PREFACE.

THE need of a simple guide for the general practitioner has prompted the production of the following pages. I have endeavored to make them as practical as possible by avoiding as many of the confusing theories, technical terms, and unproved statements, as I was able. In presenting this little book to the profession, I intend to indorse electricity only as a very valuable remedy in certain diseases, not as a specific for every human ill, mental and physical. As a therapeutical means in nearly all forms of Nervous disease, Electricity is invaluable.

I have not mentioned several new modes of application, only because I think they have not been sufficiently or generally tested. My book is the compilation of well-tried measures and reported cases.

I do not enter into the detailed description of the various diseases I allude to, as there are many elaborate and concise works upon this subject, that may be consulted by the reader.

I am indebted to Drs. Frankel, Piffard, Murray, Fisher, Rankin, and others, for their kindness in furnishing me with reports of cases and other data.
