PREFACE TO THE SECOND EDITION.


THE author takes this opportunity to thank the medical profession and the laity for the very cordial reception which has been tendered the first edition of this small volume.

The necessity for the use of technical expressions in a book written expressly for the laity must always be a matter of regret. And only those who have attempted to write a similar work can fully appreciate the truth of Herbert Spencer's remark, that "Nothing is so difficult as to write an elementary book on scientific subjects."

The author has added to this edition a section on "The Hygiene of Puberty," one on "Hemorrhage at the Menopause a Significant Symptom of Cancer," and one on "The Hygiene of the Menopause."
