9, Vertical Projection or Height of the Head. — The vertical distance 

 from the vertex of the head to the under-surface of the chin is as 

 follows : — 



10. Vertical Length from Vertex to MoiUh. — This is measured to the 

 line of junction of the upper and lower lips, and corresponds to the junc- 

 tion of the upper and lower incisor teeth : — - 



By subtracting this measurement from the former the A'ertical depth 

 of the chin is obtained. Using the corrected means of the two measure- 

 ments for this purpose, the depth of chin in the males is -iS-^ mm., and in 

 the females it is 40"8 mm., or 2'1 and 2'5 per cent, of their statures. 



11. Cranial Height. — This is represented by the vertical length from 

 the vertex to a point opposite the middle of the tragus, which corresponds 

 very closely to the upper border of the external auditory meatus. It is 

 as follows : — 



14. Proportions of the Head. 



(a) Cejjhalic Index. — The proportion of the breadth of the cranium to 

 its length varies in the males from 69-6 to 87, and in the females from 

 72-6 to 86-6.
