now and then the horse or pony so injured is worked on for days before 
anything is said about him being lame, grit and dirt works into the 
wound, the horn on the inside quarter where the injuries generally occur 
becomes softened, a disagreeable ichorous discharge squeezes out of the 
wound, the animal is very lame. In this state of affairs I often find it 
necessary to remove almost the whole of the quarter and sometimes a 
portion of the sole, when, after immersing the foot in warm water for a 
time, I place on the foot a round or bar shoe, seating it so that there 
shall be no pressure on the injured side, and dress over the parts either 
with Antim. Ses.Chlor. or AcidfNit., then apply tow over all the exposed 
surfaces, and' tie the foot loosely up; after a day or two remove the 
dressing and apply daily the Ung. Zin. Sulph. Co. I have frequently 
found in these cases that a portion of the os pedis has been injuried, or 
necrosis takes place as the result of the injury, and in many cases I have 
removed large portions of the bone which have become detached, and 
after scraping away any spiculae that may remain, and dressing in the 
manner mentioned, the cases have done well. Occasionally we come 
across cases where a waggon wheel has run over the front of the foot not 
cutting the horn, but crushing and bruising the parts beneath. In these 
cases the annual suffers great pain, the limb is continually drawn up 
under the body, the animal flinches on the least pressure to the foot, 
the laminse are generally so much injured that extravasation of blood 
takes place, and the consequent swelling of the soft structures contained 
within the unyielding hoof necessarily causes the most excruciating pain. 
Recently I have had a very severe case of this kind, in which, after some 
days had elapsed, pus formed and made its way out at the coronet, 
although I had before removed a portion of the sole. Finding that it was 
partly underrun, I now passed the probe upwards, and discovered that a 
portion of the os pedis was exfoliating immediately in front and about an 
inch below the coronal process. I thereupon removed the horn from the 
wall to within half an inch of the coronet, and with the forceps took 
away about half an inch of the pedal bone. After dressing with solution 
of carbolic acid and Tr. Myrrh Co., and placing pledgets of tow over all, 
I had affixed to the foot a shoe having a clip at each side of the toe, and 
although for a time I was troubled with luxuriant growths from the 
exposed laminae, which had to be kept down by application of Antim. 
Ses. Chlor. and pressure, the case has progressed satisfactorily. 
Corns .—Bruise of the inner angle of the sole of the foot between the 
wall and bars, more often on the inside and almost always confined to the 
fore feet, due to undue pressure on the heels, generally caused by the shoe, but 
may arise from other causes, as by a stone becoming fast between the shoe 
and frog, the pressure causing bruise and rupture of small blood-vessels 
and consequent of blood, which percolates through the fibres of the horn. 
Should the bruise be severe and the cause not removed, or the injury not 
attended to, suppuration is the result, pus forms and unless an outlet is 
given to it by the removal of the horn it burrows upwards through the 
soft structures and makes its exit at the coronet. The more simple 
cases of bruise to the foot called corn are easily got rid of by removing the 
cause and poulticing the foot for a short time, should the cause, as is too 
often the case, be the result of a wrong system of shoeing, viz. the shoe 
being seated or bevelled on all the sole surface except where it comes in 
contact with the heels. Thus, you will find that the only bearing the 
sole obtains is at its weakest parts, viz. the heels, the wall of the foot 
carrying all the rest; this unequal pressure is, in my opinion, the most 
frequent cause of corn. The treatment of those cases of corn in which 
suppuration has taken place is often very troublesome. I commence by
