The second measurement was taken along the mid-dorsal 

 line from the nasion to the anterior end of the internasal 

 suture (pi. 35, fig. 3, D-E). This measurement is a direct 

 forward continuation of the one above. A comparison of 

 text-figures 45 and 46 shows practically no correlation. Strong 

 disagreements stand out all along the series in the two 

 figures. Two adjacent skulls which are closely the same for

bregma to nasion distances may be extremely far apart for 

 lengths of internasal sutures. The last two lines to the right 

 in each figure strongly emphasize this point; the bregma- 

 nasion distances for the two skulls differ by only 1 mm, while 

 the internasal suture length is 3.3 times longer in one of 

 these skulls than in the other. A number of other almost 

 equally wide divergencies between closely adjacent lines rep- 

 resenting internasal suture lengths can be seen.
