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 development of the superior maxillae, zygomae and nasalbones, with a normal lower jaw. A marked ridge extendsthe entire length of the vault at the suture. The distanceoutside of first molar is 2; outside second bicuspid, ; widthof vault between second bicuspid, 1; height of vault, .62,. Fig. 58. The chest walls are very contracted, the shoulders consid-erably stooped, and chest expansion very slight. Owingto the death of his parents it is impossible to state whetherthis is a direct inheritance or an arrest of development in theindividual. Case III, Fig 56.—A young man, twenty years of age, amarked neurotic; bookkeeper; is above the average in intel-lect; has a bright, piercing eye. The appearance of the faceand jaws are about the same as Fig. 55, with this exception,that the zygomse are a little more developed. Width out-side first permanent molars, 2; outside second bicuspid, ; THE HEAD, PACE, JAWS AND TEETH 237 between second bicuspid, ; height of vault, .59. Thereis a total collapse of the nasal openings, causing him to breathethrough the mouth since he was four years of age; the twosides of the left nostril approximate, v»^hile the turbinatedbones upon the right side, owing to hyp
