A MANUAL
OF
DISEASES OF THE NERVOUS
SYSTEM.

Within the past few years the treatment of Diseases of the Nervous System has grown up into a recognised speciality in the Medical Profession. Recent investigations, physiological, clinical, and pathological, have cast a flood of light upon its study, and it possesses—as a separate field of practice—Special Hospitals, and a voluminous and rapidly extending literature.

Under these circumstances the Author, although fully conscious of the extreme difficulty of presenting, within a small compass, an adequate view of our present knowledge, feels that a concise introduction to neuro-pathology may not be unacceptable to students and junior practitioners. It will be his endeavour to give the results of the best work by the many distinguished physicians, both English and Foreign, who have so completely made this department of medicine their own; to impart as much practical information as possible; to give an analysis of the principles which ought to govern our treatment of diseases of the Nervous System; and to direct especial attention to the importance of early diagnosis. He hopes to omit nothing really essential, and to make the work a safe and trustworthy guide to the practice of the speciality upon which it will treat.

The First Part of Duchenne’s work is devoted to METHODOLOGY, AND IS COMPLETE IN ITSELF.

The admirable selection by Dr. Poore from Duchenne’s Clinical Works (published by the New Sydenham Society) renders unnecessary any further publication in extenso of Duchenne’s most voluminous treatise.

“Duchenne’s great work has for years held its place as the most complete on the subject of which it treats, and Dr. Tibbits, by presenting us with an English version of the forthcoming Third Edition, has earned the gratitude of the profession in this country.

“... The reader will find himself so thoroughly instructed in the principles underlying the medical employment of electricity, as well as in all the methods of applying it, that the work can hardly fail largely to increase the use of this powerful and often valuable agent.... The translation itself is very creditable, and reads with almost as much smoothness as original English composition, while the experience of the translator in the Electrical Room of the National Hospital gives great value to his notes and additions. We are happy to congratulate him upon having so far accomplished an undertaking of much utility.”—The Lancet.

“We have to congratulate Dr. Tibbits upon his successful labours thus far. This instalment promises that the results of the best subsequent work will be incorporated into Duchenne’s own treatise with so much judgment and adequacy as to make this Edition an independent standard.... The tentative and accurate spirit of the master has found its kin in the spirit of his follower, and we see little in the work of either open to cavil or correction.”—British and Foreign Medico-Chirurgical Review.

A HANDBOOK
OF
MEDICAL & SURGICAL ELECTRICITY

By HERBERT TIBBITS, M.D., Etc.

CONTENTS.

Opinions of the Medical Press.

“This work fills up a hiatus in the literature of medical electricity. It purposes to teach (to use the words of the preface) ‘the busy practitioner not only when to use electricity, but in explicit and full detail how;’ and in ‘moderate bulk to contain only what it is essential to master.’ Dr. Tibbits’ object has been to give the results of the best work, and to this end he has availed himself freely of the large experience of the Electrical Room of the National Hospital for the Paralysed and Epileptic.

“The work is what it professes to be, and is a handbook in the best sense of the work. The book, indeed, answers thoroughly to the author’s description: that he has ‘throughout endeavoured to keep constantly in view the practitioner rather than the theorist,’ especially in points of detail which are of importance in order to secure the successful application of electricity, and to insure (a not insignificant matter in this respect) the comfort of the patient.”—The Lancet.

“There is not a word of exaggeration, or of fanciful hypothesis in the book, and, above all, there is not the least suggestion that there is after all a mystery behind, and that the reader would do well to come to an expert for advice. On the contrary, everything is made so clear that any practitioner, whether he previously knew anything of electricity or not, may from this book at once begin the practical use of it, and if there are any lingering doubts in the minds of some ultra-conservative persons as to the practical value of electrical treatment, this book should dispel them.... the busiest practitioner can, without difficulty, learn how to effect a large amount of good which he was previously quite unable even to attempt.”—The Practitioner.

“As Medical Superintendent of the National Hospital for the Paralysed and Epileptic, as well as through private practice. Dr. Tibbits has had ample opportunities of studying the application of electricity to medicine, and in the volume under notice, which aims principally at giving full and explicit details within convenient limits, how to use electricity, we are bound to say this object is fairly carried out.”—The Dublin Journal of Medical Science.

“The exact value of electricity as a therapeutic agent is imperfectly understood. That it is of great value in some cases as a means of improving nutrition, relieving pain, and exercising disused muscles, is undoubted, but still its exact value in all cases remains to be settled, and in Dr. Tibbits’ book we find a guide which will, at all events, help us to a solution of some of our difficulties.—The Medical Times and Gazette.

“Dr. Tibbits, who is known as an authority upon electricity, has written a concise book upon this subject for the general practitioner, embracing only the valuable part of the existing knowledge. The work is written in a condensed style, and is well adapted for the practitioner who does not make a specialty of electrical treatment.”—The New York Medical Journal.

DIRECTIONS FOR USING THE
HAMMOND
Wall Cabinet

MANUFACTURED BY
THE WAITE & BARTLETT MAN’F’G CO.,
143 East 23d Street, New York.

TO USE THE GALVANIC CURRENT.

