The ascending rami are disproportionately broad, the condyles disproportionately high--the tip of the right coronoid process being 5.8 cm., the uppermost part of the condyle of the same side 6.7 cm. above the horizontal. The angles are very perceptibly inverted, so that while the diameter between the middle of the ascending rami measures 9.8 cm., the bigonial line is only 9.2 cm. The jaw is also asymmetrical, the upper part of the right ascending branch inclining somewhat towards the median line while that on the left inclines a little away from the same. The cause of the last-named condition is not perceptible, the base of the skull being quite symmetric and the lower dental arch normal. The usual internal reinforcement of the dental arch is but little developed. The teeth are of moderate size and only slightly worn. The dentition has been normal, there are no abnormalities or disease of the teeth and none of these have been lost in life. Measurements And Indices. Capacity 1380cc. cm.
