 Same skull sequence as text -figure 45. 



Text-figure 47 represents measurements from the anterior 

 end of the internasal suture to the anterior superior dental 

 alveolus (pi. 35, fig-. 3, E-F). We have already referred to 

 the differences in the lengths of this measurement as being 

 chiefly responsible for the disagreements between individual 

 skulls in text-figures 43 and 44. Arranged in the present 

 sequence, these measurements, which involve practically the 

 total length of the floor of the anterior nares, show a general 

 correlation with the lengths of the anterior cranium, bregma 

 to nasion (text-fig. 45). But again it is seen that many wide 

 individual disagreements exist between these two measure-
