1863. The idea of the integument is the wall of a cyst. There is no tegument apart from the meaning of circumscription, inclusion, and limitation. There is no flat integument, or one that could be designed after the idea of the plane. Every tegument is periphery, just as there is nowhere a surface in the universe, which could have been produced according to the level or plane. 1864. All terrestrial processes, as digestion, respiration, and nutrition, are consequently tegumentary processes. All these organs must be tegumentary organs. Intestine, vessel, lung, in a word all viscera are naught but tegument. 1865. The vegetable tissue becomes in the animal, tegumentary tissue. The tegumentary formation is the vegetable in an animal--the parenchyma, the _Visceral_. 1866. The lowest distinction between animal and 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; because, to this animal-like tegumentary formation, the proper animal elements are still wanting. 1869. Now as the tegument is none other than the form, under which the cellular tissue exists in the animal, 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 formerly 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. II. _Anatomical Systems._ 1871. All anatomical systems are developments and separations of the four tissues, which are prolonged as sheaths through the whole body, like as in the plant are the bark, liber and wood.
