Contributions towards determining the weight of the brain in the different races of man

It would naturally be expected that great attention had been directed to the human brain, the organ of mental manifestation. Still little has been done to ascertain its relative magnitude in the different races of mankind. Opportunities for examining exotic brains are rare, and it is only by gauging the internal capacities of human skulls, and deducing the weight of the brain, that data can be obtained. The inferiority of this method is not so clear as has been assumed, since we are able to fix upon an unchangeable substance of definite specific gravity for the purpose of this gauging, whereby we compensate for the variable condition of the brain, depending upon disease and other causes, and the immediate occasion of death.
