PHYSICAL MEASUREMENTS OF AUDITION 167 The theory of maximum amplitudes was first put into definiteform by Gray in It assumes that the position of maximumamplitude of the basilar membrane varies with the pitch of the stimu-lating tone. Although a considerable portion of the membranevibrates when stimulated by a pure tone, the ear judges the pitchby the position of maximum response of the basilar has shown that some action of this sort must take place due tothe dynamical constants It is an amplification of thistheory that I desire to propose as the one which most satisfactorilyaccounts for the facts. When a sound wave impinges upon an ear-drum, its vibrati
