338 BIOLOGY. 



plant resides accordingly in this, that the vegetable tissue 

 consists of actual vesicles, which form everywhere closely 

 compressed masses ; the animal cellular tissue on the 

 contrary of granules, which inclose a hollow space. The 

 animal body is a hollow globe of vesicles, the vegetable 

 body one full of vesicles. (Ed. 1st, 1810, 1870.) 



1867. Every animal cyst is necessarily composed of 

 the element of the vesicles, and is then for the first time 

 an organ. The vegetable bladders are, however, single 

 vesicles, and as such are already an organ. In the plant 

 therefore the cellular tissue is upon the lowest stage, 

 being only an aggregate devoid of secondary form ; in 

 the animal along with its aggregation a secondary form 

 has been imparted. In this the higher character of the 

 animal is at once demonstrated. 



1868. The above is certainly a distinction between the 

 two organisms, but it is not the essential one ; for with 

 it, what is animal has been by no means expressed ; this 

 being first imparted in the three cosmic elemental forms, 

 which manifest themselves through sensation and motion, 

 and then admit of being recognized as an animal. The 

 corolla is also a cyst, but without being an animal ; be- 

 cause, to this animal-like tegumentary formation, the pro- 

 per animal elements are still wanting. 



1869. Now as the tegument is none other than the 

 form, under which the cellular tissue exists in the ani- 

 mal, we must regard it as an elemental form, which has 

 stepped into the place of the cellular. The tegumentary 

 form constitutes the fourth form, and is none other than 

 the primo-vesicular form elevated to a higher rank, by 

 being composed of cell-granules, which have been for- 

 merly nerve-granules. 



1870. The animal body must consist of nerve, muscle, 

 bone, and tegument, and of no other fundamental form ; 

 in other words, of point, line, globe, and cyst. 



u. Anatomical Systems. 



1871. All anatomical systems are developments and 

 separations of the four tissues, which are prolonged
