in the calculation of the cephalic index. The -^ -^ - index is then classified as

 80 to 84.9 

 85 and more.

Aurel von Torok's(68) classification is useful in determining the actual size 



of the skull and its length in connection with the index. He uses symbols 



length 



which are the initial letters of the three groups representing the three sizes of 



length and the three of width of the skull, namely, small, medium, and large. 



These will be symbolized by their English equivalents, s, in, and I as follows: 





s=narrow 

 (short). 



m=mocliiim. 



l=wide 

 (long). 



Greatest skull width varies 101 to 178 mm

Each skull is given a number, 1 to 82, which corresponds to its length in 

 millimeters; No. 1 = 143 millimeters and No. 82=224 millimeters.
