The difference (g t] would express the time consumed by the torpedo between the excitation of its nerve and the dis- charge. By varying the experiment, as we have done for the motive nerves (page 43), we obtain the measure of the rapidity of the electric nervous agent, and that of the lost time in the torpedo apparatus.* Finally, in order to measure the duration of the electrical action, we had recourse to a method which consists in col- lecting this discharge during a very short time (l-100th of a second) to send it to the frog sii/nal, and varying gradually the instant at which the electricity of the torpedo was collected. It was thus ascertained that starting from the point (/.) one might, during 1 -1-lOOthsof a second, obtain a series of signals from the frog—t', t", t'", t"", but that beyond that time the frog gave no signals, thus proving that the discharge had terminated. \Ve have not been able to follow out farther the compari- son "T Hie electric with the muscular action; but, according to the result, already furnished by experiment, we can foresee ' Deprived iif appropriate apparatus, we have Leon olili^od to construct for oursehi > a kind <if registering instnimriit which should measure short int«T\.ils "if time with snlliciciit precision.
