PREFACE TO SECOND EDITION.

The demand for a second edition of this hook in little more than a week after the publication of the first, indicates the interest which the public take in the relation of Sex to Education, and justi­fies the author in appealing to physiology and pathology for light upon the vexed question of the appropriate education of girls. Excepting a few verbal alterations, and the correction of a few typographical errors, there is no difference be­tween this edition and the first. The author would have been glad to add to this edition a sec­tion upon the relation of sex to womens work in life, after their technical education is completed, but has not had time to do so.