To use the galvanic current place the ends of the conducting cords in the two binding posts marked 13-13. Place the socket of current selector (20) on the pin marked O, and turn the lever of selector on pin No. 1, or on any number, according to the number of cells desired; at the same time see that all the switch levers are on their blank buttons, except the one at left of current selector, which should be on its left-hand button marked Constant.

If it is desired to use cells from any other part of the series, place the socket on the pin from which it is desired to begin, and having previously moved the lever ahead of this pin move it along until the desired number of cells intervenes between socket and lever. The number of cells in circuit when the socket is not on O, but on a pin with a number, is the difference between the number of the pin and number on which the lever rests, for instance, if socket is on pin 12 and lever on pin 22, then 10 cells are being used, the starting point being 12 cells from any part of the series may thus be brought into the circuit. If socket be placed on pin 39 and lever on pin 40 then the 40th cell would be in use only.

Always keep the socket on the lowest number and the lever on the highest, as putting socket ahead of lever would reverse the current.

Should, through any accident, a cell become disconnected or run down, or should it get out of order from any cause, it is only necessary to short-circuit the cells and throw the milli-ampere-meter in circuit by adjusting the switch 10. By placing the socket on the pin marked O and selecting cell after cell with the lever, the defective cell is easily found by the milli-ampere-meter failing to deflect when the pin corresponding to the defect is reached.

TO OBTAIN THE INTERRUPTED GALVANIC CURRENT.

To obtain the interrupted galvanic current, move the switch at left of selector on to button marked interrupted, then turn the switch just above the vibrator on to its button marked 11, by adjusting the screws at 14 and 15 the proper degree of vibration will be obtained. It is necessary that the point of the screws at 15 should touch the plate with every vibration as the current passes through at this point and unless it touches, connections would not be made.

TO MEASURE THE RESISTANCE OF THE PATIENT.

To measure the resistance of the patient turn the lever at the left of selector on to the button 8 marked milli-ampere-meter and wire rheostat. Supposing him to have the electrodes in his hands and a current from 30 cells registers 8 milli-amperes; without changing any other conditions, throw the upper left-hand lever 10 on button marked rheostat and milli-ampere-meter only. The patient will now be thrown out and the needle will fly around as far as it can go.

Begin by throwing in resistance, which is done by manipulating the top row of levers, until the needle which will have retraced its course rests directly over the division marked 8 milli-amperes or whatever may have been the previously recorded amount. The numbers on uncovered buttons added together will be the resistance of the patient. The known resistance having taken the place of the patient.

The upper left-hand lever should at all times except for purposes of measuring the resistance of a patient, be kept on its blank button, or the battery will be short circuited and injured.

THE POLE CHANGER.

The pole changing lever above the two posts marked 13-13, when pressed between the two right-hand springs makes the right-hand binding post positive, and when pressed between the two left-hand springs the left-hand post becomes positive and the right negative.

GRAPHITE RHEOSTAT.

When the left-hand lever is placed on button 9 it throws the graphite rheostat (16) into circuit. To use the rheostat first draw up the rod (17). By slowly pressing the rod down through the graphite it gradually lessens the resistance thereby increasing the current without shock to the patient. With this rheostat you can place any number of cells in the circuit.

THE DE WATTEVILLE SWITCH.

The de Watteville switch is placed directly above the pole changer is used for obtaining either the galvanic or the faradic current separately or the two combined. When the double lever rests on figure 1 and 3 the galvanic alone can be used; can when on 3 and 5 the faradic can be alone used and when on 2 and 4 the two currents are combined and used without changing the conducting cords.

THE FARADIC APPARATUS.

The Faradic apparatus of this cabinet combines a fast and slow interrupter also a single contact key. The style of coil used is the Du Bois-Raymond. To use Primary coil, place the two tips on ends of conducting cords into the two binding posts in front of the coil, the others being connected with any desired electrodes. The strength is increased by drawing the coil to the Right, first placing switch at right end of coil on button marked P.

To use the secondary coil remove the tips of cords from primary posts; then place the ends of cords in the two binding posts 13-13 and place switch on right end of coil on button marked S. To increase the strength of secondary, push coil to the Left gradually, which is just Opposite to what is done in case of primary current.

THE USE OF THE INTERRUPTER.

To use the rapid interrupter which works against the end of core it is only necessary to adjust the screw F, and any degree of vibration may be obtained. The same may be said of the slow interrupter which is adjusted by the screw D, but it is further controlled by the sliding weight at E. By sliding the weight up and down the interruptions are varied from very slow to rapid.

The higher the weight the slower the interruptions and vice-versa. At button G, is the “single contact” used in obtaining single impulse contractions.

The different interrupters may be placed in circuit by a switch on the base of the Cabinet which works over a series of buttons marked S, F and C which put in operation the slow, fast or single contact interrupters, as desired.

DIRECTIONS FOR CONNECTING CELLS.

Fill the cells according to the directions on the cell label, and connect the wires of the cable to the cells, as shown in the cut; No. O being attached to zinc of the first cell, No. 1 to the carbon of the first cell, while at the same time the carbon of the first cell connected to the zinc of the second cell by strip from the carbon of cell, No. 2 wire of the cable to the carbon of the second cell, and so on, the last wire being connected to the carbon of the last cell, as shown by No. 40. The two wires marked faradic should be connected as shown, the four cells being placed in two rows of two each, the zincs and carbons being connected together as shown in diagram.
