 the several parts of the facial skeleton in an effort to deter- 

 mine whether these measurements are related. 



Comparisons of the lengths of various facial parts and 

 regions of the skull. The charts plotted for this series of 

 skull measurements show the lengths of different parts of 

 the facial skeleton all placed in a sequence based on the

value of palatal lengths, from the specimen with longest bony 

 palate down to the one with the shortest. These palatal length 

 measurements, shown in text-figure 20, range from 122 mm 

 to 36 mm, the longest being to the shortest as 3.4:1. A curve 

 drawn along the top of the lines in this chart is fairly smooth 

 and steep. Five other measurements of length on various
