274 MANGE. 



tion seldom shews itself universally, but partially, as over the face, 

 around the joints, and in solitary patches over the rest of the body. 

 The diseased parts are tumid, shining, and look spongy ; from 

 the little openings of which a moisture, between mucus and pus, 

 issues. I have not observed this affection but in the larger breeds 

 of dogs ; and usually, I think, in pointers and setters. I have seen 

 it almost entirely confined to the eyelids, as noticed in Diseases of 

 the Eyes. 



A cuticular eruptiofiy called surfeit^ is a fourth appearance that 

 mange frequently assumes. It seems, in many cases, the conse- 

 quence of some active inflammatory state of the constitution, fre- 

 quently of some great local internal inflammation ; in which cases 

 it puts on something of an acute form. It sometimes breaks out 

 suddenly in bitches after pupping, and in dogs newly recovered from 

 distemper ; in fact, any great vascular excitement may produce it : 

 thus, when a dog travels during a great part of a very hot day, and 

 becomes afterwards exposed to cold, a surfeit is oftentimes the 

 consequence. It is usually seen in the form of partial blotches, it 

 being seldom that it extends universally over the body. In some 

 cases there is little appearance of elevated scab ; but large patches 

 shew themselves, from which the hair has fallen, and left the skin 

 bare and rough from the branny scaly eruption, which itches with 

 more or less violence. Some sportsmen allege that a surfeit is 

 sometimes occasioned by giving food in a hot state. Salt pro- 

 visions have certainly brought it on ; and long-continued feeding 

 on oat or barley-meal has done the same. 



Acute mange. — Besides that variety just noticed, there is yet a 

 more directly acute form of the complaint, which puts on an ap- 

 pearance not unlike erysipelas in some instances ; in others it is a 

 pure erythema, or red efflorescence ; but more frequently it is ac- 

 companied with some ulceration. It commences by a direct febrile 

 attack, with panting, heat, and restlessness ; next some part of the 

 body (usually the head) begins to swell, which, the second or third 

 day, gives place to ulceration of the nose, eyelids, lips, ears, neck, 

 &c. This ulceration proves superficial, but extensive ; and con-
