The technical difficulties involved in an investigation of this kind invariably make the information obtained rather insignificant in relation to the amount of time and effort put forth. Experiments must be repeated many times before a dependable method can be developed, and even then an inevitably high mortality in the experimental animals persists Before consistent success can normally be achieved. The data upon which the following observations are based represents a series of chronic experiments carried out in the Laboratory of Otological Research at the Johns Hopkins in 1934, 14 in number, and a subsequent extensive investigation during the past year in the Otological Research Laboratory of the Abington Memorial Hospital. In the first group, partial and graded division of the auditory nerve was carried out under high binocular magnification. In all experiments partial or complete division of the nerve was considered successful only if the blood supply of the cochlea remained intact.
