cranium, and is thus proportionally heavier in woman than in 
man, and, if allowance be made for the greater development of 
weight of the skull in Parisians, Europeans generally, and Hin- 
09s, than in negroes or other inferior races, and that in a new- 
born infant both cranial capacity and weight of brain, as compared 
with weight of skull, are three times that of the adult. 
The weight of the mandible, compared with that of the skull, 
is greater in man than in woman, so that in this character civilized 
is so complicated by the relations between the brain and the 
motor, nutritive, and, it may be added, reproductive functions, 
and also by those between it and the size and age of the indi- 
vidual, that it is impossible, with our present knowledge, to judge 
with any certainty of the intelligence of an individual by the, 
Weight of the brain, the capacity of the cranium or any relation 
of these to the entire skeleton or portions of it. Yet some of the 
relations established seem to point the road to further knowledge 
of this most abstruse of subjects.
