requires the aid of mercurial alteratives. Indeed, tl)c> assist 

 in every variety of it, but this one can hardly be cured with- 

 out. The following formula is a g-ood one: — 



Black sulphuret of quicksilver {Mthiops \ , 



mineral) J 



Supertartrate of potash {cream of tartar) I ounce 



Nitrated potash {nitre) 2 drams. 



Divide into sixteen, twenty, or twenty-four doses, according- 

 to the size of the dog-, and g-ive one every morning- or even-

Conserve of roses 1 ounce 



Flour of sulphur half an ounce. 



Divide into eig-ht, twelve, or fifteen balls, according- to the 

 size of the dog", and give one every day. 

 Or the following- : — 



Oxymuriate of quicksilver 3 grains 



Spring water 3 ounces. 



Dissolve, and make twelve or fifteen doses of it, according- to 

 size, and give one every night and morning. 



With regard to external applications, they should, particu- 

 larly when liquid, be used every day. The mercurial ones re- 

 quire some caution, both to prevent the dog from licking them, 

 and also to watch that salivation may not be occasioned by their 

 use. When mercurial preparations are licked by dogs, they 

 are apt to occasion violent and dangerous diarrhoea. Not 

 only, therefore, should the licking 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 ointments, it is necessary to remark, that they 

 are too apt to be smeared over the hair, without being ap-
