Abstract
The ordinary aura speculum of either the round or the oval type has a sharp edge at its distal end, and unless used carefully may be painful on introduction into the canal. It tends also with time to become distorted in shape, while the Aural specula. thin edge necessary to a maximum lumen becomes still sharper. To make the speculum more comfortable for the patient, without at the same time lessening the visual field, I have modified both the round and the oval forms by the addition of an elliptic shoulder of spun brass flush with the distal end, applied with such a flat curve as to increase but little the outside diameter, and to avoid any liplike projection. Hence practically the same internal lumen is available as in the ordinary speculum, with more comfortable introduction and an added facility in pushing to one side cerumen and epithelial debris clinging
