Page 145 - ... treatment of that organism. 1. Cutaneous. Rub the inoculum on the shaved and disinfected skin or make several parallel, superficial incisions and rub the inoculum into the scarifications with a sterile scalpel. See that no disinfectant remains on the skin before operating. 2. Subcutaneous. I. (a) Pick up the skin with the thumb and forefinger of the left hand and insert the needle through one side of the fold of skin thus made. Note. The point of the needle should not enter the skin on the other...
Page 123 - Duchenne) : — 1. ." In man whatever may be the direction of the currents, or the degree of vitality of the nerves they traverse, the same results are always produced when the conductors are applied to any portion over the course of the nerves, namely, muscular contractions and sensations.
Page 8 - Fig. 18. general rule, a plate machine is, for equal size, of far higher power than the cylinder. The arrangements of the latter are, however, simple, and are, perhaps, more easily managed by the uninitiated. There is also an advantage on the score of economy, as old cylindric machines are readily to be procured at low prices, and, as a general Fig.
Page 81 - As a means of diagnosis between actual paralysis of sensation and mere subjective anaesthesia, in which the tactile powers are unaltered. 3. As a means of determining the progress of a given case of paralysis for better or for worse.
Page 14 - If this does not readily appear at the first contact, repeat the opening and closing of the metallic contact quick or slow, and it will be decidedly manifested both by taste and sensation. When two metals are placed in contact direct, or by means of a connecting wire, and when these are placed in a liquid or liquids capable of acting upon the one more than upon the other, then that peculiar electricity is evolved that we term voltaic electricity, galvanic electricity, or galvanism.
Page 7 - If simply holding two /tawe^e-electrodes of an active battery respectively in the two hands of the patient, — or while one is thus held, the other is somewhere applied over the head, body, or limbs — or the patient is to be shocked, no matter how, — evidently but very little skill is demanded in the applications of electricity, and scarcely could it be termed an art.

When two metals are placed in contact direct, or by means of a connecting wire, and when these are placed in a liquid or liquids capable of acting upon the one more than upon the other, then that peculiar electricity is evolved that we term voltaic electricity, galvanic electricity, or galvanism. The original pile for producing this current was devised by Dr. Volta, an Italian physician, owing to the interpretation which this celebrated...

But he thinks neither of these ways should be resorted to in cases of paralysis of the portio dura, because from that point in the ear the feebler currents produce no effects on the muscles of the face ; while if we employ requisite currents to produce an effect on the face muscles, the electric stimulus is then inevitably conveyed to the superficial temporal, or to the auricula-temporal nerve from...
Page 15 - ... indispensable to the manifestation of electricity ; that voltaic, or otherwise called galvanic electricity, may be produced by any chemical action ; not only by the action of some liquid upon a solid, but likewise by the action of two or more dissimilar liquids upon each other ; or even by gases acting upon gases, liquids, or solids.
Page 82 - ... an inch equally well at the tips of the middle and third fingers of both hands ; the instrument aided in the determination of the diagnosis by showing that the numbness was purely subjective, and not the result of a true paralytic affection. The instrument is one of very simple construction, being essentially what is known to mechanics as a beam compass. It consists of a rod of bell-metal, four inches in height, graduated into inches and tenths of an inch. At one end is a fixed steel point; another...
