    do not greatly differ. The advance is in complexity rather than in size. From our present point of view, however, the most inter- esting number isthe 9,300 sq. m. m. of the Chimpanzee. Thi# number is intercalated amongst those that refer to the brains of the ape-men. The relative positions of the adult human being, the anthropoid ape, and the abnormal man, are well shown by the three numbers given at the end of this table. Taking 100 as representing the total brain-surface of the white race, 44*6 represents the average of the total brain-surface in such microcephali as have been examined, and 33 the brain- surface of an average anthropoid ape. The difference number (100 — 44*6 = 55*4) between the two kinds of men is nearly five times as great as the difference number (44*6 — 33 = 11 *6) between the lower man and the ape. Brain Capacity.
