PROFESSOR Mygind presents a most interesting approach to the interpretation of the mechanical stimulus to the sensory cells of the ear as well as to those of the non-auditory labyrinth. He has first raised the old problem of "bringing harmony between the very broad mechanical and electrical reactions observable and the very sharply restricted areas of sensation actually resulting." That is, how can sharp discrimination between close frequencies be accomplished in face of the apparent broad response of the basilar membrane? Rather than involve secondary systems such as special "triggering action," presumably such as the funneling action of Békésy or the volley principle of Wever, Mygind prefers to reinterpret the entire hair cell stimulating process.

In this novel consideration a great many observations on the lateral-line organ and nonauditory labyrinthine system are reviewed, and the first argument is a rejection of the principle of shearing forces between the tectorial membrane
