=Treatment.=--Treatment of snake bite must be prompt if it is to be successful. It should consist of incision and drainage of blood from the part, in order to prevent diffusion into the rest of the body by means of the returning blood and lymph. Bleeding should be facilitated by cups or by sucking the wound. An elastic tourniquet should be applied around the limb near the trunk, the site of the wound freely incised, and the blood worked both ways toward the wound by “stripping” the member. If there be any known antidote to snake poison it consists of potassium permanganate or calcium hypochlorite (chloride of lime), applied locally in solution, the former sufficiently strong to have a marked color and capable of producing local irritation (1 per cent.). With these local measures, constitutional stimulation should be indulged by means of volatile and other stimulants. There is a popular fallacy in favor of inducing alcoholic intoxication. To do this is a mistake. Nevertheless, alcohol may be given freely, dosage being limited not by amount but by effect. Strychnine, digitalis, atropine, etc., will often prove serviceable. The tourniquet should be gradually released after being in use for two or three hours, and an assistant ready to antidote the poison which may then enter the system with the necessary doses of stimulants above mentioned. One-half grain of strychnine may be administered in divided doses, it apparently being an antidote to the snake venom. There is much reason from recent experimentation to expect benefit from serum therapy--_i. e._, by injection of serum from immunized animals who have been fortified by increasing doses of the snake poison. Calmette advises the use of 20 Cc. of serum from a horse which has been immunized by cobra poison. He believes the active poison of all venomous serpents to be essentially identical. Good results have been reported even after an interval of an hour. In this country, however, such treatment will be called for so seldom that there is not the hopeful outlook for the serum therapy of snake bite that there is in India. POISONING BY LIZARDS. A large lizard found in the southwestern part of this country and in Northern Mexico, known as the _Gila Monster_ (_Heloderma suspectum_), is credited with being a poisonous animal. The probability is that the bite is fatal to some of the lower animals and may produce more or less serious disturbances in man. Nevertheless there is little real evidence that this is to be considered in the same category with the venomous serpents above mentioned. POISONING BY SPIDERS AND SCORPIONS.
