To avoid bleeding, which is frequentlyproduced by the immediate impact of the stiff nozzle upon the pituitarymembrane, the connection between the balloon and the nozzle is effected bythe insertion of a short elastic india-rubber tube. For some years past Ihave used in my practice the rubber balloon (p. 101) which is usually onlyemployed for catheterization, its nozzle being provided with a somewhatrigid india-rubber tube 3| cm. long (Luwenberg). The details of the method are the following : The patient, beingseated in a chair, takes a little water into his mouth—to facilitate.

If I introduce the extremity of the escape-pipe of a force-pump into thenose, half an inch deep, and compress the alee round it, and then perform an act ofswallowing while the compressed air rushes into the nasal cavity, I feel the air at thesame moment entering with force into both tympanic cavities, while the drop of fluidin a manometer, inserted into the external meatus, moves outwards. * The use of water is by no means absolutely necessary in all cases during theapplication of my method, which I often perform during a simple act of swallowing,the effect of an energetic act of deglutition being the same as that of drinking , however, the simple act of swallowing is less powerful, and not only isdeglutition in such cases materially faci
