In order to verify the calculated velocities, the author observed with two beam oscilloscope the phase differences between the cochlear microphonics from two paris of electrodes which were inserted into the scalae and apart each other about 2 to 1.4mm.along the cochlear turn while the cochlea was stimulated by pure tone.The velocities of the progreesing wave were calculated from the phase differences obtained from the authors observation.The progressing wave decrease in velocity tlong the basilar membrane and their initial velocities are also diffrernt with the frequencies of progressing wave i.e.the progressing wave of high freq- uency are smaller in velocity than those of low frequency.The chrnging rate of velocity of the progressive waves in the cochlea of guinea pig is comparable with that of the human cochlea which has been observed by Bekesy, and the calculated velocities by various authors.In addition, the vibratory mchanism of the basilar membrane can be discussed from the authors observational data.
