Pyroligncous acid, ~} 



Linseed oil, £ . of each equal parts. 



Turpentine, ) 



Mix ; let the heels first be washed with lukewarm water and 

 castile soap ; after wiping them dry, apply the mixture. Re- 

 peat night and morning. 



In order to keep down morbid granulations — denominated by 

 some " proud flesh " — the parts may bo sprinkled daily with 

 one of the following articles : — 



Powdered bloodroot, 

 " burnt alum, 

 " bayberry bark. 



Put on a good coating of one of the above articles ; cover the 

 sore with dry lint, and apply a bandage over all. It should be 

 borne in mind that bandages should always be dispensed with, if 

 possible ; for they invariably irritate and inflame whatever parts 

 they are applied to. This is owing to the high state of sensi* 

 bility in the skin of the horse. 



HARDENING OF THE SKIN. — {Induration.*) 



Hardening of the skin generally takes place in consequence 

 of pressure from some portion of the harness ; it often occurs, 

 however, from laceration of the integuments and sub-cellular tis- 

 sue ; by the calkings of the animal's shoes } and we sometimes 

 find that it is the result of fungus, or morbid growths, after they 

 have been removed by caustics. An excellent application for 

 these indurations is, the acetate of cantharides, prepared thus: — 



* Induration is an abnormal increase in the consistence of an organ or part, 

 and may exist under various circumstances. It may be owing merely to a de- 

 ficiency of blood in a part, in consequence of which its denser particles are 

 more closely aggregated, and therefore offer an increased resistance. There 

 are various parts of the animal structure which are often the seat of indura- 

 tion. The lungs, for example, in consequence of previous inflammatory action, 

 become hepatized : this is identical with induration, and is owing to the deposit 

 and coagulation of that portion of the blood known as fibrin. The liver now 

 and then becomes the scat of a fibrinous deposit ; the organ first enlarges, 

 but afterwards gradually contracts and hardens : as it is reduced in size, it be- 

 comes hard and tough ; here we have schirrus of the liver — induration. Other 

 varieties of interstitial deposit are known to the profession ; and the reader, if 

 disposed, can also learn what is known of this branch of pathology from stan- 

 dard works.
