in THE ENGIS SKULL. 167 



shown in the figure, is not ohvious in the cast. 

 Though the ridges which give attachment to 

 muscles are not excessively prominent, they are 

 well marked, and taken together with the appar- 

 ently well developed frontal sinuses, and the condi- 

 tion of the sutures, leave no doubt on mv 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 protuber- 

 ances, is not more than 5.4 inches. The propor- 

 tion 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. 23), to the occipital protuberance (b), 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 toler- 

 ably regular elliptical curve. 



The front view (Fig. 24, B) shows that the roof 

 of the skull was very regularly and elegantly 

 arched in the transverse direction, and that the 

 transverse diameter was a little less below the pari- 

 etal protuberances, than above them. The fore- 

 head cannot be called narrow in relation to the rest
