Electro Physiology and Electro-Therapeutics; showing the best methods for the Medical Uses of Electricity. By Alfred C. Garratt, M. D. Boston: Ticknor & Fields.

This work is intended for the 'profession, and to many it opens a new field for labor and investigation; one in which heretofore they have never trod. Although this subject has but recently engrossed the whole attention of many of our best and ablest men; although the science of its application as a remedial agent is still in its infancy, yet its power is known and felt-its results acknowledged and to be seen in almost every portion of our country.

The work before us is one which we feel we can commend to our friends with pleasure, for by its study they will be enabled to obtain both knowledge and profit.

Dr. Garratt is not a fanatic. He treats his subject calmly, deliberately and scientifically. His language is chaste, clegant and well chosen. He has endeavored to be deep but clear, profound but intelligent. His work is, indeed-being the only one of the kind in the English language—an honor to him and a credit to his country.

The author gives his opinions and the results of his inves tigations in a candid manner, without any egotistical display or dictatorial manner so common among writers at this day when treating a favorite theory of which it may be they are the only supporters, and thus endeavoring to force their opinions upon the minds of others, and make them proselytes to their particular doctrine. But in this work is given the conclusions arrived at by the writer from certain causes-what he really believes to be facts-and leaves the reader to form his own opinions, to draw his own conclusions, and to decide entirely for himself whether Electricity is or is not a very valuable remedial agent.

"The progress of medical science," of medical science," says Dr. Garratt, "during the past half century, has brought us into new and closer relations with almost all other departments of PHYSICAL SCIENCE, but with none, however, in so intimate and indissoluble a manner as with this of electricity."

"The author, being profoundly convinced of the efficacy

of electric currents as a remedy, capable of producing, often, a radical cure, especially in nervous affections, bespeaks a generous and impartial reception by our American medical world, of what is already achieved for and in electro-physiology and electro-therapeutics; i. e., as to what relates, in a scientific sense, to the medical uses of Electricity.

"A systematic work on the medical and surgical uses of Electricity, containing clear and practical directions as to where, when, and "how," to employ Electricity as a remedy, (embracing at the same time the condensed scope of those natural, accidental, as well as artificial electric influences that affect life and health,) has long been greatly needed; and of late flatteringly requested of the author, by many distinguished members of the most venerable medical association in America, to fill, in some degree, this deficiency in our medical literature. True, we have had published in this country some small, yet valued treatises on this subject -one by Dr. Golding Bird; another by Dr. W. F. Channing. But these pioneer works were rather "evidence and argument," to exhibit and convince of what has, might, and would be accomplished by the medical uses of Electricity, rather than giving any philosophic and rational expose of the methods of doing it. Therefore what has been done by the agency of Electricity, in the way of remarkable cures, empirically or otherwise, if the modus operandi is not also clearly given, is purposely excluded from this work. The author has aimed to confine himself to gleaning from the highest practical authorities, and the comparing of these with his own clinical experiences, then classifying and arranging the subject matter, so as to present the whole range of electro-therapeutic practice, on a more systematic and scientific basis.

"And further, the author would only say, that he is most deeply impressed that too much stress can hardly be laid on the value of the culturing influences of this study of natural science, whether for leading on to a more rational and intelligent view of medicine, or as cultivating the powers of general observation, training the mind, as it does, to

more precise discrimination and orderly arrangement of ideas, and that without hasty or foregone conclusions,enriching the mind with general and individual facts of daily application, or ennobling it by the knowledge of those great laws and harmonies which make all nature eloquent with the wisdom and goodness of our Creator."

This work should be in the hands of every student of medicine, of every practitioner in the land; and no medical Library should be considered complete without it. If the profession is true to themselves, true to their interests, and the interests of their patients, several editions will have to be issued to supply the demand; for it is the bounden duty of every physician to examine and to study every remedial agent which may come to his knowledge, and know how, when and where to make a proper use of it in order to relieve suffering humanity.

THE TWO BEST DOCTORS.-For all minor aches and ails, Dr. Letalone is the most uniformly and happily successful physician I ever knew; but in the severer forms of disease it is always wisest, safest and best to seek promptly the advice of an educated practitioner; and a fortunate thing would it be for humanity, if not an atom or a drop of physic were ever taken, unless specially prescribed by those who had the advantage of a thorough medical education.—Hall's Journal of Health.

THE NEW FRENCH CODEX.-The Pharmaceutical Society of Paris, is at present preparing the materials for the drawing up of a new codex or pharmacopoeia, with a view to facilitate the work of the committee shortly to be appointed by government, for the publication of that work.

Since the establishment of the charitable Eye and Ear Infirmary in Chicago two years since, two hundred and ninety-two patients have been under treatment.

ANESTHETIC EFFECTS OF BISULPHIDE OF CARBON."Dr. Wm. H. Uhler, of the Falls of Schuylkill, at a recent meeting of the Academy of Natural Sciences, mentioned that he had a short time before accidently inhaled the vapor of the bisulphide of carbon, which had produced complete anæsthesia. He was removed from the laboratory by the workmen in a completely insensible condition. He revived in a short time suddenly and completely, and he did not subsequently experience any nausea or the least unpleasant symptoms. Whilst in a state of anesthesia, his visions were of the most pleasant and agreeable character." -Med. News.

ENDURANCE OF THE HORSE.-Some cruel experiments have lately been made at Paris to test the endurance of horses. It appears a horse will live on water alone five and twenty days, seventeen days without eating or drinkink, only five days if fed but unwatered, ten days if fed and insufficiently watered. A horse kept without water for three days, drank 104 pounds in three minutes.

Phosphornecrosis is becoming so prevalent among those engaged in making lucifer matches in Paris, that the government has consulted the Academy of Medicine as to means for preventing this terrible malady. The Academy simply recommends, that as a preventive, matches should be made of pure amorphous phosphorous, or without phosphorous at all, the white phosphorous being altogether prohibited.

FROXINUS EXCELSIOR (Common Ash.)-The tincture of ash-bark has been used in gout, rheumatism and ague. Its value in gout has been tested for half a century. As long ago as 1712, it was used in the place of cinchona bark, but in somewhat larger doses.
