 it to nnother under similar circumstances. It is pro* 

 bable, therefore, that some peculiar state exists in the 

 constitution sonieiimes that renders it less easily taken 

 than at others, and in some dogs than in others. It 

 will be found that hereditary and constitutional 

 mange is not so contagious as that which is caught 

 from another animal. The disease has verv consider- 

 able varieties; the most connnon kind is a scabby 

 eruption along the back from the neck to the tail : in 

 large dogs it is often worst across the shoulders ; in 

 lesser dogs it is worse towards the tail. It comes also 

 under the neck and behind the arms. Another 

 variety is, when there are no scabs, but an universal 

 redness aud intolerable itching of the skin. Some- 

 times this has a pecuhar tendency to discolour the 

 hair, particularly in white wire-haired dogs, and in 

 setters ; it is then called red mange, and this kind is 

 very dithcult of cure. The mange often fixes itself 

 to one part : when in the ears, it produces canker ; 

 w hen on the outside of the ear, it is the outer canker. 



It often fixes itself also in the toes, and makes a 

 raw red-lookin^g sore between the claws, but which 

 is seldom considered as mange, but will be found so. 

 See ClA"\ys. In some instances it fixes itself in the 

 eyes, and such dogs have matter always running from 

 the eyes, as though they had distemper ; in others it 

 is in the eyelids alone, which it makes bare. 



Mange may be equally produced by too full or too 

 poor living ; consequently the cause must be attended 

 to, to effect the removal. In full plethoric dogs bleed- 

 ino' is very useful, and in dogs who have been nearly 

 starved it will be necessary to improve the condition.
