ZOOLOGY. 503 



3106. Now, the vegetative body divides into three 

 principal systems, into the Intestinal, Vascular, and Re- 

 spiratory system, with their functions, or the digestive, 

 nutritive, and respiratory processes. There are therefore 

 Intestinal, Vascular, and Respiratory animals. 



Circle I. Intestinal Animals. 



3107. The intestinal system is the first form of body, 

 or that from which the other systems have not yet sepa- 

 rated. The body of these animals consists therefore of 

 the homogeneous primary mass the animal protoplasma, 

 mucus or slime Mucus-animals. 



Now, the protoplasma is a hollow globule. The intes- 

 tinal system is therefore nothing else than the original cystic 

 form. Thus, there are Cystic animals like the Infusoria. 



Again, cysts can increase in no other way, than by 

 dividing into their like, or engendering cysts within 

 themselves. The first kind of increase or multiplication 

 of species is thus fissiparous, or produced by division. 



The newly-engendered cysts are to be compared with 

 the vitellus, and when they have attained perfection, to 

 the ovum. They are therefore Oozoa or Ovum-animals. 



In these animals consequently there are no separated 

 sexual parts, namely, in addition to the vitelli, neither 

 testes nor renal organs, or at least only obscure indi- 

 cations of them. In these Cystic animals the lowest feel- 

 ing only, that of the sex or general sensation, can occur. 



The Oozoa or Cystic animals, when compared with the 

 plants, are the first flower that has been set free, or in 

 other words, a flower which no longer stands polarwise upon 

 a stem, because it is not developed in the differencing air, 

 but in the indifferent water. It may be said ; that nature, 

 having brought matters as far as the development of the 

 sexual parts, then quits or passes out of the vegetable world; 

 while these parts, or even the entire plant, requiring now 

 no longer the stem and root, become a root themselves, 

 and in behalf of this enter the water. 



Animals, which have the form of flowers, are round 

 or radiiform. There are Eadiata or Radiated animals.
