BLOTCH WARTS. 143 



but, on the contrary, to avoid this effect, and to cause the absorp- 

 tion of the arsenic into the blood, where it exerts its peculiar 

 power. What this is I do not at all understand, but the effect is 

 undoubted, and, as practice is better than theory, our ignorance of 

 the modus operandi is not very much to be deplored. 



BLOTCH is an eruption depending entirely upon the excessive 

 fullness and impurity of the blood, owing to want of exercise, and 

 high feeding. It generally attacks the greyhound either when he 

 is rested after severe work without altering his food, or when too 

 highly fed throughout the summer season. It comes on by a dis- 

 charge of thick serum among the hair, and is first detected by the 

 appearance as if some gum or starch had been dropped upon the 

 coat, and had matted the hair together. In a few days this falls 

 or is scratched off, and the skin shows itself red and deprived of 

 its cuticle, and continuing to discharge the same serum, which is, 

 however, constantly licked off by the dog's tongue. No external 

 remedies are here required, and the treatment should be by a dose 

 or two of calomel and jalap, or the alterative balls daily, with an 

 ounce of Epsom salts twice or thrice a week. The food should be 

 considerably reduced, and some green vegetables or turnips should 

 be mixed with it occasionally; the eruption seldom lasts more 

 than ten days. 



WARTS do not often occasion much inconvenience in the dog; 

 but if they do, they may either be removed by the knife, or by 

 rubbing in a little corrosive sublimate in powder, then wetting the 

 wart, and after a few minutes washing all off. This produces the 

 death of the wart, and it drops off in a few days.
