    optic nerve was much smaller than the left. 3. The motor oculi appeared to be absent on the right, normal on the left side. 4 and 5. The fourth and fifth nerves were normal. 6. The abducens was absent on the right, and small on the left side. 7. The facial and auditory nerves were very small on the right, normal on the left side. 8. The glossopharyngeal, pneumogastric, and spinal accessory nerves were absent on the right, normal on the left side. 9. The hypoglossal nerve was wanting on the right, normal on the left side. II. The Lower Jaw.—The line of the symphysis menti ossi¬ fied and vertical, internally marked by a distinct groove. Only the left genial tubercles well marked. Beneath the left incisor and canine teeth the margin of the jaw was curled outwards and upwards, producing a deep groove parallel to the margin. The mental foramen was deficient on the left side, extremely minute on the right (deformed) side, but transmitting a minute filament. The inferior dental foramen and nerve were normal, as were all the ridges and fossse on the left side. On the right side of the jaw the teeth behind the lateral incisor were crowded together, the canine being pushed forward, and the two temporary molars being con¬ tained in a stumpy alveolar process, which ended posteriorly in a rounded spine or tubercle. There was no lower border on the side of the jaw, but merely alveolar process. None of these teeth had erupted. The two central incisors and the right lateral incisor were the only teeth seen above the gum. The left lateral and the canines were seen above the bones, but were not through the gum. The central incisors were decayed at their cutting edges. On the left side the first temporary molar was seen underneath the perios¬ teum of the alveolar process, and an expansion of the bone showed the position of the second molar, while another expansion just beneath the anterior edge of the coronoid process seemed to indi¬ cate the position of the first permanent molar. n Measurements of the Lower Jaw.
