598 Dr. WALTER ADAM on the 
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 vertebre, are,

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, 91139, 254i 
While the breadths at the roots of the rostral oblique processes 
of the | same B: boii tue 3rd and 7th cervical vertebrz) are,

Min the celvidil vertebrae of bes 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 vertebrz attain their 
full development. 
In the cervical vertebrae of the animal examined, a curtail- 
ment of the caudal oblique oe of the 6th on the right side,
