The etiology of osseous deformities of the head, face, jaws and teeth . tly above the maximum given by most type is as marked in the direction of a brachycephalicindex as is Fig, 32 in the direction of a low, or dolichocepha-lous index. Fig. 43 shows the inferior surface of the skull under con-sideration, A glance suffices to show its remarkable asym-metrv. The foramen magnum is almost entirely to the leftof the median line. A line drawn through the center of theforamen traverses the median line of this surface at an angleof about forty-five degrees. The center of the anterior bor-der of the foramen is situated at mm, from the left and58 mm. from the right mastoid. The center of the posterior THE HEAD, FACE, AND TEETH 151 border of the foramen is 64 mm. and 61 mm. from the left andright mastoids, respectively.
