solution. This solution should be a little stronger than 
for flesh wounds. Make the solution by using a teaspoon- 
ful of carbolic acid to only a pint of water. After the 
cotton has been inserted a few times and withdrawn, each 
time a fresh cord being used and fully saturated, leave the 
last one in for a few hours and then repeat the treatment. 
This should be done three or four times each day. 
12. Drainage for the wound.—The main point in the 
treatment of nail puncture of the foot is to provide free 
exit to all matter that may collect, and to keep the parts 
clean. If this is done, the matter will not be forced to 
work out at the heels, and no separation or loss of hoof 
will occur. Often in case of a very severe wound the treat- 
ment acts slowly. In case proud flesh accumulates it may 
be burned away by a hot iron. After this operation has 
been performed, the cavity may be filled with balsam of 
fir and cotton placed over it, a piece of heavy leather 
fitted to the foot and held fast by the replaced shoe. This 
will usually end the difficulty. A veterinarian should be 
called for treatment of severe cases. 
13. Treating bruises.—In treating bruises a different 
procedure is necessary. The broken tissue is concealed 
beneath the skin and usually under the surface muscles. 
Bathing with water and acetate of lead—a quart of water 
and two tablespoonfuls of the acetate—will tend to lessen 
the inflammation. In time it may be necessary to open 
the swelling to let the pus out. After operaiing inject 
a mild antiseptic wash for cleansing, using one quart of 
water and a tablespoonful of chloride of zinc. If the 
swelling remains, apply twice each month a salve made 
by using a small amount of biniodide of mercury and lard. 
Wash occasionally, using the chloride of zinc solution.
