The Kirghiz are the most brachyskelic people of Central Asia 

 according to all available literature, and invariably possess higher 

 relative sitting-height indexes. 



Average data for stature and cephalic-index correlations was tabu- 

 lated for other Central Asian groups, and an apparently reverse 

 phenomenon was observed — i.e., greater stature was accompanied by 

 lesser cephalic index. In order to investigate this contradiction, a 

 small group of brachycephalic peoples was taken (Kirghiz, Uzbek, 

 Kara-Kalpak, Jews, and Arabs of Central Asia), and the coefficient 

 of correlation was calculated for the group. This was insignificant 

 but negative (R= —0.076 ±0.199), ^nd typical for intertribal correla- 

 tion of stature and cephalic index pointed out by Pearson. 



The positive correlation among the Tajiks seemed to indicate the 

 intratribal character of the difference, which would seem to strengthen

Ginzburg's premise that the Tajiks belong to a single group, fairly 

 homogeneous in character. 



An attempt was made to verify this conclusion by calculating the 

 individual correlation data for the entire group and for the regions. 



Cranial deformation was found to be a significant factor. In the 

 presence of occipital deformation the correlation was found to be 

 insignificant but invariably positive. 



In the presence of undeformed occipita the correlation is negative, 

 and the coefficient of correlation is fairly sizable. Thus, it is clearly 

 seen that the cephalic index decreases with the increase of stature, 

 but that occipital deformation entirely obscures these relationships. 



In comparing cephalic index with stature it may be seen that the 

 decrease of cephalic index progresses until tall medium stature is 

 reached, but that in the presence of high (170.0 cm.) stature cephalic 

 index increases both in the case of deformed and undeformed occipita. 



The problem of interdependence of cephalic index and stature is 

 an independently important problem of ontogenetic development, of 

 particular interest in connection with the study of deformed occipita. 



Facial dimensions and indices. — Morphological face height (nasion- 

 gnathion) (M= 126.92) is great, but in comparison with the facial
