This work discusses, in a familiar manner, all subjects connected with physical education and self-management. It treats on the connection of LIGHT, AIR, TEMPERATURE, CLEANLINESS, EXERCISE, SLEEP, FOOD, DRINK, CLIMATE, the PASSIONS, AFFECTIONS, &c., with HEALTH, HAPPINESS and LONGEVITY. The editor takes the ground that a proper understanding of the constitutional laws of the human body, and of all its organs and functions, and a strict obedience thereto, are indispensable to the highest perfection and happiness—present and future—of every living human being. He deems this knowledge more and more indispensable in proportion to the progress of civilization and refinement. The work is pledged to support no system nor set of principles, any farther than that system and those principles can be proved to be based on the laws of Physiology, and revealed truth, and on human experience; and consequently its pages are always open to fair and temperate discussion. The work has recently been warmly approved of by GEORGE COMBE, (author of the “Constitution of Man,”) as well as a large number of distinguished men of this country, among whom are the following: Dr. John C. Warren, Dr. S. B. Woodward, Rev. Dr. Humphrey, Rev. S. R. Hall, Rev. Hubbard Winslow, Rev. R. Anderson, Rev. Baron Stow, Rev. B. B. Wisner, R. H. Gillet, Esq., Rev. Wm. Hague, Roberts Vaux, Esq., Dr. John M. Keagy, Dr. R. D. Mussey, Prof. E. A. Andrews, Rev. L. F. Clark, Rev. M. M. Carll, Rev. Dr. Fay, Dr. Sylvester Graham. These recommendations are similar to the following, received from Dr. WARREN: “The Library of Health, is, in my opinion, an excellent publication. It seems to be well adapted to aid in the great reform in habits and customs which is now going on in this country and Great Britain; and which, it may be hoped, will extend to other parts of the world. I beg leave to recommend this little work to all who are desirous of promoting their health of body and tranquillity of mind.” Many of the most respectable Journals in the country, have also given their testimony in its favor. The following are a very few of them: Boston Medical and Surgical Journal, Annals of Education, Abbott’s Religious Magazine, Boston Recorder, Christian Register, Christian Watchman, Zion’s Herald, New York Farmer. We feel entire confidence in offering this publication to all who are interested in the improvement which Dr. Alcott is endeavoring to promote. ------- THE YOUNG MAN’S GUIDE. BY DR. ALCOTT.
