The fifth, at the supraorbital foramen, at the infraorbital foramen, at the mental foramen, on the side of the tongue.

It is as much if not more serviceable in this way than is the current derived from the secondary induction coil of many turns. Apostoli and others have borne strong testimony to the fact that the greatest success they have attained with this form of current has been in allaying the pains that occur in connection with the pelvic organs. The pains caused by uterine inflammation, pelvic cellulitis, ovaritis, salpingitis and congestion...

The pectoralis major from the 6th, 7th, 8th, and 1st dorsal. The pectoralis minor from the 7th, 8th, and 1st dorsal. 76. The Dispersing Electrode. — In investigating the electrical reactions of nerve and muscle, the surface area of the active electrode should be small so that it can be adapted to all surfaces....
Page 38 - Francaise d'Electroth^rapie, of January, 1899, and later in the Electrical Engineer of March 4. Plate XXXI illustrates the technique of applying the wave-current to the ankle-joint with a metallic braid as an elec trode, while Plate XXXII illustrates the same current applied to the spinal column by means of a sheet-lead electrode 20 inches long and 1£ inches wide, and Plate XXXIII illustrates the wavecurrent applied to the soles of the feet by means of the brass plate electrode. The electrodes are...
Page 37 - The general results of our researches may be thus summed up : 1. A slight fe-eling of drowsiness. This sometimes began to be perceptible shortly after the electrodes were applied, increased up to a certain point, and continued for some little time after the seance was over. In many cases it is not observed until the lapse of five or ten minutes after the stance. The feeling, which was by no means constant, was usually so slight that it might not have been observed, had...
Page 33 - EFFECTS OF FARADIC CURRENTS. 24. We shall study the effects of faradic currents on (1) motor nerves and striated and non-striated muscles, (2) sensory nerves, (3) vasomotor nerves, (4) nutrition. The extra-current of the primary coil, the so-called primary induced current, has the same direction as the battery current, but differs from it in having greater quantity and higher EMF It is therefore a unidirectional induced current and possesses in some degree the properties of the galvanic current....
Page 42 - Standard Electrostatic or Influence Machines. — A summary of modern opinion on the action of static currents may be obtained from the following abstract taken from the report of the committee on "Standard Electrostatic or Influence Machines," presented to the convention of the American Electrotherapeutic Association, and published in the "Times and Register," December 29, 1894: The physiological effects of static electricity are pretty much all that are produced by electricity. It sets free the...
Page 109 - On testing with litmus solution the reaction of the froth at the negative pole is alkalin and that at the positive pole is acid in reaction. The extent of destruction at each pole with a given currentstrength is of much interest in the treatment of tumors. Doctor Massey has made the estimate that 200 milliamperes concentrated at the ^-inch exposed end of a negative needle will destroy an area of this length and J inch in diameter in the muscular tissue of the cadaver, if passed through for 2 minutes....
Page 79 - The inlernal popliteal ncrce, in the popliteal space, and to the inner side of the tendon Achilles. In the face: 11. The facial, through the cartilage of the lower surface of the meatus auditorius. Its chief ramifications can be reached where they emerge from the parotid gland. Erb chooses for stimulation three main branches of the facial: (1) for muscles above the palpebral aperture; (2) for those in front of the upper jaw, between the orbit and the mouth; (3) for muscles of the lower jaw.
Page 79 - At a spot 1 inch above the clavicle and a little externally to the posterior border of the sternomastoid, immediately in front of the transverse process of the sixth cervical vertebra, a simultaneous contraction can be produced in the deltoid, biceps, coracobrachialis, brachialis anticus, and supinator longus.
