Remembering that the diameter of the Eustachiantube varies from three quarters of a millimetre to two milli-metres, the size of this cotton pledget should certainly not ex-ceed the last-named dimension, and when used for the firsttime it is well to make it considerably smaller than this. Theopposite end of the wire is bent at a right angle at a point oneinch and a half from the outer funnel-shaped extremity of thecatheter. This, then, enables us to estimate the distance thatthe bougie has passed into the tube at any time.
