THE BRAIN OF FOSSIL MAN

once brings home to us the fact that a large brain is not 
the monopoly of modern man. Now, when we examine 
the track of the longitudinal sinus along the vault of the 
Neanderthal brain cast (fig. 156), we see many points in 
which it differs from a modern brain cast. In front, we 
see at first the same depression or groove between the 
frontal lobe — a depression in which the longitudinal 
blood-sinus lies. There appears, in front of the bregma, 
the median vascular elevation seen in brain casts of 
modern skulls. But behind the bregma the elevation 
ceases, and the narrow median ridge for the sinus appears, 
set in a depression or hollow between the raised marginal 
parts of the cerebral hemispheres. Just in front of the 
lambda the ridge caused by the longitudinal sinus shows
