By the use of a phase contrast microscope, the author examined the structure of fresh memb-ranous labyrinth of guinea pig.Observations were summarised as fallows:1) The inner and outer hair cells and their supporting cells were respectively separated from Organ of Corti by means of micro-surgical technique, and their fine structures were observed.2) The bassilar, reticular, tectorial and Reissners membarnes and vascular stria were respectively separated from cochlear canal. Their constructions were observed.3) Particularly, hairs of sensory cells were examined in detail. It might be stated from this observation that the forms and distribution of hairs are different in respective portions of the spiral turn of cochlea.The anthor concluded from the mor phological observation described above, that the hairs of sensory cells play an important role in the analytic mechanism of sound frequency in the inner ear.
