affected parts ; a certain spongy texture of a disagreeable, 

 scarlet or bluish color, and called "proud flesh," is formed, 

 which extends and grows over the opening of the sore. 



4th. Exudation. Properly, inflammation always pro- 

 duces a certain degree of exudation, but now we have to 

 refer to such exudations only as occur after an inflamma- 

 tion has subsided. Exudation consists of blood, water and 

 fibrous matter. Bloody exudations are of rare occurrence, 

 and are in most cases the consequence of a rupture of blood- 

 vessels, occasioned either by external force or by an exces- 

 sive swelling and overloading of such blood-vessels. Exu- 

 dations and effiisions of water, or of fluids which are very 

 similar to lymph, very often occur, either in the interior or 

 upon the surface of the membranes which cover the ab- 

 dominal cavities, or in the cellular tissues. In many cases 

 of inflammation of the chest, a large amount of water is 

 exudated through the inflamed diaphragm. In others, and 

 especially in nearly all violent inflammations, exudations 

 of fibrous matter, often of very large amounts, take place. 

 This often aflfects adjoining parts ; for instance, the lungs 

 may adhere to and grow together with the chest. In most 

 cases -exudations of water and of fibrous matter occur at 

 the same time. 



5th. Callosity. Whenever a part remains in a hardened, 

 enlarged and stifiened state after an inflammation of the 

 same has subsided, we call the issue of such inflammation 

 " callosity." Such a callosity is nearly always the conse- 

 quence of exudation of fibrous matter, remaining as a de- 

 posit in the previously inflamed parts. Such callosities are 

 often connected with dangerous consequences, although in 

 a great many cases only trifling or scarcely any conse- 

 quences whatever are perceptible. 



6th. Gangrene. This is the most fatal of all issues, pro- 

 ducing the decay of the diseased parts, or, if such a decayed
