Auroscope (inspector auris), 1825. Designed and drawn by Thomas Buchanan. For a cross section of this instrument and an explanation of component parts, see L0035325. Buchanan wrote of it: 'As I intended this instrument solely for the inspection of the meatus auditorius externus, so I have thence called it an Inspector Auris; a term which implies this special use, and for which it will be found well adapted, by all those who may have extensive practice in treating diseases of the human ear.
