The cyclopædia of anatomy and physiology cyclopdiaofana03todd Year: 1847 826 character and entering into the formation of very numerous and diversified sets of organs, which have in reality no alliance with each other except that of mere juxta-position. One compartment in Man, exceeding in size all the rest put together, but in the lower Ver- tebrata forming but a very small part of the whole, is obviously merely a continuation of the vertebral canal lodging the most anterior ganglia of the cerebro-spinal axis, which it arches over and defends, at the same time affording passage to the nerves that emanate therefrom, being essentially itself composed of vertebrae, although, in consequence of the preponderating size of the brain over the spinal ganglia behind, considerable distortion is re- quired, a distortion which in human beings is necessarily carried to such an extent that the normal construction of this part of the skeleton is in man almost wholly indistinguishable. As the vertebral column forms the centre and sup- port of the trunk and limbs, so does the cranial portion of the skull sustain various additional apparatus, which may be enumerated as follows. 1. The auditory apparatus most frequently en- closed in a special bone, the petrous, and interca- lated among the proper bones of the cranium. 2. The temporal apparatus, which in man is confused into a single irregular mass that forms part of what the human osteologist calls the temporal bone, but which in the lower Ver- tebrata, such as the Keptilia, consists of several important pieces, which being withdrawn from the composition of the cranial box are employed for the articulation of the lower jaw, and more- over in the osseous Fishes sustain the bones of the gill-covers. (Nos. 12, 13, 23, 26, 27.) The following table, showing the numbers by which the corresponding bones appertaining to the cephalic portion of the skeleton are indicated in all
