Two New Books by Dr. Winfield Scott Hall

Dr. Hall's "SEXUAL KNOWLEDGE" is recognized as the only work of the kind written by an accepted authority and more satisfactorily covers the important subject completely than any other book. Appeals have been made to him to prepare books that treated the subject separately from the standpoint of the boy or girl by those who prefer placing books in the hands of young people treating the side of the question that concerns them individually. These new books have been prepared to meet this demand.
