London, Macmillan and Co., Ltd., 1924, 8°, XX, 253, (3) pp., 50 Fig., orig. Leinenband. First Edition! Of the models built to illustrate the theories of inner ear behavior, those of Max Meyer and George Wilkinson (1867-1956) and Albert Alexander Gray (1869-1939)received the most publicity and discussion during the 1920s. The essential feature of the theory of cochlea function of Wilkinson is that the fibers of the basilar membrane are differentiated by length, tension and mass, just like the strings of a muscial instrument. The scale of the model was not pertinent to the law of vibrating strings. Hence the model and the cochlea could be expected to follow the formula for vibrating strings as derived by Fourier. -cf. see: Audrey B. Davis and Uta C.
