The etiology of osseous deformities of the head, face, jaws and teeth . he alveolar pro-cess, although small for the body, has normal dental outside first permanent molar, 2; outside secondbicuspid, ; width of vault, ; height of vault . molar not present, and teeth small, hence the reasonfor no deformity. Case II, Fig. 55.—Is that of a young man eighteen yearsof age. His mother died of epilepsy when he was two yearsold. Father died of locomotor ataxia about six years ago. THE HEAD, FACE, JAWS AND TEETH 235 He, therefore, has inherited a marked neurotic lower jaw seems to be quite prognathous, while the face,from the upper border of the lower teeth to the superciliaryridge, is markedly concave. The superior maxillary bones,as well as the zygomse, are arrested in their eyes have a sleepy look and are quite deeply set in thehead; forehead narrow and quite prominent. This seems tobe a case of atavism. There is a total collapse of the wallsof the nose, difficulty in breathing, hypertrophy of the tur-.

In this case, we cannot say that the lowerjaw is excessively developed, because the teeth, which arenot large, just fill the space, while the incisors do not pro-trude, and the third molars are in place. The upper jaw,however, is greatly arrested in its development. The thirdmolars are not present. They could not erupt if they werethere for want of space. (My experience has been that thethird molar is nearly always missing in neurotics and degen-erates.) The left first bicuspid has been extracted, thusallowing spaces to occur between the incisors. In order that 236 ETIOLOGY OF OSSEOUS DEFORMITIES OF the teeth may all come into position, the anterior alveolarprocess has been pushed forward .60 of an inch. If thebones of the face had developed, the lower jaw would haveappeared to a better advantage. This case shows an arrestof developmen
