OF THE CELLULAR TISSUE. 125 



seton, &c. frequently reduces the inflammations of the other 

 organs. 



152. The cellular tissue is subject to various morbid 

 changes. When broken into and exposed, it inflames, becomes 

 covered with fleshy buds, suppurates, and at last covers it 

 \vith a cicatrix or new skin which will be described hereafter. 

 (Chap, iii.) 



When it is cut and its divided surfaces are again brought 

 into contact, they, at first, agglutinate by means of a liquid 

 poured out from the divided surfaces when the bleeding and 

 pain have ceased. A little later, and this organizable substance 

 becomes a highly vascular tissue: then it is no longer possi- 

 ble to separate the lips of the wound without renewing the 

 pain, and reproducing the flow of blood. This new tissue re- 

 mains for a long time, more compact, firm and vascular than 

 the cellular tissue it unites and with which it is at last con- 

 founded. 



It is by a similar process that every union of divided parts 

 .takes place, with modifications relative to each tissue, which 

 will be examined in their proper place. 



It is, also, in this way that adhesions are formed between 

 contiguous surfaces of the serous arid tegumentary membranes, 

 adhesions that will be described when we come to treat of 

 membranes. (Chap, ii, iii.) 



The cellular tissue is susceptible of an extroardinary growth : 

 when exposed, it sometimes shoots out in a kind of vegetation 

 or vascular exuberances. The reproduction of this tissue is in 

 general so much the easier, as the quantity that remains in 

 the spot from which it was taken is great: it seems that this 

 reproduction depends, in a great measure, upon the extension 

 of the pre-existing cellular tissue. 



The inflammation of the cellular tissue, or phlegmon, is 

 characterized by various changes in this tissue. The first of 

 these changes, is a highly marked increase of vascularity. 

 The inflamed cellular tissue becomes, besides, sensible and 

 painful; it entirely loses its permeability; liquids can no longer 

 pass through it; its consistence augments and its tenacity di- 

 .m.inishes; pressure tears and breaks, instead of elongating it,
