The Otological Research Laboratory of the Johns Hopkins University was established about five years ago for the purpose of studying deafness by the correlation of gross and microscopic changes in the middle and inner ear with auditory and vestibular tests for function made before death. The supply of temporal bones is obtained from the pathologic department of the Johns Hopkins Hospital and the Bay View division of the City Hospitals. These two institutions together have about 1,200 autopsies a year. Permission for a complete autopsy is not obtained in every case, but the laboratory receives each year about 275 pairs of temporal bones.

The clinical examination of the ear is not limited to patients with an obvious disturbance of hearing or equilibrium. The correlation in a
