The result of the use of salines was a diuresis varying in the promptness of its appearance and in its amount. Those animals in which diuresis was limited at first and then increased generally recovered, while those in which diuresis was not established perished. The poison used was found in the urine of those which died and also those which recovered. The author succeeded in rescuing animals poisoned by alcohol, strychnine, chloral, and aconitine. With morphine, curare, and hypnone, the method of elimination failed, although ten per cent. in quantity of the body weight of the animal was used in the saline injection. With aconitine, diuresis was not always established, and when it failed the animal died in convulsions.--_Centralblatt fur die Medicinischen Wissenschaften, December_ 18, 1886. * * * * * A catalogue, containing brief notices of many important scientific papers heretofore published in the SUPPLEMENT, may be had gratis at this office. * * * * * THE SCIENTIFIC AMERICAN SUPPLEMENT.
