PREFACE
▣
THERE are many large volumes published on the subject of Electro-Medicine and Electro-Surgery which are very valuable for reference to those who are familiar with the principles of this subject; but as far as the writer is aware, there is no book published which explains briefly, in a practical manner, all the essential points, from which the student and practitioner can acquire the knowledge of this comparatively new, but thoroughly rational and scientific method of treatment, which can assist the body in the performance of its physiological functions. On this account, the writer has decided to prepare this work.
Although this work is not a complete treatise on the subject, realizing that a successful electro-therapist must be an expert electrician, as well as a good physician, it was the writer's aim to make as clear as possible the production and the therapeutical application of all the different forms of electricity, and to include all the information which is essential for the successful application in the relief and cure of disease.
Those facts and experiments which are of value only to the research worker, and are not essential in the practice of electro-medicine, electro-surgery and radiology, are not included, as that would make this work too large, complex and impractical.
During several years of study and practice, having become fully acquainted with most of the literature on the subject, which has helped him in gaining the present knowledge and thereby enabled him to prepare this work, the author acknowledges gratefully the value of all the works published
