    Artificial Tympanums for the Ear. (This Invention received Provisional Protection, but notice to proceed with the application for Letters Patent was not given within the time prescribed by the Act.) PROVISIONAL SPECIFICATION left by James Yearsley at the Office of the Commissioners of Patents, with his Petition, on the 19 th November 1856. « I, James Yearsley, of Saville Row, Saint James*, in the County of 5 Middlesex, Member of the Royal College of Surgeons, do hereby declare the nature of the said Invention for “ An Improved Method of and Instrument for Applying Artificial Tympanums,” to be as follows:— My present Invention then consists in attaching to a pellet of cotton wool a piece of silk or other soft thread of about three inches in length. I pass the 10 free end of the thread through a silver or other tube of small diameter until the cotton wool is brought against one end of the tube, where it is retained by the finger pressing on the thread which projects from the other end of the tube ; the cotton wool being then, or having been previously wetted in tepid water, is introduced at the end of the tube into the ear and moved about gently, 15 until the patient finds by improved hearing that it has reached the position intended for it to occupy. The tube is then carefully withdrawn over the thread, the cotton wool of course being left on the proper spot in the ear. So much of the thread as protrudes is next cut off or turned in the ear, when the operation is finished. Where desired, the tube may be formed with a small 20 hook at one end.
