||Brunton's auriscope was first described in an article which appeared in the Lancet in 1865.
This auriscope worked on the principle of a periscope: light from a candle or lamp was concentrated by a funnel and then reflected by a plane mirror set at an angle of 45' into the ear canal.
The mirror had a central perforation through which the examiner could view the ear.
Brunton's otoscope could be, and often was, fitted with a magnifying lens for the observer and could also be sealed with plain glass at the illuminating end.
It was thus possible to alter the pressure within by means of a small rubber tube into which the observer sucked or blew while observing the movement of the tympanic membrane, thereby emulating Siegle's pneumatic otoscope.
