This is a work by a physician of reputation on the hygiene of woman, designed for popular use, and introducing a variety of topics not generally discussed outside of regular scientific medical works. Dr. Napheys writes with dignity and earnestness, and there is not a chapter in his book that may not be read by persons of both sexes. Of course such a work as this is intended for men and women of mature years, and it is not suitable to be left lying about for the gratification of idle curiosity. The author has been careful to write nothing that can possibly give offence, and he conveys much sound instruction that, if heeded by those to whom it is particularly addressed, will save much suffering. * * * * * FROM THE INDEPENDENT, NEW YORK, NOV. 11, 1869. It required a brave but sensitively pure man to provide for the want which existed for some reliable medical instruction upon points which every woman and every married man ought to know, and few do. Dr. Napheys we do not know personally. But his book is at once brave and pure. It is written in such a spirit that she who really desires to learn the truths of which she cannot with justice to herself or others be ignorant, may do so without being shocked; while he who hopes to stimulate a vicious imagination by its perusal will turn from its pages disappointed away. * * * * * FROM REV. HENRY CLAY TRUMBULL, Secretary of New England Department of Missions of the American Sunday-school Union. HARTFORD, CT., Oct. 1869. GEO. H. NAPHEYS, M.D.-- _My Dear Sir_: Understanding, from my long acquaintance with you, your thoroughness of mental culture, your delicacy of sentiment, and your sound good sense, I was prepared to approve heartily the tone and style of your new work, "The Physical Life of Woman," when its advance sheets were first placed in my hands. A close examination of it convinces me that it is a book which can be read by every woman to her instruction and advantage. Its manner is unexceptionable. Its style is remarkably simple. Its substance evidences your professional knowledge and your extensive study. I believe it needs only to be brought to notice to commend itself widely. I think you have done an excellent work in its preparation. Sincerely your friend, H. CLAY TRUMBULL. * * * * * FROM THE REV. W. H. H. MURRAY, Pastor of the Park Street Church, Boston, Mass. DEC. 2, 1871. It is with sincere gratitude to the author that I give my endorsement to the book entitled "The Physical Life of Woman." Never was such a work more needed anywhere, or in any age, than it is in America at this time. I should rejoice at its introduction among the people until every wife and mother in the country and the world had a copy in her possession. In it the author has indeed given needed instruction and warning. He deserves the thanks of every Christian and well-wisher of the race. W. H. H. MURRAY.
