SKELETON continued. 



the variable proportionals of sterno- 

 costo-vertebral archetypes, iv. 638. 

 XXXII. the h void apparatus occurs opposite to the 

 cervical spinal region, where we know 

 costal quantity to be lost; the hyoid ap- 

 paratus refers to the cervical vertebra, 

 and consists of their ribs metamorphosed, 

 iv. 640. 



XXXIII. the ventral apparatus occurs opposite to the 



lumbar spinal region, where we under- 

 stand that costal quantity is lost; the 

 ventral apparatus refers to the lumbar 

 vertebrae, and consists of their ribs meta- 

 morphosed, iv. 643. 



XXXIV. clavicles, coracoid bones, and ribs are iden- 



tical parts of the costo-vertebral whole 

 quantities or archetypes, iv. (U4. 

 XXXV. marsupial bones, pubic and ischiadic bones 

 and ribs, are identical parts of the costo- 

 vertebral whole quantities or archetypes, 

 iv. 648. 



XXXVI. chevron bones and ribs are identical parts 

 of the costo-vertebral whole quantities or 

 archetypes, iv. 650. 



XXXVII. the sternal median line ranges from the 

 maxilla to the pubic bones of the abstract 

 archetypal skeletal fabric, iv. 6.51. 



XXXVIII. every fossil skeletal species of extinct 

 animals, as well as every recent existing 

 species of skeleton, is a form created of 

 the archetypal skeleton, iv. 655. 



XXXIX. the cranio-facia! apparatus consists, like the 

 thoracic apparatus, of variable propor- 

 tionals of the stern o-costo-vertebral quan- 

 tities, iv. 655. 



XL. the scapulary or fore-limbs of all the verte- 

 brated animals are homologous to one 

 another; the variety among these or- 

 gans occurs by a metamorphosis or omis- 

 sion of elementary quantity, iv. 661. 

 XLI. the scapulary and pelvic members are ho- 

 mologous, iv. 664. 



XLI I. the sterno-costo-verfebral quantity is a pro- 

 portional of the dorso- ventral quantity, 

 iv. 667. 



XLIII. the scapulary and pelvic pairs of limbs are 

 proportional quantities metamorphosed 

 from the dorso-ventral archetypes, iv. 

 669. 



XLIV. the cranio-facial apparatus of segments are 

 proportionals of the dorso-ventral arche- 

 types, iv. 673. 



XLV. the cranio-facial apparatus is the origin of 

 the dorso-ventral archetypal series, and 

 the caudal apparatus is its termination, 

 iv. 673. 



XLVI. the uniform archetypal series undergoes a 

 graduated metamorphosis of its quanti- 

 ties for the production of all varieties of 

 skeletal species, iv. 674.
