MANGE. 201 



The mang-e has some permanent and fixed varieties; it has 

 also some anomalies. One of the most common forms under 

 which it appears is by a scabby eruption, which breaks out 

 on various parts of the body ; sometimes confined to the 

 back: in other cases extending to the arms, thighs, and joints. 

 These eruptions are first pustular ; but in some cases they are 

 simple cracks of the skin, exuding a serous discharge, which 

 concretes into scabs. 



Another form of the complaint is called the red mans:e, 

 from a redness of both skin and hair in the parts affected. 

 In this variety there is less pustular eruption, but nearly the 

 whole skin of the body, particularly in w^hite-haired dogs, is 

 in a state of active inflammation : it is also hot to the feel, 

 and itches intolerably. In the red mange, the hair itself be- 

 comes morbidly affected, and alters in its colour, particu- 

 larly about the extremities. It also falls off, and leaves the 

 body almost bare when the disease has continued long. The 

 strong coarse kind of hair, called wired, is more peculiarly 

 liable to suffer this discolouration. 



Another form of mange, but one much less frequent than 

 either of the former, appears to be a peculiar affection of the 

 sebaceous glands, by which they become internally ulcer- 

 ated, and have their sebaceous outlet preternaturally enlarged. 

 The affection seldom shews itself universally, but partially, 

 as over the face, around the joints, and in solitary patches 

 over the rest of the body. The affected parts are tumid, 

 shining, and look spongy ; from the little openings of which, 

 a moisture, between mucus and pus, issues. I have never 

 seen this affection but in the larger breeds of dogs ; and usu- 

 ally, I think, in pointers and setters. 



A fourth appearance that mange frequently assumes is call- 

 ed, by sportsmen, a su7:feit. It appears, in many cases, the 

 consequence of some active inflammatory state of the consti- 

 tution, generally of some local internal inflammation in par- 

 ticular. In these cases it puts on something of an acute form. 

 Thus bitches after pupping, and dogs newly recovered from 

 distemper, are often attacked with it. Other sources of fe-
