PROP. XV. The seven cervical verlebrce are projwrlionak degraded from seven sterno- costo-vertcbraf whole quantities. — The same elemental quantity which is proper to a lumbar vertebra is to be found in a cervical vertebra. In both (\\defigs. 445. and 447.) we distinguish the centrum (5), the neural arch (2), the spinous (1), and transverse pro- cesses (3), and the costal rudiments (4). In both we find that the difference which they manifest on comparison with the costo-ver- tebral thoracic archetypes is simply a differ- ence in costal quantity ; and hence the same reasons which have been here advanced for regarding the lumbar segments as propor- tionals of sterno-costo-vertebral circles, may be also applied as proof of the truth of the interpretation that cervical vertebrae (such as fig. 454.), are also proportionals of the like Fig. 454. that the presential proportional condition of lumbar vertebras, consisting of the elements I, 2, 3, 4, 5, fig. 452.), manifests no other variety or species to the archetypal quantity 1, 2, 3, 4, 5, 6, 7, elsewhere persisting, than a simple quantitative variety. PROP. XIV. The sacro-cocci/geal series of vertebrce are proportionals degraded from sfer~ nal costo-vertebral circles.—That which is true of lumbar vertebra?, compared with thoracic segments, must be true of sacral vertebra; com- pared with the same. For as it seems that lumbar vertebrae are the proportionals of ster- nal costo-vertebral circles, so must sacral ver- tebrae, which are developed of elements iden- tica
