Before a young man marries he should always seek advice from a trustworthy source with regard to his conduct as a husband. No satisfactory book is, or perhaps could be, published on this subject; and even if a young man can make up his mind to consult a doctor, it is by no means every doctor who has the needful knowledge on this subject or the best moral outlook. It has been my privilege to help several in this matter, and I am always happy to do this. TO BOYS AND YOUNG MEN. I earnestly warn you against those who, by advertisement in the papers, offer to cure young men who are suffering from weakness of the private parts and other ills which impurity entails. Many such advertisers are little better than rogues, who are out to make money by trading on the fears of their victims; their "treatment"--quite apart from a far greater cost than at first appears--often does more harm than good. In every case in which disease or weakness exists, or is suspected, a reliable medical man should be at once consulted. If this is done, a cure may generally be looked for. Do not write to me; this is a doctor's business, not mine.
