POISONOUS FISH. -- Old wife, crawfish, land crab, gray snapper, hyne, dolphin, conger eel, mussel, barracuda, smooth bottle fish, grooper, rock fish, Spanish mackerel, king fish, bonetta, porgee, tunny, blower, etc.
SYMPTOMS. -- In an hour or two, or much sooner after the fish has been eaten, a weight at the stomach comes, with slight vertigo and headache, sense of heat about the head and syes, considerable thirst, and often an eruption of the skin resembling nettle rash.
TREATMENT. -- Give a brisk emetic. After full vomiting an active purgative should be given. Vinegar and water may be drunk after the above remedies have operated, and the body may be sponged with the same. Water made very sweet with sugar, to which a little ether may be added, may also be drunk freely. If spasms occur, give laudanm.
POISONOUS SERPENTS. -- Copperhead, moccasin, viper, black viper, rattlesnake, water viper.
SYMPTOMS. -- A sharp pain in the wounded part, which soon extends over the limb or body; great swelling, at first hard and pale, then reddish, livid, and gangrenous in appearance, faintings, vomitings, convulsions, pulse small, breathing difficult, cold sweats, failing sight, and derangement of the intellectual faculties.
TREATMENT. -- Tie a string tightly above the wound, wash it well, apply a cupping glass, or let the person bitten suck the wound well if he can. If lunar caustic or butter of antimony are at hand, rub them well in, to the very bottom of the wound, or take a very small poker, or a steel used for sharpening knives; make the point of this red hot -- to a white heat, if you can -- and press this for a moment into the wound. This is not such a dreadful operation as it seems to be, for one moment's application is sufficient, and, if the steel is really hot enough, gives scarcely any pain at the time. Small doses of hartshorn may also be given, and if gangrene is threatened, give wine freely. In case of rattlesnake bite, give whiskey freely. Bibron's antidote and the Tanjore Pills may also be used, -- the latter carefully, as they contain arsenic.
