In the absence of this radical measure muzzling should be enforced for a year in any locality where a case of rabies has occurred, and every dog should wear a collar with the name and residence of his owner inscribed on it. All stray dogs and all unmuzzled ones should be summarily shot. Dogs and cats that have been bitten by rabid animals should be destroyed or shut up in cages for six months under veterinary supervision. Imported dogs should be similarly secluded. Dogs that have bitten animals or men should be shut up for ten days under supervision, when, if rabid, the animal will develop unequivocal symptoms. _Treatment of bites._ Absorption from a wound in a limb may be prevented by applying a tourniquet. Wounds on the body may be cupped, or sucked through a tube. Or the wound may be wrung to encrease the flow of blood. As soon as possible it should be thoroughly cauterized. A hot skewer, a Paquelin cautery, a stick of silver nitrate or zinc chloride or caustic potash or a crystal of cupric sulphate will meet this end. If liquid caustics are to be employed they can be applied to all parts of the wound by means of a pipette, a glass tube, or swab. With thorough cauterization shortly after the bite there is practically nothing to fear, and even if it has not been applied for hours after, it is still valuable in destroying the poison left in the wound from which a continuous infection of the brain, by the transmission of the unknown germ and its toxins, would otherwise take place. It has besides in the human being a good moral effect against lyssophobia by giving the bitten person a certain sense of protection. _The Pasteur Method._ This is based on the fact that the spinal cord of the tetanic rabbit when removed aseptically, and kept _in vitro_ in a dry atmosphere, loses in virulence day by day, until on the fourteenth day it is harmless. To render the air more drying, caustic potash is introduced into the flask. The culture of the poison in rabbits intensifies its virulence, until the virus becomes the strongest known and when inoculated subdurally, reduces the incubation to six or seven days. In Pasteur’s early experiments he began injecting the emulsion of the cord desiccated for 14 days, following with that of the 13th day, and so on to that of the 5th. It was soon found that this was comparatively ineffective when inoculation had been made with a strong virus or in a large dose, and the treatment for such cases was modified to what is now known as the intensive method. The weaker forms of the virus are given at shorter intervals on the first days of treatment, and the stronger forms repeated again and again, and, in place of a 15 days, course of treatment, this is extended to 21 days. The following table illustrates the course:
