As to just when it is best to put this information into the hands of young married people, my experience has varied with the personality of the parties concerned.  In some cases I have put the copy into their hands some time before their marriage; in others, not till some time thereafter; but, as a rule, I have got the best results by putting the manuscript into their hands just at the time of their marriage, and in most of these cases the greatest success has come from their reading it together during their honeymoon.  However, this is a matter on which I do not care to advise, and regarding which each practitioner must act to the best of his own judgment.

Once more:  Because it is not safe to assume that young married people are already possessed of the details of the essential knowledge which they ought to possess, and because such details are the very heart of the whole matter, I have made these details as simple and explicit as possible, more so than might seem necessary to the professional reader.  But my experience has proven that I was wise in this regard, as these very details have saved the day in more than one case, as the parties who have reported to me, after having read what I have written, have frequently testified.  Sometimes a bride and groom would keep the copy for a few days only, giving it but a single reading; but, as a rule, they have been anxious to retain it for some time, and to read it again and again, especially some parts of it, till they were well posted on all that it contains.  I found, too, that those who had received help from the reading of the manuscript were glad to tell others of their friends of the benefits they had received, and that thus there was a constantly widening circle.

Of course, not all young married people are capable of reading this book with profit to themselves or anyone else; but many of them are, and these ought to have the privilege of doing so.  Your own good sense and experience will determine who these latter are, and these you can favor as they deserve.  It is because of this situation that this book can only be used professionally that it needs the guiding hand of an expert physician to insure its reaching only those who can be benefited by its reading.

As to the other class of readers, those who have not got on well in the marriage relation (and we all know that the name of these is legion) my experience in getting to them what I have written has been quite varied; but, on the whole, the results have been good—­many times they have been most excellent.  Of course, it is harder to correct errors than to prevent them; but as most of the errors I have had to deal with among this class of patients have been made through ignorance rather than otherwise, I have found that the establishment of knowledge in the premises has generally brought relief where before was only suffering and woe.
