shaped darker blotches on the sides, and seldom exceeds three feet in length. It occurs in the Eastern and Middle United States, from Pennsylvania and Nebraska southward. It is a vicious and dangerous snake, striking vs^ithout warn- ing. The water-moccasin is dark chestnut-brown, with darker markings. The head is purplish-black above. It is found along the Atlantic and Gulf coasts from North Carolina to Mexico, extending also some distance up the Mississippi Valley. It is dis- tinctively a water-snake, being found in damp, swampy places or actually in water. It reach- es a length of over four feet, and is a very venomous snake, striking on the slightest pro- vocation. The common, harmless water-snake is often called water-moccasin in the Southern States, being popularly confounded with this most dangerous of our serpents. The poison of all of these snakes is a rather yellowish, transparent, sticky fluid, secreted by glands in the head, from which it flows through the hollow maxillary fangs. The character and position of the fangs are shown in fig. no. Remedial measures for the bite of poisonous snakes are first, to stop, if possible, the flow of blood from the wound to the heart by compressing the veins between the woimd and the heart; then (if the lips are unbroken) to suck the poison from the wound; next to introduce by hypodermic injection permanganate of pot- ash, bichloride of mercury, or chromic acid into the wound; and finally, perhaps, to take some strong stimulant, as brandy or whiskey. The crocodiles and alligators are reptiles familiar by Fig. 110. Dissection of the head of a rattle-snake; /, poison fangs; p, poison-sac.
