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 possibility 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 involvement. The order among the males is S-C-TO-L;[43] that in the females, TO-S-C-L. It is plain that occlusions in the coronal and temporo-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.

[43] _S_ = sagittal; _C_ = coronal; _TO_ = temporo-occipital; _L_ = lambdoid.
