    The development of the ribs being exhibited by one curve, that of the hyoid bone, lower jaw, &c. may be shewn by others. If the curve A B, represent the development of the spinal cord, A E may serve to shew that of the most elaborate por- tion of the hemispheres; and the intervening curves, the deve- lopment of intermediate parts of the cerebro-spinal axis.* All the nerves connected with the latter, may be illustrated in the same manner;—they seem, as it were, rude copies of each other, —differing only in direction and degree. Secondly, Let the point A be considered as the common ori- gin, in the fleshy portion of the lamina dorsalis and ventralis, of a series of osseous arcs, which, taking those of both sides, form an outer tube, including the upper and the under tube.
