is true, can differences in the degree of curvature be cor- 

 related with other characteristics of the skull? In order to 

 answer such questions, these same skulls were charted for 

 eight other dimensions.

Text-figure 2. Sequence A. Zygomatic width. Group of seventy skulls ar- 

 ranged in sequence from greatest to least distance between the widest lateral 

 points of the zygomatic arch. 



Text-figure 3 represents the cranial widths of the skulls 

 (pi. 35, fig. 1, G) arranged in the same sequence as for zygo- 

 matic arch measurements, and these range from 65 to 45 mm. 

 In spite of the size differences among the skulls, the widest 

 cranial measurement is only 50% greater than the narrowest. 

 A comparison of this chart with that for zygomatic widths 

 shows no accord between the two. The thirty-second skull 

 in the cranial width series, for example, is among the widest
