age of Algonquian female crania; the broken parietal gives it a 
deceptive appearance of narrowness. Its vertical index (72.5) 
resembles that of the West Chester skull, and is widely removed 
from those of the Burlington and Riverview specimens. The 
relative height is not notably less than that of the Massachu- 
setts series, in which the range of this index is from 67.8 to 8.5. 
The superior facial index could not be calculated in many cases 
because of the broken condition of the crania. The naso-malar 
index, which expresses the degree of projection of the interor- 
bital region, is quite uniform and within the limits of individual 
variation for the whole series. The racial averages given by

The orbital index is*higher in the Trenton skull than in the 
Eastern Algonquins, in only one of which is the index above 
90. In the shape of the orbit the New Jersey and West 
Chester skulls stand apart from the others and fall within the 
megaseme group. Unfortunately, the nasal index cannot be 
calculated for the Trenton skull; the West Chester and River- 
view crania both have lower nasal indices than the skulls from 
the region north and west of them. The evidence of the re- 
maining indices is inconclusive and comment is unnecessary. 
Condition of the New Jersey Crania.— The sutures of the 
Trenton skull are obliterated, and its thickness is sufficient 
to insure its preservation where an ordinary skull would be 
crushed to fragments. However, it does not present the 
appearance of having been rolled about for any length of time 
in the gravels; the left styloid process projects for a distance
