lizard's neck (IK), or the lizard's loins (LM). 

 Now as all the units of these several regions

A B, c D, the neck and loins of the ostrich ; E F, 

 the human cervix, with cervical ribs ; G u, the 

 loins of a mammal ; i K, the neck of a lizard ; 

 L M, the loins of a saurian (crocodile) ; N o, a 

 part of the ophidian thoracic skeleton. 



of the same and of different species, evidently 

 illustrate the simple law of the archetypal 

 plus ens of the thoracic sterno-costo-vertebral 

 quantity, undergoing a graduated metamor- 

 phosis into less quantities of a neck or loins, 

 so I have equated in dotted outline, all those 

 parts which the minus quantities have ac- 

 tually lost ; and thus I have in idea given 

 creation to their whole or plus originals ; and 

 the reader will observe that by this very mode 

 of equation between the plus and minus seg- 

 ments of A 15, C I), E F, G H, IK, L M, I have 



equated them likewise with the plus series 

 N o, which represents part of the ophidian 

 thoracic skeletal axis. The fact likewise may 

 be noticed in this place, which will be more 

 fiilly considered hereafter, that in Jig. G H the 

 parts b, c, d, which are represented in dotted 

 outline as the quantity lost to the shortened 

 ribs , , are those very structures which in 

 the saurian venter opposite its lumbar spine 

 L M, appear as the ventral ribs (c, r), joining 

 a ventral sternum (d, d) ; and there appears 

 ventrad of the saurian cervix (i K) that series 

 of osseous pieces marked c, d, amongst which 

 I find the bones (e*r*), known as clavicles 

 and coracoids. Are these clavicles and cora- 

 coid bones which appear ventrad of the cer- 

 vical spine, in reality only as persistent parts 

 of the whole sterno-costo-vertebral arche- 

 types ?

A, the seventh cervical vertebra of the human neck ; 

 B, the seventh of a bird's neck ; c, the seventh of 

 a serpent's spinal axis; D, the seventh cervical 

 vertebra of the human neck, producing a, b, the 

 cervical ribs ; E F, o n, vertebral segments of the 

 ostrich, taken from the caudex E, neck F, loins G, 

 and thorax H. 



When I compare all those spinal regions of 

 several species of animals represented in
