be very carefully guarded against, but, when any danger of this 

 kind has occurred, a dose of castor oil should be immediately 

 given ; after which, astringents, with a small proportion of washed 

 sulphur in them, will prove useful. — In the use of the unguents, 

 it is necessary to remark, that they are too apt to be smeared over 

 the hair without being applied at all to the skin itself. It re- 

 quires at least two hours to dress a dog thoroughly. The hair 

 should be parted almost hair by hair, and a small quantity of oint- 

 ment should be rubbed actually on the skin, between the parted 

 hairs, by means of the end of the finger. After every part is d(Jne, 

 the hair may be smoothed down, and the dog will appear, when 

 the operation has been neatly managed, nearly as clean as though 

 nothing had been applied. After three or four dressings in this 

 way he may be washed with soft soap and water, and the ointment 

 may be again rubbed in, and again washed off every fourth day, 

 until the cure is complete. In old and bad cases of mange it will 

 be frequently requisite to continue the treatment a very consider- 

 able time, to ensure a perfect removal of the complaint. I once 

 occasioned a very favourite setter, who had had virulent mange five 

 years, to be dressed every day, or every other day, for the extra- 

 ordinary period of twelve months, before I could completely con- 

 quer the disease : but this determined perseverance effected a per- 

 manent cure.

From confinement and luxurious living dogs become subjected 

 to various complaints, that evidently arise from the formation of 

 too great a quantity of blood and other juices ; which, not being 

 spent in support of the body, find themselves other outlets. 

 Canker in the ear is evidently produced by this disposition in the 

 constitution to throw oflF the superfluity accumulated within. In 

 these cases, the dog is first observed to scratch his ear frequently ; 

 on looking within which a dark red granular appearance is seen, 

 from dried extravasated blood. If the complaint is not stopped in
