Comparison of the Same Skull Dimensions Arranged in 

 Another Sequence 



When the sequence of skulls is arranged on the basis of 

 a somewhat more significant measurement than that of meatus 

 to bregma, which was used in the preceding series, there is 

 a tendency toward closer agreement in the curves represent- 

 ing the various measurements. The sequence we are now to 

 follow is based on measurements from the orifice of the 

 auditory meatus to the nasion, an anterior cranial dimension.

Text-figure 40. Sequence K. Auditory meatus to nasion. Group of seventy 

 skulls arranged in sequence from greatest to least distance between these two 

 points. 



These measurements range from 103 mm down to 44 mm, the 

 extremes being to each other as 2.34 :1 ; the curve formed by 

 the lines representing these measurements (text-fig. 40) shows 

 a very regular and fairly steep decline. 



Text-figures 41 and 42 represent the measurements from 

 the auditory meatus to the anterior end of the internasal 

 suture, and from the meatus to the anterior superior dental 

 alveolus, respectively. The curves formed by the lines rep-
