 Adipose Substance, and in the Dermoid Covering.

CHAPTER I. 



OF THE CELLULAR SUBSTANCE. 



THE Cellular Substance (Textus Cellulosus, Mucosus) is an 

 elementary tissue, and is more generally diffused than any other 

 of the body, for it seems to be quite as indispensable to the lat- 

 ter as the corpus mucosum is to vegetables. It is found abun- 

 dantly beneath the skin; between muscles; in the interstices of 

 muscles and of other parts ; connecting membranes to one ano-

 Indispensable as it is to the texture of all other parts, we find 

 it, as may be expected, preceding them in the development of 

 the foetus; at which period it is in the condition of a fluid slight-
