of the animal. This increasing curvature is accompanied 
with increasing expansion of the roof bones of the skull and 
arrest of the basal bones: thus in the human subject the roof 
bones are expanded far more than in any other animal, while 
the basal bones are crowded and even fused together by their 
position in the concavity of the curve of the cylinder. The 
human curve is not complete in infancy ; for, as the present 
writer has elsewhere shown, it goes on increasing for several 
years after birth: it is also greater in the higher than in the 
lower races of mankind. ‘This curvature is an important 
means of increasing the space for the cerebral hemispheres, 
by lengthening the roof; and it does so most effectually when 
accompanied with the other means which Nature uses to 
expand the cranium, namely, increase of vertical and trans- 
verse diameter of the cylinder. 
Farther, before returning to the question of foreheads, it 
must be pointed out that the position in which the head is 
articulated with the neck differs in different persons, accord- 
ing to the weight of the fore and back parts, so as to pre- 
serve balance. This is best seen in the process of growth, 
for the forehead and face have the smallest proportional de- 
velopment in young children; and as they become large, the 
head is tilted farther and farther round on the top of the 
vertebral column, so as to throw more weight behind the 
point of support, to balance the weight in front: and this 
tilting takes place to a much greater extent in men than in 
Women, because in women the face and forehead remain 
proportionally lighter. 
From the foregoing considerations it must be apparent to 
every one that loftiness of forehead results from general 
height of the whole skull, and that the apparent form of the 
forehead is very dependent both on the amount of total 
cranial curvature and on the balance of the head on the ver- 
 tebral column. The deceptiveness of mere general appear- 
ance may, perhaps, be best illustrated by noting how people 
speak of the large foreheads of children. The frontal emi-
