THB SKIN. 241 



complication is again serious and these must be scraped or portions of 

 them removed. la cases where the tumor is large and hard, yet not 

 defined so as to admit of extirpation with the knife, make a shallow 

 incision under the skin, over the center of the tumor, and, inserting 

 twenty to thirty grains of powdered arsenic wrapped in a single layer 

 of tissue paper, let it remain. In about ten days a deep slough 

 with an ugly granulating wound will have taken place, but this will 

 gradually close as healing progresses. Finally, as will be seen, the dis- 

 order is generally curable though requiring patient treatment. The 

 sinuses must be opened at the extremity and kept open, the first treat- 

 ment being caustic injections or applications applied once or twice; then 

 mild astringent antiseptic washes. These complete the cure. Where 

 the sinuses are so directed that counter openings cannot be made the 

 case is generally hopeless. 



Should the fistulse break out after having healed it is caused by 

 particles of diseased tissue remaining, and should a small abscess form it 

 should be injected with a solution of sulphate of zinc, twenty grains to 

 the ounce of water, every second or third day until entirely healed. 



Grease. This is a filthy disorder indicating neglect. Its pre- 

 vention is easier than its cure. A white leg is more subject to the 

 disorder than one of another color. Cutting the hair from the heels of 

 the animal and thus exposing them is another cause of Grease. The 

 earliest symptoms are enlargement of the legs with fevered skin ; 

 the hairs seem to stand on end and project straight outward. Then the 

 part begins to exude a thick, oily moisture ; this gives the disease its 

 name. The secretion is very offensive. This is accompanied by lame- 

 ness. 



The treatment consists of thorough cleansing with warm water and 



Castile soap and a thorough saturating with the following solution : 



J pint of Animal Glycerine, 

 i ounce Chloride of Zinc, 

 6 quarts "Water. 



This should be applied by saturating heavy cloths and laying them 

 upon it, constantly changing the cloths until the surface is thoroughly 

 cooled. Should the trouble have reached the ulcerating stage substi- 

 Irute the following stronger solution : 



1 pint of Permanganate Potash or Phosphoric Acid and 



6 quarts of. Water applied in the same way.
