The first part treats of the peculiar function of the male, describes the period of puberty when this function begins, and gives the rules of health at this time. The author theu passes on to virility, or the period when this function is most vigorous; describing its signs, the causes that hasten, and those which delay the loss of it, the effects which certain dis eases, occupations, and exercises have upon it; the food and drinks which strengthen it, and those which weaken it. The instructions "How it can be prolonged," are especially valuable to middle-aged and elderly men. The sexual passion is analyzed, and two full chapters given on the drugs which stimulate and those which moderate desire.

The second part is on the single or celibate life, and contains matter which every parent, clergyman, and educator should be conversant with. After speaking of the advantages and disadvantages of unmarried life from a medical point of view, the author proceeds to discuss four important questions, chiefly concerning young and unmarried men. These are the solitary vice (self-abuse), spermatorrhoea, secret diseases, and the social evil (prostitution).

In reference to the first of these, the consequences, the prevention, and the cure of the destructive habit of self-abuse are detailed fully, and in plain language.

Spermatorrhoea is treated of under the headings "What brings it about ?" " How to prevent it," and "How to cure it."

The two most frequent secret diseases are described briefly and clearly; their effects on a man and on his children explained; means of prevention and treatment are mentioned, and the very important question answered, How soon ought a man to marry, who has been diseased ?"

The chapter on prostitution is written with especial reference to the United States; the number of fallen women in the different cities and the classes into which they are divided, are described. The questions where they come from, how they live, and what becomes of them, are answered, and the various plans for their reform are discussed.

The third part of the book is on the Married Life. Every man, either married or contemplating marriage, will find here information which he would not be without for very many times the price of the book. The part opens with advice in reference to the age best for marriage, the choice of a wife, the dangers (physical) of long engagements, etc A section is given to the consummation of marriage, and the obstacles to it, both on the part of the female and the male. The latter the author divides into four: First, Lethargy of the organs; second, Debility; third, Impotence; and fourth, Sterility. He explains the nature and causes of each of these conditions, and adds the special treatment which they require.

The next chapter is on the marital relations. The dangers of excess are pointed out, and the rules of moderation laid down.

The nature of conception is then explained, and an ex tremely interesting chapter given on the avoidance and limitation of offspring. Not less interesting to married people are his full and explicit directions how to have malt or female children at will. The rules given are strictly scientific, and are also applicable to domestic animals, stock horses, etc., and will therefore doubly interest most people.

In the chapter on inheritance the author tells what parents can do to avoid having diseased, deformed, and weak-minded children, and to have those which are hand, some, healthy, and intelligent.

The subject of nervous disorders originating in the male generative system is one of intense interest, and is treated in a practical manner.

The chapter entitled " medical views on popular medical Instruction" shows the awakening interest in the profession on the importance of this theme, and the danger to the public of leaving it in the hands of ignorant and unscrupulous writers.

The article on the relation of the sexes in early life is one that should be read by every parent and teacher.

The discussion on the relation of sex to disease will be found of interest.

A general summary of the moral relations of the sexes, as set forth in the Bible and by theological writers, closes the work.

The book will be found thoroughly practical. It is intended for self-help, and contains a number of valuable receipts.
