were from a more vigorous class of persons than is 

 ordinarily found in the hospitals of cities. Statistically, 

 the results arc satisfactory. They show the male negro 

 brain to be less heavy than that of the average white 

 soldier, and that in mulattocs (the father being white) 

 a mixture of less than half white blood gives a brain- 

 weight below that of the pure negro, whereas in those 

 possessing half or more than half white blood, the 

 weight of the brain is above that figure. 



Recently Gilchenko l has reported on the weight of 

 the brain in several transcaucasian races. The weight 

 was that of the entire tncephalon covered with pia, 

 and was taken without drainage. These results are of 

 especial interest as showing the wide variation which 

 occurs among races of the same region and fairly 

 similar in their culture.

The older tables, giving the weight of the brain in 

 sixteen Chinese (Crochley-Clapham), and in nineTurcos, 

 Algerian soldiers in the French army (Bischoff), arc 

 to be found in BischofFs HirngewicJit des MetiscJien.
