OCCLUSION OF SUTURES 
In none of the specimens at hand can be detected any premature 
occlusion, though in this respect it is impossible to be certain as to 
the temporo-occipital articulations. Unfortunately, there is no pos- 
sibility of giving the exact relation of age to the occlusion in any of 
the sutures; all that it is possible to determine is their relative involve- 
ment. The order among the males is S-C-TO-L;1 that in the females, 
TO-S-C-L. It is plain that occlusions in the coronal and tem- 
poro-occipital sutures are almost as early and frequent as those in 
the sagittal, while those in the lambdoid are decidedly later. As to 
locality, the coronal suture occludes first below the temporal ridges; 
in the sagittal the commencement is most frequent, as usual, about 
obelion; in the lambdoid it is irregular; while in the temporo-occipitals 
in the Munsee it advances generally from the anterior or basal 
extremity of these sutures backward and upward.

WORMIAN BONES 
The frequency of Wormian bones in any given series of skulls, 
while a factor of no great importance, is always of some interest. 
It is certain that in this respect there is a wide difference even in 
different groups of the same people, such as the Indians. Among 
the Munsee, as already mentioned, we find a remarkable scarcity of 
these ossicles, especially in the males. Not only are the Wormian 
' S=sagittal; C=coronal; 7O=temporo-occipital; L=lambdoid.
