* Arrangement of cases based on Facial Angle. 
+ The “subnasal point’’ of the writer is the lowest point on the inferior border of the nasal aperture 
on the left side: it is the point from which the height of the nose is measured. 
same method as that of the present writer and almost simultaneously 
with him; but no comparisons are as yet available in regard to the 
alveolar angle. It appears from Rivet’s data that among modern 
white adults the average of the facial angle, as herein defined, ranges 
in round numbers from 70.5° to 73°; among the negroes, the mean 
of Rivet’s series gives 68.5°; among several groups of American 
Indians it was 68° to 71.5°. Rivet calculated his indexes mathemat- 
ically and with the help of an ‘‘abaque,”’ while the writer obtained his 
results by the direct (graphic) method, which, for small series of 
calculations and used with precision, seems to him preferable, although 
the results are probably quite comparable. By this method the writer 
obtained on the Arkansas and Louisiana crania, previously reported, 
averages ranging for the facial index from 70° to 74° for the males, 
and_68° to 70° for the females; while the alveolar angle gave the 
average of 55° to 60° in the males, and 51° to 53° in the females. 
The Munsee crania give the rather high average of 73° for the males 
and 74° for the females, with respect to the facial angle, and 59° in 
the males with 57° in the females for the alveolar angle. These
