Text-figure 36 represents the distance from the orifice of 

 the auditory meatus to the nasion (pi. 35, fig. 3, O-D). The 

 range for this measurement is much greater than for the 

 bregma measurements, being from 103 mm down to 44 mm 

 or as 2.34:1, against the proportion of as 1.78:1 found for the 

 bregma series. When arranged in the same sequence as for 

 the meatus-bregma measurements, the measurements from 

 the auditory meatus to the nasion also show much greater 

 irregularity. Some skulls with a short distance between 

 meatus and bregma show a much greater distance from

meatus to the nasion. This is shown in a striking manner 

 by comparison of the measurements in the right half of the 

 two figures. One of the longest recorded measurements from 

 meatus to nasion occurs in a skull with a shorter than average 

 meatus-bregma distance. The two charts are in general but 

 irregular accord and there are wide individual discords. 



The distance from the auditory meatus to the anterior 

 end of the internasal suture (pi. 35, fig. 3, O-E) supplied 

 the measurements for text-figure 37. These measurements 

 show an almost total lack of relative agreement with the
