324 DISEASES OF THE HORSE'S FOOT 



right round the diseased surface, the diseased part of the 

 bulb of the heel being divided from the sole by new horn. 



Three to four weeks later the diseased surface was gradu- 

 ally getting smaller, while in about six weeks it was quite 

 healed up, the last place to heal being a strip outside the 

 bar, between it and the wall, and a smaller spot on the 

 bulb of the heel. These healed up simultaneously, and 

 left the animal sound. 



3. (Treatment by Pressure, H. Leeney*). I was consulted 

 in the early part of last summer, before the dry weather 

 had begun, as to a farm-horse with canker in three feet. 

 Her shoes were in the 'disgruntle' condition we so often find 

 on farms, that, to give her a level bearing until I should 

 call another day with a farrier to help me to pack the foot up 

 in the old-fashioned way, I had the remaining shoes pulled 

 off. The case somehow dropped out of my list, and I 

 neglected to call, until asked one day to see something else. 



I then found that, under a pressure of work, the animal 

 had been used in the shafts of a farm-cart on tolerably level 

 ground, and when the dry weather had already set in. There 

 was a distinct improvement in all the diseased feet, and as 

 she was badly wanted I contented myself with rasping off 

 some broken crust, and supplied some caustic dressing for 

 use at night. Without shoes she worked continuously on the 

 dry and hard meadow-land for several weeks, and was 

 practically cured in something less than three months. My 

 astringent or caustic lotion may have had something to do 

 with the cure of the deep-seated parts, but the bare recital 

 of the case should be sufficient to show that it is all a 

 question of bearing, or nearly so.

Definition. — In describing this condition under the above 

 heading, we are following the lead of Mr. Malcolm. We 

 may define it as a chronic inflammatory condition of the 

 keratogenous membrane, usually confined to that of the
