_Dear Sir_: I have examined your volume: "The Physical Life of Woman," and desire to thank you for performing a work so long needed, so difficult to perform, and now, at length, so well done by you. Every mother should have this book, nor should she suffer a child to be married without the knowledge which this work contains. Thousands have dragged through miserable lives and many have perished for want of such knowledge. It is to be hoped, too, now that these delicate topics have been so modestly and plainly treated, that your work will supersede the scores of ill-considered and often mischievous treatises addressed "to the married," which too often serve the lusts of men under the pretence of virtue. HENRY WARD BEECHER. * * * * * FROM REV. HORACE BUSHNELL, D.D. HARTFORD, CONN., Sept. 1869. GEO. H. NAPHEYS, M.D.-- _Dear Sir_: I have read a large part of your book with interest. I shrink from expressing any estimate of it as respects its physiological merit, but it seems to be a book well studied, and it is written with much delicacy and a careful respect, at all points, to the great interests of morality. It will certainly be a great help to intelligence on the subject, and ought, therefore, to be correspondingly useful. Very respectfully yours, HORACE BUSHNELL. * * * * * FROM HARVEY L. BYRD, M.D., Professor of Obstetrics in the Medical Department of Washington University of Baltimore, Maryland. BALTIMORE, Sept. 1869. DR. GEO. H. NAPHEYS, Philadelphia-- _Dear Sir_: I have examined with much pleasure and satisfaction your work on "The Physical Life of Woman," and do not hesitate to commend it most warmly to our countrywomen, for whose benefit it is intended. I congratulate you on the felicitous manner in which you have treated so difficult a subject, and would recommend it to the public as supplying a want that has long been felt in this country. _Omne verum utile dictu_, and what can be more proper or more useful than that woman should be made acquainted with the great laws of her being and the duties for which she was created? Very respectfully, your obed't servant, HARVEY L. BYRD. * * * * * EXTRACT FROM LETTER RECEIVED FROM EDWIN M. SNOW, M.D., OF PROVIDENCE, RHODE ISLAND. PROVIDENCE, Sept. 1869. DR. NAPHEYS-- _Dear Sir_: I have examined with much interest the advance sheets of your book, "The Physical Life of Woman:" I am highly pleased with it. The advice given seems to me to be generally correct, and judiciously expressed; and, in my opinion, the wide circulation of the book would be a benefit to the community, Truly yours, EDWIN M. SNOW. * * * * * FROM REV. GEORGE ALEX. CROOKE, D.D., D.C.L. PHILADELPHIA, Sept. 1869. DR. GEO. H. NAPHEYS--
