    its articulation with the occipital condyles, affords support to the lower jaw;—whence that graceful carriage of the head, so frequent a theme of the fervid eulogy of the Arabian poets. The sternal length of the 2nd vertebra of the neck is three times that of the atlas, and half the coronal length of the head. In this bone, the dimensions of length, the distance between its arteries and the breadth of its articulation with the 3rd cer- vical vertebra, are even numbers of proportional parts. The other dimensions are odd numbers of these parts. The succeeding bones of the neck diminish in length, while their dimensions of breadth and thickness increase. The decrements of length are irregular. Of the breadths, those of the rostral balls of articulation in- crease uniformly. The extremes, namely, the rostral globular articulations of the 3rd and of the 7th cervical vertebrae, are, :: 2:3. The other augments of breadth are irregular. But in the ex- tremes, the rostral ends of the plates that shield the gullet and trachea, are, :: 3:4. While the breadths at the roots of the rostral oblique processes of the same bones (the 3rd and 7th cervical vertebrae) are, :: 1:2. In the cervical vertebrae of the Camel, a depressed rudiment of a process appears on the dorsal ridge of the 5th vertebra. The 6th and 7th have complete spinous processes. A scabrous elevation on the lateral surfaces of the sternal plates that shield the gullet and trachea, marks the incipient transverse processes that in the lumbar vertebrae attain their full development. In the cervical vertebrae of the animal examined, a curtail- ment of the caudal oblique process of the 6th on the right side, and
