    rupture of the membrane. The method of rarefaction recommended by Lucae with a fungoid-shaped balloon is too inconstant, and requires too much time. To Charles Delstanche we owe the ' rarefacteur' (p. 80), with which repeated rapid aspirations may be made. A frequent adjunct to thera- peutic methods is fomid in the ' masseur' (Fig. 82), lately invented by Ch. Delstanche, which consists of a metal tube 4i cm. long and 2| cm. in diameter, enclosing a smaller tube which acts like a valve to a syringe. The recoil of the valve which produces the aspiration is accomplished by a spiral spring between the valve and the bottom of the metal tube. This instrument has proved in many cases of great value in my practice. Lacking one of these instruments, the same object may be obtained by a rubber tube 30 cm. long, connecting an olive tip to fit hermetically into the external meatus, with a strong balloon, 6-7 cm. in size, or with the ordinary large rubber balloon. The aspiration is accomplished in this manner: The balloon is compressed and the olive tip inserted into the external meatus, when the balloon is allowed to slowly expand. This procedure may be repeated 4-5 times at one sitting. Earefaction of air in the external meatus is indicated : 1. In all catarrhs of the cavum tympani and Eustachian tube in which the membrana tympani is retracted. 2. In adhesions between the membrana tympani and inner wall of the cavum tym- pani. 3. After paracentesis of the membrana tympani to aspirate serous or mucous Fig, 82.—Masseur op exudate out of the cavum tympani into Chas. Delstanche. the external meatus. 4. To aspirate pus from the cavum tympani into the external meatus (E. Politzer) in cases where the injection of air by the tube is impossible, or does not succeed, and farther, in localized sup- puration of the cavum tympani which do not communicate with the tube. 5. In subjective noises in the ear, which often cease or are much diminished and become less troublesome after its use (Hedinger). Besides these, it often produces a noticeable subjective easing in the head and ear in middle ear catarrh which gives this treatment a special value in treating these diseases. 6.
