The treatment of Lieutenant Rose was commenced at about the end of September, at which date the disease extended from the toe on one side of the foot right back to the heel, involving the sole, half of the frog, and the bulb of the heel.  One week after treatment the diseased surface was drier, and granulations were more healthy.  At the expiration of a fortnight the new horn had commenced to grow from the wall, and also from the frog, 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 gradually 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 [A]).  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.

7.  SPECIFIC CORONITIS.

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 coronary cushion, the ergots and the chestnuts, but sometimes extending to that of the frog and the sole, characterized by a malsecretion of the affected membrane similar to that observed in canker.
