contains infective material, it is washed out with copious quantities of peroxide of hydrogen—­usually as much as six or eight ounces.  This is followed by injection of an ounce or two of tincture of iodin.  Even though the joint appears to be clean some tincture of iodin is used, as it checks the secretion of synovia and is, in every way, beneficial.  Care is taken to apply the iodin also to the surface immediately surrounding the wound.  The entire wound is then covered with a dusting powder composed of zinc oxide, boric acid, exsiccated alum, phenol and camphor.

This powder is used in abundance and the wound is then covered with a heavy layer of absorbent cotton and well bandaged.  This bandage is not disturbed for at least three days and may be left in place for a week.  In cases in which it is necessary to keep the dressing on for a week, or in cases where the patient is, through necessity, kept in quarters that are wet or unclean, the first bandage is covered with a layer of oakum which has been saturated in oil of tar and this in turn is held in place by means of several layers of bandages.  The bandages are also saturated with oil of tar.

In from one to two months wounds so treated, unless they are foot-wounds, will be ready to dress without being bandaged.  It is ordinarily unnecessary to dress foot-wounds oftener than every second week after the discharge of synovia has ceased.  When the wound has filled with granulation, a protective dressing is applied which is rendered water proof by the use of bandages covered with oil of tar.  The patient can now be turned out for a month or six weeks without disturbing the dressing.  After the removal of the bandages, the only treatment necessary is an occasional application of some mildly antiseptic ointment.

Except in nail pricks of the foot, occasioned by punctures, a five per cent tincture of iodin is injected into open joints, if the wound remains sufficiently open, and this treatment is continued so long as there is a discharge of synovia.  Surgical drainage is established if it is considered practicable and the remainder of the treatment is about the same as for wounds which are open.

Open joints occur in horses at pasture and are sometimes not discovered until several days or a week after the injury, and in some instances the wounds are filled with maggots.  The only difference in the treatment of these cases is that more time and care is taken in cleansing the wound, more curetting is necessary, and after cleansing the wound with peroxide of hydrogen, the joint is thoroughly washed out with equal parts of tincture of iodin and chloroform.  This is followed by the injection of a quantity of seventy-five percent alcohol and the wound is dressed and bandaged as already described.  At each subsequent dressing of infected wounds so treated less suppuration is noticed and the synovial discharge usually ceases in from one to two months.
