DISEASES AND THEIR TREATMENT. 191 



In treating scratches, first give a dose of physic, or a few 

 bran mashes. 



CANKEB. 



This is a more aggravated form of thrush, often proving 

 very troublesome to manage. It is a continuation of the 

 thrush between the horny frog and the internal structures of 

 the foot, causing separation between them. 



Treatment. Cut away all the horn which has been sepa- 

 rated from the soft structures of the foot, and apply the 

 following ointment : Take equal parts of pine tar and lard, 

 melt over a slow fire, and add sulphuric acid very slowly 

 until ebullition (boiling) ceases, and apply to the parts. 

 The foot must be protected from dirt by a bandage or a 

 leathern boot. 



QUITTER. 



This is a formation of pus between the hoof and the soft 

 structure within ; a sore at the coronet or upper part of the 

 foot, which at first is a hard, smooth tumor, soon becoming 

 soft, and breaks, discharging quantities of pus. 



Treatment. Poultice the foot for several days with flax 

 seed meal. As soon as the hoof becomes soft, cut away all 

 loose portions, but no more, and inject with a syringe 

 either of the following once a day: Chloride of zinc, 2 

 drams, dissolved in a pint of water ; or, sulphate of zinc, 

 1^/2, drams, in a pint of water; or, nitrate of silver, 2 

 drams, in a pint of water; or glycerine may be used with 

 advantage. Before using the wash have the foot well 

 cleaned with castile soap and water. 



MANGE. 



Take the horse in the sun and scrub him thoroughly all 

 over with castile soap and water, then wash him well from 

 head to tail with gas water, in which put 2 drams white hel- 

 lebore to the gallon. He must now be put in another stall, 

 distant from the one in which he has been standing. Thus 

 treated, it rarely requires more than one washing to effect 

 a permanent cure. The harness should be thoroughly 

 scrubbed and put away for six or eight weeks. These pre- 

 cautions are necessary to success in this otherwise trouble- 

 some disease.
