The first procedure was the removal of every particle of diseased horn 

 witii the drawing knife, laying the horn serreting membrare bare all over. 

 The paring of the diseased horn should lie commenced at the part of the 

 foot most dependent when it is held up, so tliat the unavoidable bleeding 

 will be below the part still to be operated on. If this simple plan is 

 not adopted, the removal of all diseased growth, on which success almost 

 entirely depends, will be a matter of considerable difficulty. The e.xposed 

 surface, especially tlv clefts of the frog, was then dressed with liquified 

 crystals of pure carbolic acid. The horse was then placed in a shallow 

 foot bath of partially slaked lime, the consistence of thin paste, and al- 

 lowed to stand in it fox from four to five hours daily for a week, his feet 

 being dressed every alternate day wdth carbolic crystals. At the end nf this 

 time it was noticed that those portions of the frog and sole which had 

 received pressure were much less congested and swollen ; there was an 



absence of fungoid growths and cheesy horn, and the surfaces were har- 

 dened over and healthy in appearance. On the other hand, the sides and 

 bottom of the V-shaped cleft between the frog and sole, 00 wdiich no 

 pressure had been exerted, were in almost as bad a state as ever, except 

 that the foulness of the discharge was less marked, and evidently of a less 

 irritant character. Taking the hint from this casual observation, it was 

 speculated that the application of an even pressure toi every part of the 

 affected surface would have a salutary effect. Accordingly, a set of bar 

 shoes, dished so as to rest wholly on the snund wall, was made and ad- 

 justed, the bar crossing from one heel to the other. The diseased surface 

 having been thoroughly cleansed, painted with carbolic and dusted with 

 zinc oxide, a plaster-of-Paris cast was run in level with the <:rround
