An elastic tube, about eighteen inches in length, tipped with ivory at both ends, one extremity of which is inserted into the external meatus of the patient, and the other into that of the medical man.) 1853Sir W. Wilde Pract. Obs. Aural Surg. 113.
2. An optical instrument for inspecting the cavity of the ear.
1853Sir W. Wilde Pract. Obs. Aural Surg. 113 Otoscope..also applied to a form of speculum auris. 1884M. Mackenzie Dis. Throat & Nose II. 243 Brunton's otoscope..consists of a metallic tube provided with an eye-piece. Into this tube a funnel opens at right angles, through which the light is made to fall on a perforated reflector, which throws the rays through the distal part of the cylinder into an ordinary ear speculum.
