ling’s figure, are readily traceable in the cast. The sutures 
are also discernible, but the complex disposition of their serra- 
tions, shown in the figure, is not obvious in the cast. Though 
the ridges which give attachment to muscles are not exces- 
sively prominent, they are well marked, and taken together 
with the apparently well developed frontal sinuses, and the 
condition of the sutures, leave no doubt on my mind that the 
skull is that of an adult, if not middle-aged man. 
The extreme length of the skull is 7.7 inches. Its ex- 
treme breadth, which corresponds very nearly with the in- 
terval between the parietal protuberances, is not more than 
5.4 inches. The proportion of the length to the breadth is 
therefore very nearly as 100 to 70. Ifa line be drawn from 
the point at which the brow curves in towards the root of the 
nose, and which is called the ‘ glabella’ (a), (fig. 23), to the 
occipital protuberance (4), and the distance to the highest 
point of the arch of the skull be measured perpendicularly 
from this line, it will be found to be 4.75 inches. Viewed 
from above, fig. 24 A, the forehead presents an evenly 
rounded curve, and passes into the contour of the sides 
and back of the skull, which describes a tolerably regular 
elliptical curve. 
The front view (fig. 24 B) shows that the roof of the skull 
was very regularly aud elegantly arched in the transverse 
direction, and that the transverse diameter was a little less 
below the parietal protuberances, than above them. The 
forehead cannot be called narrow in relation to the rest of 
the skull, nor can it be called a retreating forehead; on the 
contrary, the antero-posterior contour of the skull is well 
arched, so that the distance along that contour, from the 
nasal depression to the occipital protuberance, measures about 
13.75 inches. The transverse arc of the skull, measured 
from one auditory foramen to the other, across the middle 
of the sagittal suture, is about 13 inches. The sagittal 
suture itself is 5.5 inches long.
