curidl preparation applied by tlie keeper for the cure 

 of mange. Calomel is very irre!:^iri-cir in its action on 

 dogs : I have seen ten grains fail of opening the 

 bowels of even a small one, while I have been called 

 in to see a pointer fatally poisoiied by the same dose. 

 Even wlien intesided merely as a j)urgative, it will fre- 

 c|uently hardly irritate the bowels, but very ftdiy irri- 

 tate the mouth. Sulphur is the article most generally 

 given to dogs as an alterative in domestic )>ractice ; 

 but it 16, I believe, almost wl;oily inert and useless, 

 ■^rhere is nothing in w'iich persons ' keeping dogs are 

 more deceived than in their or>inions of the etiicacy of 

 sulphur as an alterative. It is a very conunon practice to 

 put a roll of brimstone into the nans from whence doijs 

 di iiik their water ; and from the virtues which tliis 

 is to iju'.iart to the water, they expect to keep their 

 dogs in health: but so conipletelv insoluble in water 

 is brimstone in this state, that a roll of it would not 

 lose ten grains of its weight in ten years, though con- 

 stantly kept in water ; or would it l.-ecome in the least 

 altered in its quality. Sulphur in general passes 

 throuah tlie bowels as it was taken in without beins; 

 in the least altered, or without being taken into the 

 system. In some cases it proves slightly purgative ; 

 but in tills resj)ect it is very uncertain. 



But the best alteratives for dogs are those which 

 are judiciously compounded of several articles that do 

 not chemically interfere with each other. The com- 

 pound I in general admiiiister and recommend (page 

 i2*2) I can with truth aftlrm to be a most excellent al- 

 terative in mange, and all eruptive complahits. It 

 greatly assists the use of external applications in de- 

 tided mange; in slight cases is equal to the cure
