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 setin. 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.

may define it as a chronic inflammatory condition of the
