 regions are less capacious proportionately than in the male. The vertex in the female is 

 said to be more flattened, and the height of the skull consequently somewhat reduced. In

 of the styloid process, whilst in the female the corresponding border is described as being 

 rounder and more tubercular.

 us to pronounce with certainty on the matter of sex, it is the case that, taken together, 

 they usually justify us in arriving at a conclusion which, as a rule, may be regarded as 

 fairly accurate. In some instances, however, it is impossible to express any definite 

 opinion.
