Treatment. The treatment is of two kinds, preventive and cura- 

 tive. Preventive treatment consists in changing the animals to dry, 

 clean quarters, exposing contaminated grounds and stables to sunlight ; 

 disinfect with Bichloride of Mercury solution, i to 500, cart away all 

 loose litter and excrement. Curative treatment consists in, first, 

 thoroughly cleansing the affected part, which is usually the cleft of 

 the foot. Curette away the diseased tissue. If the pus has burrowed 

 deep under the horn this must be cut away with a knife, which" should 

 be done only by a competent surgeon. After all the diseased structure 

 has been removed dress antiseptically with Creolin. If on the more 

 dense structure of the foot, it may be used undiluted, but on sensitive 

 parts dilute, one half ounce to a pint of water. They should be 

 dressed more or less frequently according to the severity of the case. 

 Should the animals suffer great pain they should be placed in slings, 

 subject to the dictation of a competent adviser. If Creolin is not con-, 

 venient I^ysol may be used instead, or Bichloride of Mercury, i to 

 1,000. Strong acids should not be used. Preparations of tar which 

 tend to make a coating are dangerous.
