECORDS 

 OF THE PERCENTAGE OF WATER BY DE REGIBUS. FOUR 

 CASES. ITALIAN BRAINS. 



So far as these figures show anything, it is that the 

 larger brains have a larger area of cortex ; and further, 

 that as here given there is a very fair concordance 

 among the results obtained by the different observers. 

 When it can be stated in what manner the total brain- 

 weight is to be interpreted, it will be possible also to say 

 what significance is to be attached to the extent or 

 weight of the cerebral cortex. In the meantime it is 

 interesting to note that of the total area of the cortex,
