dges of the sound horn are to be pared
thin, so that the swollen soft tissues may not overlap their borders.
With sharp scissors cut off all the prominent points on the soft
tissues, shorten the walls of the foot, and nail on a broad, plain shoe.
The foot is now ready for the dressings, and any of the many stimulating
and drying remedies may be used; but it will be necessary to change
frequently from one to another, until finally all may be tried.

The list from which a selection may be made comprises wood tar, gas tar,
petroleum, creosote, phenic acid; sulphates of iron, copper, and zinc;
chlorid of zinc, bichlorid of mercury, calomel, caustic soda, nitrate of
silver, chlorid of lime; carbolic, nitric, and sulphuric acids.

In practice I prefer to give the newly shod foot a bath for an hour or
two in a solution of the sulphate of iron made by adding 2 ounces of the
powdered sulphate to a gallon of cold water. When the foot is removed
from the bath it is dressed with oakum balls dipped in a mixture made of
Barbados tar 1 part, oil of turpentine 8 parts, to which is slowly added
2 parts of sulphuric acid, and the mixture well stirred and cooled. The
diseased parts being well covered with the balls, a pad of oakum
sufficiently thick to cause considerable pressure is placed over them,
and all are held in place by pieces of heavy tin fitted to slip under
the shoe. The whole foot is now incased in a boot or folded gunny sack
and the patient turned into a loose, dry box. The dressings are to be
changed daily or even twice a day at first. When they are removed, all
pieces of new horny matter which are now firmly adherent must be rubbed
off with the finger or a tent of oakum. As the secretion diminishes, dry
powders, such as calomel, sulphates of iron, copper, etc., may prove of
most advantage. The sulphates should not be used pure, but are to be
mixed with powdered animal charcoal in the proportion of one of the
former to eight or ten of the latter. When the soft tissues are all
horned over, the dressings should be continued for a time, weak
solutions being used to prevent a recurrence of the disease. If the
patient is run down in condition, bitter tonics, such as gentian, may be
given in 2-dram doses twice a day and a liberal diet of grain allowed.

CORNS.

A corn is an injury to the living horn of the foot, involving the soft
tissues beneath, whereby the capillary blood vessels are ruptured and a
small quantity of blood
