Fig. 123.—Cryptobraiichus japonicus (Great Japanese Salamander). 316 VENOMS Zaleski^ isolated from it a substance soluble in alcohol, insolublein ether, and with a very strong alkaline reaction, to which he gavethe narae salamandarin. This substance, which is better knownto-day as salajnandrine, has been studied afresh by A. Dutartre,^Phisalix and Langlois,^ and subsequently by Edwin and S. Faust.^ The action of this poison on the frog is characterised by a periodof violent convulsions, with general tetanic crises, followed by aperiod of paralysis, with arrest of respiration and complete muscularrelaxation. According to the quantity of poison absorbed, thisparalytic period may be followed by death, with arrest of the heartin diastole, or else by return to life, with more or less acuterecurrence of convulsions. S. Faust prepares salamandrine by pounding up whole sala-manders in a small quantity of physiological saline solution. Thethick pulp obtained in this way is filtered. One cubi
