Exposure to cyanide represented by the time between arrows. First ten minutes skin exposed to Ringer's solution alone. pH values used were and Abscissae represents the exposure in minutes and the ordinates the in volts. The same concentration of cyanide was used in each series (M/250). The "cells" were placed in Ringer's solution for ten minutes, then removed; one series was placed in a solution of HCN in Ringer's solution at a pH of and the other series at a pH of Potentiometer readings were taken every minute for 45 minutes. Again it is evident from Fig. 14, that there is greater stimulation and less toxicity under alkaline than acid conditions. In either case the initial stimulation was not as pronounced as in the experiments when borax buffer solution was used. It is, how-.
