“ DIMPLES IN THE CHIN An oval, well-rounded chin is one of the most important elements of formal beauty, and is a characteristic trait of humanity; for man is the only animal that has a chin. Lavater distinguishes three principal varieties of chin: the receding chin, which is peculiar to lower races and types; the chin which does not project beyond a line dropped from the lips; and the chin which does project beyond that line. Of all parts of the face the chin has the least variety of form and capability of emotional expression. ”
