that the brain mass measured between 1 350-1400 c.c, 
but when we employ the indirect method and calculate 
the capacity from the diameters of the skull — using the 
Lee-Pearson formula — a capacity of 1500 c.c. is obtained. 
In actual size of brain, the Galley Hill man did not differ 
materially from modern men. The cast of the brain, 
which Mr F. O. Barlow made from the skull, shows that, 
so far as concerns the convolutionary pattern, the Galley 
Hill man was not inferior to the average modern 
European. The areas or lobes which are specially

concerned in speech and in movements of the limbs

The question of speech naturally leads our inquiry to 
the lower jaw — particularly to the region of the chin. 
Fortunately, the greater part of the left half of the lower 
jaw, and the whole of the region of the chin, were 
recovered. There are no Neanderthal marks at the 
symphysis of the jaw : the markings which indicate the 
origin of the chief muscles of the tongue are shaped and
