of the nails, where there are considerable redness and swelling; 

 and so much tenderness as to make the dog quite lame. In bad 

 cases when the constitution is impaired by defective kennel 

 arrangements, the sores become very foul, and are then very 

 difficult to heal. In order to remove this state of things,' the 

 general health must first be attended to, using the same means 

 as in " blotch " if the cause is the same, and touching the sores 

 themselves with blue-stone, which should be well rubbed into the 

 roots of the nails, first scraping it to a fine point. When the 

 health is much impaired and the sores are in the foul state 

 described above, give from five to eight drops of liquor arseniccdis 

 with each meal, which for this condition should be of good nour- 

 ishing food. This remedy must be continued for weeks, or even 

 months in some obstinate cases. Here, after applying the blue- 

 stone, it is often of service to rub in a very little tar-ointment, 

 and then dust all over with powdered brimstone, dipping the foot 

 into a box of it, being the best mode of applying it. 



Foul mange (resembling the psoriasis of. man in its nature) is 

 a most unmanageable disease, inasmuch as it has become quite 

 constitutional before it can be so designated, and because, being a 

 disease of the blood, it requires a complete change in the com- 

 position of this fluid before it can be eradicated. It is doubtful 

 whether mange is contagious, but' that it is hereditary I have no 

 doubt whatever, the proofs within my own knowledge being 

 amply sufficient to convince me of the fact. Thus I have seen a 

 bitch apparently cured of it, and with a perfectly healthy skin, 

 produce a litter of whelps all of which broke out with mange at 

 four or five months old, though scattered in various parts of the 

 country at their walks ; the bitch afterwards showing the im- 

 purity of her blood by again and again becoming the subject of 

 mange. I should therefore never breed from either a dog or
