Ill THE ENGIS SKULL 167 



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 (6), 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 and elegantly arched 

 in the transverse direction, and that the transverse 

 diameter was a little less below the parietal pro- 

 tuberances, 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 con- 

 tour, 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.
