560 REPORT ON А COLLECTION OF CRANIA FROM ARKANSAS. 
Stze.—The skulls under examination are all of rather low capacity, when 
compared with whites, but can not be said to be exceptional for Indians, particu- 
larly for those of moderate stature, which in this case is indicated by the usual 
small lumen of the foramen magnum, as well as by a few of the long-bones sent by 
Mr. Clarence B. Moore to the Army Medical Museum (a right male femur among 
these measures 41.1 em.). The next table gives a number of determinations which 
have relation to the size of the skulls; it will be seen that it is of importance to 
learn, in connection with the external measurements, also the approximate thick- 
ness of the bones that form the cranial vault, to be enabled to judge with some 
accuracy as to the capacity. Тһе thickness of nearly all of these skulls 18 above 
the average in whites, though agreeing with that usual in the Indian.

The facial parts of these skulls gave measurements which are grouped in the 
next tables. It is seen that the upper facial height is in most of the instances 
quite considerable. This is due to a relatively great development in height of the 
upper alveolar process, which assumes really exceptional proportions in No. 249,916. 
The total facial height is less pronounced, due to a relative lowness of the inferior 
maxilla. The breadth of the face is throughout moderate. The nasal index is
