to undergo such a metamorphosis, since they first of all 

 resemble an Infusory animal, next change as pupae into 

 Molluscs, and are then manifested for the first time as 

 Worms. 



3299. The Dermatozoa or Sensitive animals range in 

 the following manner, according to the anatomical systems : 



A. INTESTINAL B. VASCULAR C. RESPIRATORY 



ANIMALS, ANIMALS. ANIMALS. 



1. Gastric animals. 4. Venous animals. 7. Reticular animals. 



Infusoria Mussels. Worms. 



2. Intestinal animals. 5. Arterial animals. 8. Branchial animals. 



Polyps. Snails. Crustacea. 



3. Absorbent animals. 6. Cardiac animals. 9 Tracheal animals. 



Acalephae. Kracken. Insects. 



3300. According to the developments of the feeling- 

 sense they stand thus : 



A OVUM-ANIMALS. B. SEXUAL ANIMALS. C. CUTANEOUS ANIMALS. 



1. Vitelline animals. 4. Ovarial animals. 7 '. Papillary animals. 



Infusoria. Mussels. Worms. 



2. Albuminose animals. 5. Or chitic animals. 8. Pedal animals. 



Polyps. Snails. Crustacea. 



3. Involucral animals. 6. Renal animals. 9. Alary animals. 



Acalephae. Kracken. Ehes. 



3301. From these tables the number and kind of 

 relationships or affinities is readily deduced. There is a 

 Relationship of Proximity, as that between Infusoria, 

 Polyps, and Acalephse. 



A Relationship of Repetition, as of Infusoria, Mussels, 

 Worms. There is also a Relationship of Series, which 

 takes its rise from the parallelism of the classes. The 

 two last relationships have been confounded together 

 under the term analogy, which is applicable only to the 

 last one of all. 



Second Province Sarcozoa, Cephalozoa. 



FOURTH CIRCLE SARCOSE ANIMALS. 



3302. The system of motion and sensation, which 

 broke forth so forcibly in the tegument, now passes over 

 into other forms, into the globular form of bone, the 

 fibrous form of flesh or muscle, and the point-form of 

 the nerves.
