. Elements of pathological anatomy. Anatomy. CHAP. II.] ORGANIZATION. 229 stance penetrates into their interior, it becomes gradually more dense, short, and delicate, until it finally escapes obser- vation. Under the skin, the cellular tissue is spread out in the form of a lamella, which can be traced as a continuous whole from one region of the body to the other, and which constitutes what, in surgical language, is denominated a fascia. It may also be stated here that this substance receives differ- ent names, according to the organ with which it is associated, as subcutaneous, retro-peritonseal, submucous, inter-muscular, and subserous. The peculiarities which it exhibits in these localities will be pointed out in their proper places. The cellular texture is highly extensible and elastic, and is thus well qualified to discharge the various functions that have been assigned to it in the animal economy. Another property possessed by it is the hygrometric, by virtue of which it expands and regains its primitive softness and pliancy, when immersed in water after having been dried. It is composed principally of albumen, in union with a little gelatine, the quantity of which is always less in the old than in the young. It resists putrifaction for a long period, and is not easily broken down by boiling. Exposed to destructive analysis, it yields oxygen, hydrogen, carbon, and azote. The cellular substance is every where lubricated by a thin watery fluid, the presence of which is essential to the due exercise of its healthy functions. It is of an albuminous nature, and iden- tical with the serum of the blood, whence it is derived. Examined in reference to its structure, (Fig. 7,) this tissue is found to be composed of whitish fila- ments, homo- geneous, soft, and transpar- ent, which in- tersect each other in all di- rections, form- ing thereby an infinity of cells which freely communicate together over the entire body.
