    india-rubber bougies, and catgut strings {acoustic and tactile means of diagnosis). My ear-catheters are made of fine silver, cylindrical, straight, mches long, polished; at their one end well romided and formed like a beak, by bending three- quarters of an inch of then* length at an angle of 144®. At their other end there is a funnel, 10 lines long, and on the same level with the above-mentioned beak, an oval ring, which indicates the direction of this beak when introduced into the throat. Four’ ear-catheters of this description (see the woodcut), but of gradually increasing size^ are wanted in aural practice. The cahbre of catheter No. 1 corresponds with No. 1 of Charriere’s fihk’e (well known, I have no doubt, to all chfiurgical instrument makers); that of catheter No. 2, with Charrim'e’s No. 3; that of catheter No. 3, with Charriere’s No. 6 ; and that of catheter No. 4, with Charrim'e’s No. 7. Air blo^vn through these difterently-sized catheters increases in power in exact proportion to their increase in calibre—a fact of the greatest value in the diagnostical point of view. Before introducing one or the other of my ear- catheters, one smoothes its surface with one drop of olive oil. The patient, being seated on a chair, leans properly back, rests one of his arms on a table at his side, and blows his nose in order to clean and to moisten it. Standing now m face of the patient, one takes hold of the catheter with the thumb and two fore-fingers of the right hand, turns its beak upwards and its concavity to the patient’s face, puts the beak gently into one or the other nostril, proceeding with the instrument along the bottom of the nose^ and raising the catheter as soon as possible to a horizontal position, till its beak touches the throat.
