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 bones
scarce in this series, but they are also invariably small. This
scarcity may in all probability be regarded as a sign of the absence of
all disturbances, developmental as well as pathological.
