The External Ear as a Means of Identification

By this short address, illustrated by lantern slides, I hope to bring before our Society a subject worthy of discussion, inasmuch as it adds another aid in criminal identification which has for many years attracted the attention of criminologists at home and abroad. At the outset I must confess that my interest in the configuration of the ear has not been born of a criminological quest; but owing to frequent uncorroborated assertions that tumours and cancer are hereditary, I have paid for years close attention to the study of the ear-not as an aural surgeon-to the configuration of the external ear, being under the impression that an organ of such multiplex units and complex development, in relation with which defects are common but cancer rare, would afford valuable information along these lines.
