304 ON SOME FOSSIL REMAINS OF MAN 



The lines of fracture which remain between the coad- 

 justed pieces of the skull, and are faithfully displayed in 

 Schmerling's figure, are readily traceable in the cast. The 

 sutures are also discernible, but the complex disposition 

 of their serrations, shown in the figure, is not obvious in 

 the cast. Though the ridges which give attachment to 

 muscles are not excessively 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 

 extreme breadth, which corresponds very nearly with the 

 interval 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. If a 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. 22), to the occipital protuberance (ft), 

 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. 23, 

 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. 23, B) shows that the roof of the 

 skull was very regularly and elegantly arched in the trans- 

 verse 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 pro- 

 tuberance, 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. 



The supraciliary prominences or brow-ridges (on each 

 side of a, Fig. 22) are well, but not excessively, developed, 

 and are separated by a median depression. Their principal 

 elevation is disposed so obliquely that I judge them to be 

 due to large frontal sinuses.
