It cannot be said, therefore, that the greater length of the frontal lobe is a character of the Anthropoid Apes as contrasted with Brain of Goriila. Letters as in fig. 1. One cannot be convinced in spirit-preserved brains that the shrinkage has been uniform. It is doubtful, therefore, how far accurate measurements are of use.
