202 MANGE. 



bril© imtation may also produce it: thus when a dog travels 

 during' a ^reat part of a very hot day, and becomes after- 

 wards exposed to cold, a surfeit is sometimes the consequence. 

 Likewise, after other inflammatory attacks, an eruption sud- 

 denly appears, accompanied with g-reat heat and redness, it 

 is usuallv seen in the form of blotches, and it is but seldom 

 that it extends universally over the body. In some cases 

 there is little appearance of raised scab, but large rough 

 patches shew themselves, from which the hair falls, and leaves 

 the skin bare and even, except the elevation occasioned by a 

 branny scaly eruption, which itches with more or less vio- 

 lence. Some sportsmen think a surfeit occasioned by giv- 

 ing the dog his victuals when too hot. Salt provisions, it is 

 certain, will occasion it ; and long-continued feeding on oat 

 or barleymeal will also bring it on in some instances. 

 " The Anomalies of mange are several. Canker within the 

 ear, and that without also, are affections whose origins are 

 mano-y. Inflamed scrotum and ulcerated claws are of this 

 class, as well as ulcerated eyelids also. The general treat- 

 ment of all these must be the same ; the immediate applica- 

 tions proper, are detailed under the several heads. 



An acute mange also now and then appears. In these 

 cases a violent febrile affection attacks the animal ; he pants, 

 and is very restless. Some part of the body (usually the 

 head) soon begins to swell, v,'hich, the second or third day, 

 gives place to ulceration of the nose, eyelids, lips, and ears. 

 This ulceration proves superficial, but extensive; and con- 

 tinues a longer or a shorter period, as the treatment is more 

 or less judicious. Bleeding, aperients, and febrifuges, form 

 the constitutional remedies. The topical ones are tepid fo- 

 mentations the first two days ; and, when the tumefaction 

 has given place to ulceration, the apphcation of a cooling 

 unguent of superacetate or sugar of lead, with spermaceti 

 ointment, will be proper. What remains of the affection, in 

 a week or ten days' time, may be treated as common mange. 



Mange is universally considered as troublesome and loath- 

 some, but it is not generally considered as otherwise hurtfuh
