The more precocious, such as 1 (the area concerned

with the sense of touch), 4 (the visual receptive area), and 5 (the acoustic area) are just as well developed in the ape as in man. The intermediate areas (6 to 30) are also moderately large in the ape. But the latest areas to mature (34, 35 and 36) are enormously bigger in the human brain. The only contrast between the human and the simian brain is that certain areas in the brain of man are enormously bigger than the corresponding areas in the brain of the ape (Figs. 2 and 3). The structure of these corresponding parts
