_Dear Sir_: I have carefully read your work entitled "The Physical Life of Woman," and, as the result, I must candidly say that I believe the information it contains is well calculated to lessen suffering and greatly benefit the human race. I know there are some falsely fastidious persons who would object to any work of the kind, but "to the pure all things are pure." You have done your part fearlessly and well, and in a popular manner, and I trust that your work may be productive of all the good you design by its publication. Very faithfully, GEO. ALEX. CROOKE. * * * * * OPINION OF LLOYD P. SMITH, Esq. Librarian Philadelphia Library. LIBRARY CO. OF PHILADELPHIA, FIFTH ST. BEL. CHESTNUT, PHILADELPHIA, Sept. 1869. It is an open question whether books de _secretis mulierum_ should be written for the general public; but there is no doubt that, when they are written, it should be done by the regular faculty, and not by ignorant quacks. Dr. Napheys' "Physical Life of Woman" shows not only the scientific attainments of the author, but also a wide range of miscellaneous reading. The delicate subjects treated of are handled with a seriousness and earnestness becoming their importance, and the author's views are expressed in excellent English. LLOYD P. SMITH. * * * * * OPINION OF S. W. BUTLER, M.D. Editor of the Philadelphia "Medical and Surgical Reporter." I have carefully examined "The Physical Life of Woman," and find it a work at once thoroughly representing modern science, and eminently adapted for family instruction. It is well suited to female readers, to whom it is especially addressed both in the matter it contains and in the delicacy with which points relating to their physiological life are mentioned. S. W. BUTLER. * * * * * EXTRACT FROM LETTER RECEIVED FROM JOHN H. GRISCOM, M.D. NEW YORK, Sept. 1869. DR NAPHEYS-- _My Dear Sir_: The "Physical Life of Woman" is a very scientific and intellectually written work, and contains almost all the physiological and sanitary facts and directions needed for the preservation of the health and longevity of the maiden, wife, and mother. It must prove attractive and useful for any lady who reads it. Your sincere friend, JOHN H. GRISCOM. * * * * * FROM THE NATIONAL BAPTIST, PHILA., DEC. 30, 1869
