SKULLS OF ESKIMO CHILDREN
A special effort in our work has been made to secure well-preserved skulls of children. As elsewhere, so among the Eskimo, more children die than adults, but conditions are not favorable for the preservation of their skeletal remains. Most of the bones are done away with or damaged by animals (foxes, dogs, mice, etc.), while others decay, so that generally nothing remains of the youngest subjects and but a few bones and a rare skull of the older children. The total number of such skulls in our collection now reaches 25. They are all of children of more than 2 but mostly less than 6 years old, and are all normal specimens. The principal measurements of their vault—a study of the face is a subject apart and needing more material—are given in the following tables.
