In using this apparatus for the treatment of diseases ofthe ear, the catheter should be carefully introduced throughthe nose, and placed in position. Then, while the diagnostictube is placed in the ear, the hard-rubber tip should be in-serted in the catheter, and air alone forced through to deter-.

Daring this experiment the cathetermay be held in position by clamps for that purpose, or maybe held by the fore and middle ringers of the left hand, whilethe thumb of the same hand presses on the piston, the otherhand being used to work the air-bag. It is well to have a small round opening made in the air> 308 politzers method. bag, as at C; while the air is being forced out this may beclosed by the finger, which then being removed, the air-bagquickly fills again. It may be said in general terms that the use of spray ofastringent fluids to the Eustachian tube, is chiefly of value inthose cases in which the evidences of catarrh, or increasedsecretion, are strongly marked, while fluids are to be em-ployed in the tympanic cavity,
