three charts (text-figs. 40, 41 and 42), and indication of a 

 slight correlation between the anterior cranial measurement, 

 meatus to nasion, and the other two of this sequence which 

 involve muzzle length. 



A comparison of these figures warrants the statement that 

 in general a long anterior cranial region is associated with 

 a long facial skeleton or a long muzzle. There are, however, 

 wide exceptions to this generalization. In certain types of 

 skulls a long anterior cranium is contrasted with a much ab- 

 breviated facial skeleton. The specimen which gave the meas- 

 urements represented by the sixth line from the left in each 

 of the three charts is a striking- example of the association 

 of one of the longest crania in the series with two of the 

 shortest facial features. Numerous skulls of this type may be 

 detected in the group by comparing the corresponding lines 

 of the three charts. 



Obviously the distances from auditory meatus to the an- 

 terior nasal point and from the meatus to anterior dental 

 alveolus are closely correlated. This correlation in individual 

 detail may be accurately demonstrated by arranging the se- 

 quence of skulls on the basis of one of these measurements. 

 Text-figure 43 represents the sequence of measurements from 

 greatest to smallest distance from the auditory meatus to 

 the anterior end of the internasal suture. The range for these 

 measurements is from 176 mm down to only 45 mm, the 

 longest being almost four times the length of the shortest. 

 A very regular and steep decline is formed by the tops of 

 the lines in this figure. 



The measurements from the auditory meatus to the superior 

 dental alveolus are recorded in an identical sequence in text 

 figure 44. The range of measurements in this chart is from 

 200 mm down to 57 mm or as the ratio 3.5:1. This range 

 of measurements is not quite so wide as that represented 

 in text-figure 43, but on the whole the general outline of the 

 two charts is very similar. Yet even here we find small 

 individual deviations. Such differences among the elements
