648 . REPORT—1890. 
The third form of cranium is produced by combination of frontal, 
occipital, and lateral pressure. In crania of the southern tribes of this 
region, evidence of a pressure upon the lambda may be seen; but the 
forehead is at the same time flattened, and the total distance from 
glabella to lambda increased, the occiput being inclined backward. There- 
fore the occipital index of these crania is very large. The Koskimo crania 
are compressed on all sides, and therefore very long, the axis of the 
cranium being depressed. 
I give here a series of measurements of crania, showing the typical 
deformations. I have to thank Professor F. W. Putnam, Director of the 
Peabody Museum of American Archeology of Cambridge, Mass., for his 
kind permission to me to describe the three Chinook crania.
