Abstract
JOHANNES MULLER, one of the greatest physiologists of last century, when considering the time factor in nervous processes, was so impressed with the inherent difficulties of the question, that he said, “We shall probably never attain the power of measuring the velocity of nervous action, for we have no opportunity of comparing its propagation through immense space as we have in the case of light.” As is often the case, when the forecast is darkest light is near. As it has in the case of determining the velocity of a nervous impulse by Helmholtz, so it has in the synchronisation of the kinematograph and phonograph. The question of synchronisation of a camera and a talking machine is a problem that attracted the attention of Edison himself from the time of his invention of the kinetoscope, an instrument, however, in which only one person at a time could see the moving picture.
