which removes on more liberal feeding, and leaves 

 only fome flight fymptoms of common mange. There 

 is a variety of it, confifting of fpongy ulcers, from 

 the little pores of which fpongy furface, ferum, or the 

 watery parts of the blood, in the form of a yellow 

 thin fluid, confl;antly iffues in fmall drops :— this 

 variety is nearly incurable. 



Red mange is lefs eafy of cure than the rank 

 fcabby mange; it is often, likewife, conftitutional, 

 particularly in coarfe wiry-haired dogs : that is, 

 every fpring and fall it makes its appearance in fome, 

 and in others it is conflant ; for, as foon as the treat- 

 ment ceafes, it appears again. The progeny of 

 thefe dogs poffefs an hereditary mange ; and I would, 

 therefore, never recommend breeding from either 

 dogs or bitches under this difeafe. 



The rank fcabby mange is not difficult to cure ; but 

 its recurrence in fome dogs is certain, without a very 

 early repetition of the fame means with thofe before 

 adverted to. 



Mange may be generated, or it may be caught. It 

 is generated by the oppoflte extremes of too full feed- 

 ing, and too fparing a diet; that is, dogs may be 

 crammed into it, or llarved into it. Grofs food, as 

 horfe flefli, greaves, &c., will produce it, particularly 

 if the exercife is not proportioned to the food. Filth 

 is a very great caufe of it; for which reafon the 

 dogs of the poor commonly have it more or lefs.
