The second method of healing, namely, by granulation, which is, however, the manner in which most wounds in animals heal, takes much longer. In punctured wounds of any depth healing necessarily takes place in this way only, and the treatment should be directed largely to alleviating pain and moderating inflammation.

After-treatment and dressing of wounds.—The dressing of wounds is one of the most important branches of veterinary surgery, and one of the most constant difficulties that the practicing veterinarian has to contend with lies in the lack of cooperation on the part of owners in the care and attention in the after-treatment of wounds.

In summarizing the treatment of wounds, the following recommendations should be observed: wounds must be cleansed and kept clean, using antiseptic solutions which do not produce irritation, and applying the solutions with a syringe or with clean pieces of absorbent cotton. Bleeding should be stopped before the closing of the wound by sutures or bandages. An opening at the bottom of all wounds except small superficial wounds should be provided as a drainage outlet for the escape of wound secretions or pus if it should form. The edges of wounds and the muscles involved in the wound should be kept as quiet as possible during the process of healing. Every wound should be protected by a sterile or antiseptic dressing whenever it is possible to retain a dressing in place. Dressings should be changed when it is apparent that they have become drenched with wound secretions or pus, or have become disarranged or too loose, permitting dirt to enter between them and the skin. If swelling appears beyond the edges of a bandage, it is an indication that it is too tight and it should then be removed and again applied.

The hands of the operator and all instruments and dressings coming in contact with a wound at any time should be made as clean as possible by the use of antiseptics.

Barbed-wire cuts.—We have specified these simply because in some sections of the country there is a fixed idea that there is a specific poison in barbed wire, causing injuries which require treatment differing from that which is applicable to ordinary wounds. Barbed-wire cuts differ from ordinary wounds only in the parts being often lacerated and torn, and the treatment already indicated for wounds of that description is applicable to them.

CASTRATION.

Castration consists in the removal of the essential organs of generation, and is performed upon both the male and the female. In the male the organs removed are the testicles and in the female the ovaries.

CASTRATION OF THE MALE.

Castration in the male is performed for several different purposes. It may be necessary, as is the case in certain diseased conditions of the testicles and in strangulated hernia, but the usual object of the operation is to enhance the general value of the animal. For example, if the animal is intended for burden, the operation will better fit him for his work by so modifying his temperament and physical condition that he may easily be controlled by his master. Again, if he is merely to be used for beef purposes, the operation will improve the quality of the flesh and cause an added development of the most valuable portions of the dressed carcass.
