The toe is shortened as far as possible, without cutting it too thin 

 or tender, and the foot levelled alike from side to side and from 

 behind forward. Any horn.that has been underrun, and separated 

 from the quick, must be carefully pared off and the edges of the 

 sound horny wall bevelled to a thin elastic margin, which will 

 not press in and irritate the tender parts. All moderate cases 

 will now be ready for the antiseptic caustic dressing. 



For slight and recent cases with no underrun horn, a foot-bath 

 may be used. A watertight wooden trough is made four inches 

 deep, filled with a solution of copper sulphate (3:100), or carbolic 

 acid (5:100), or freshly prepared chloride of lime (4 ozs. to the 

 gallon), and the sheep are driven into this and left to stand there 

 for two minutes. On leaving the bath they should be run into 

 an uncontaminated field or disinfected yard or pen. The bath 

 may be repeated the second day or oftener if it seems requisite. 

 If a bath cannot be secured, individual dressing with a hair brush 

 or cotton swab dipped in the disinfectant liquid may be substi- 

 tuted. One man throws and holds the sheep on its rump, and 

 separates the hoofs one after another, while the second cleans 

 the interdigital space with a cloth or with water and soaks it and 

 the coronet with the disinfectant. In cattle with the hind feet 

 attacked, it is often convenient to have the leg lifted and carried 

 backward by two men holding a smooth, round piece of wood, 

 like a stout fork-handle, in front of the hock while a third person 

 dresses the foot. The same agents may be employed. Often a 

 dilute sulphuric acid (1:4), or antimony chloride, will operate 

 well. 



In the more advanced cases with extensive sloughing and the 

 formation of fistulse, the treatment must be more thorough and 

 persistent. After removal of all horn that can in any way prove 

 irritant, a thorough soaking with cupric sulphate (3:100); or 

 with cupric sulphate (3:100), lead acetate (3:100) and carbolic 

 acid (3:100), may be followed by packing of wood tar between 

 the hoofs and on all raw surfaces, maintained in place by a 

 bandage tied upward and around the pastern. In particularly 

 bad cases an initial treatment with peroxide of hydrogen is in- 

 dicated, as this agent is specially destructive to the anaerobic 

 microbe. When healthy granulations have started it may be re- 

 placed by one of the other antiseptic dressings. Or again, aniline
