axes such as stature and width of shoulder. Other diameters in different 
axes, such as length and width of head, height and width of face, and height 
and width of nose show a lower degree of correlation. The differences 
in degree of correlation of two diameters between full-bloods and half- 
bloods are not very great. On the whole, it does not seem as if inter- 
mixture had seriously affected the degree of correlation. In the instance 
of face width and head width the correlation seems to be increased in the 
half-bloods. 
The distribution of face width among the one-fourth Indians, two- 
fourths Indians, one-half Indians, and three-fourths Indians indicates 
that the inheritance is alternating. The mixed individual tends to in- 
herit either the Indian or European type of face, intermediate types being 
of relatively rare occurrence. A high degree of correlation between width 
of face and width of head was found in the mixed group. Individuals 
with a narrow head had a tendency to inherit also the narrow face and 
vice versa. A summary of the anthropometric results will be found in 
table I and of the correlations in table II. 
A detailed report will be published in the Anthropological Papers of the 
American Museum of Natural History, vol. 23, part 3.
