so as to excite the bronchial and laryngeal muscles;following this it acts centripetally upon the phrenic nerve, and uponthe great sympathetic. The excitation of the latter is able to modifythe vaso-motor activity of the vessels of the medulla oblongata and therespiratory centres. The results were found to be very favorable inessential asthma. II. Otology. Auditory-Nerve Deafness. This is best treated by the bifurcated electrode and the battery cur-rent, using the cathode to the ears. Gradually vary the current byemploying a rhythmic interrujjter, or by turning the current on and offwith the current collector. Ten milliamperes is the maximum. Seancesof 5 or 6 minutes are long enough. Apply to both ears simultaneously,so as to prevent vertigo. Use electrodes of a one-inch surface. Place asmall pad of moist absorbent wool between the electrode and the skin,because, the electrode being small, the density of the current is great.One variety of the double ear electrode is shown in Fig. 55.

The theory on which the experiments were based wasthat ulcerous conditions in the ear might be treated electrically, similarlyto the same conditions elsewhere. An electrode with a long, narrowextremity, covered with a little cotton, was inserted into the auditory 1 Le Bulletin Medicale, February 21, 1906. 112 ELECTEO-THEEAPEUTICS. canal through a rubber speculum, the canal being filled with tepidwater. The electrode is usually connected with the negative pole of thegalvanic current, though sometimes with the positive. The circuit iscompleted by the hand of the patient holding a sponge electrode, or rest-ing on a stationary electrode. Weak currents and short applications areto be employed, while some form of rheostat is indispensable. Tinnitus Aueium. Subjective noises can sometimes be dispe
