The etiology of osseous deformities of the head, face, jaws and teeth . e upon the opposite sideof the vomer to correspond to the line of projection.

The lengthof this projection would also preclude such an idea. These 270 ETIOLOGY OF OSSEOUS DEFORMITIES OF projections vary from a mere ridge up to a projection .36 ofan inch in width. It would seem that nature, being unableto develop the bone sufficiently to carry it far enough, builtout a projection in order to complete its design. These projections were first mentioned by Langenbeck,who gave to them the name of exostoses. They were after-wards described by Theile, Harrison Allen and John Mac-kenzie. These projections, says Bosworth, are alwaysfound along the sutural lines of the septum, and consists in amore or less well-developed angular prominence or ridge,which, projecting into the nasal passage, acts to obstructnormal Fig. 82. This has not been my experience, as I have always foundthem situated upon the convex surface, and the greatest pro-jection being at the weakest point of the septum. As thegreatest deformity may be located at any point between theanterior and posterior edges of the bone, we are liable to findthe greatest point of projection on any part ot the septum,but they are always situated midway between the turbinatedbones. This projection I believe to be due to irritation, theresult of inhalation and exhalation. From the observation made it would seem that the deflec-tion of the vomer was due to a wise provision of nature.
