For many years I have wished that some able pen would place before the community at large the knowledge contained in the following pages. Some of this information has appeared from time to time in such books as "Graham's Lectures on Chastity," "Todd's Students' Manual," and a few popular works of a similar kind, which have been of immense service to the human race in preserving chastity and in reclaiming the unchaste. But all these are now inadequate to the growing demand for more light on these vital topics. It has been too much the custom for everyone, parents included, to shrink from instructing their own children, or those entrusted to their care, on these points; consequently, many young people _solely from their ignorance_ fall into the direst evils of a sexual nature and are thereby much injured and sometimes wholly ruined for life's important duties.
