An interesting feature in regard to the patella is the occasional presence of 
the vastus externus notch, 7. e., a more ог less marked defect in the border of the 
bone in the locality of the vastus externus insertion. This notch, which is seen 
rather frequently in Egyptian bones, and is also met occasionally among the 
whites, is present in more than half the male specimens and in more than a thi 
of the patella of females. It is, however, seldom pronounced, the majority of the 
bones showing only traces of the feature. 
The patelle of male skeletons 255.111 and 255.222, Louisiana, show each an 
extraordinarily developed apex.
