parts covered by the skin. Nevertheless an increase of 

 redness always takes place whenever an inflammation oc- 

 curs, which may be observed at the dissecting of the car- 

 cass, or whenever an internal part is exposed either by 

 accident or design. The redness of the inflamed womb or 

 intestines is generally not perceptible on account of the 

 situation of those parts, but may become visible whenever, 

 from the injury of the abdomen or at difiicult birth, the 

 intestines or the womb are turned outward and become in- 

 flamed in the body. There are, however, some parts upon 

 which in their inflamed state an increased redness is always 

 perceptible without difiieulty (as, for instance, upon the 

 mucous membranes, the nose and the vagina), as also upon 

 the connecting membranes of the eyes, the udder, and 

 where the body is affected with pox. 



II. Increased warmth. An inflamed part contains a 

 greater degree of warmth than in its healthy state, and 

 such an increase is easily perceptible upon nearly all ex- 

 posed spots, or such spots as can be reached by the hand. 

 In internal inflammation, however, it is always very diffi- 

 cult, if not impossible, to detect such an increased degree 

 of warmth. We have therefore to depend upon such in- 

 dications as are either popularly known or are of a singular 

 nature, or upon the increased temperature of the skin, the 

 nose, the interior of the mouth, the breath, the eye, etc. 

 The cause of the increase of warmth in inflamed parts ie 

 the increased accumulation and circulation of the blood, 

 and the increased activity of the affected parts. 



III. Sivellinff. The inflamed part almost always appears 

 to be more or less enlarged or swollen, and becomes strained 

 and hardened in a measure, according to the constitution 

 of such inflamed parts. This swelling is caused by the in- 

 creased pressure of the blood, eff'usion of the blood, lym- 

 phatic or fibrous matter, and as a consequence of the
