    small permanent double teeth, the bicuspides, appear; the upper teeth follow the same course; the four permanent cuspidati also be- gin to produce a fulness of the jaws between the lateral front teeth and the recent bicus- pides; these prominences enlarge, and the teeth advance; at the same time, the posterior temporary grinders show symptoms of falling either by decay, by discoloration, or by be- coming partially loose. It is now advisable to remove them, and, as they occupy a much greater space in the circle than the second permanent bicuspides, which are to succeed them, their extraction will also make room for the development of the cuspidati, the proper situation of which is of the greatest importance, forming, as they do, an essential feature of ex- pression in the human countenance. The superior maxillary bones, which com- prise what, in common language, is styled the upper jaw, do not generally display that ample development in the people of this country.
