any effect. The absurd pretensions of galvanic baths for the extraction of mercury from the system will be remembered by most of our citizens, and the shocking practice of others is not forgotten.
It was therefore earnestly desired by medical practitioners who themselves were not by education competent to manage electric and galvanic machinery, that some medical man of good standing, who had made a special study of this subject, should undertake the treatment of diseases requiring the use of electricity. Dr. Garratt was induced to undertake this important duty, and he has prepared a work on this practice which embraces all that has appeared in the writings of others, both in this country and Europe, while he has, from his own researches and rich experience, added much new matter of great practical value. Among his original contributions we note,--
1st. A definite, systematic method for the application of Galvanic and Faradaic currents of electricity to the human organism, for curing or aiding in the cure of given classes of diseases. (See pages 475, 479, and 669 to 706; also Chap. 5, p. 280.)
2d. Improvements in the methods of applying electricity, as stated on pages 293 to 296, and 300, 329, and 332, which we have not room to copy.
3d. He has introduced the term Faradaic current to represent the induced current, first discovered by Professor Henry, and so much extended in application by Faraday.
4th. The determination of several definite points in sentient and mixed nerves, often the seats of neuralgic pain,--thus correcting Dr. Valleix's painful points.
5th. The treatment of uterine, and some other female disorders, by means of the induced galvanic current (pages 612 to 621).
A careful examination of this book shows it to contain a very full _résumé_ of the best which have been written on the subjects embraced under the medical applications of electricity in its various modes of development, and a careful analysis of the doctrines of others;
