ance, should be visible on the podophyllous tissue. A dressing 
is then applied of tincture of aloes, or a weak solution of iodine. 
At a later period the dressings are changed at intervals of about 
eight days, and an application is made of pulverized sulphate of 
copper, in order to facilitate the drying and hardening of the soft 
hoof. Baths of sulphate of iron, with a small portion of sulphate 
of copper, are of service in promoting-and hastening the cicatri¬ 
zation. 
About the thirtieth or fortieth day after the extirpation of 
the cartilage, the animal may be put to light work. But three or 
four months, if not a longer period, must elapse, before it will be 
safe to task him with heavy labor. Towards the end of the as¬ 
signed term he should be fitted with a bar shoe, shortened on the 
side where the quittor has existed. If the dressing is skilfully 
applied and proper care is exercised, the diseased foot may bo 
sufficiently protected, and the animal made to resume his work 
with safety. 
In time, the portion of hoof secreted by the coronary band 
unites with that of the podophyllous tissue, and after a few 
months, no remains of the operation are visible. But if the coro¬ 
nary baud has ulcerated; if the skin has been divided; if by 
contact of the firing iron, or application of caustics, it has been 
destroyed; the quarter then presents irregularities, and some¬ 
times divisions, which may be of long continuance, and give rise 
to a lameness which may, perhaps, become permanent. This 
danger indicates the necessity of exercising the utmost skill and 
caution in operating, in order to avoid possible injuries to the 
coronary band. 
Several modifications of the ordinary mode of operation have 
been proposed. Some have had for their principal object, the 
prevention of the extraction of the hoof, with a view of thus re¬ 
turning the animals to their work at the earliest period practica¬ 
ble. It is thus that Hazard, Junior, proposed to make a crucial 
incision upon the skin covering the fibro-cartilage; the four flaps 
being so dissected to expose it, and then removing it with the 
sage knife. In this process, the extirpation of the entire carti¬ 
lage becomes extremely difficult without inflicting injury upon 
the lateral ligaments and the synovial capsules.
