The unremitting demand made by an indulgent and appreciative public for a printed edition of the lectures delivered by me in my professional capacity, has furnished the motive for the publication of the present edition, comprising the three most popular lectures of my usual course, to mixed audiences. The work has been prepared for the press hurriedly, while under the strain of enormous professional and personal r esponsibilities, and during the busiest season of a professional practice, which already imposes the burden of fifteen hours per day of incessant labor, which may account for any inaccuracies, typographical or otherwise, which may appear. My lectures on Sexual and Creative Science, delivered to the sexes separately, are now in course of preparation, and will be given to the public in similar form as soon as practicable.
