Publisher's Synopsis
Excerpt from Proceedings of the Academy of Natural Sciences of Philadelphia, 1893
Dr. Allen assumed that the coarse food of savage and semi-savage people caused the jaws even in an edentulous condition to be used actively in the act of mastication, while the more carefully prepared food suitable to the aged of civilized people enabled the jaws to have comparative rest, and hence the mechanical conditions which pre determined the localization of new structures were not active. The speaker concluded that the series of observations strengthens the position taken that the same forces which differentiate the kind of teeth operate in fashioning the shape of th'ejaws, even after the loss of the teeth.
