experience, especially as there is added that indirect gratification of it which results from the preference being witnessed by others.  Further, the allied emotion of self-esteem comes into play.  To have succeeded in gaining such attachment from and sway over another is a proof of power which cannot fail to agreeably excite amour propre.  Yet again, the proprietary feeling has its share in the general activity.  There is the pleasure of possession, the two belonging to each other.  Once more, the relation allows of an extended liberty of action.  Toward each other a strained behavior is requisite.  Around each there is a suitable boundary that may not be crossed; an individuality on which none may trespass.  But in this case the barriers are thrown down, and the love of unrestrained activity is gratified.  Finally, there is an exaltation of sympathies, egotistic pleasures of all kinds are doubled by another’s sympathetic participation, and the pleasures of another are added to the egotistic pleasures.  Thus around the physical feeling forming the nucleus of the whole, are gathered the feelings produced by personal beauty that constitutes simple attachments, of self-esteem, of property, of love of freedom, of sympathy.  These, all greatly exalted and severally tending to reflect their excitements on one another, unite to form the mental state we call love.  And as each of them is comprehensive of multidinous states of consciousness, we may say that this passion fans into immense aggregate most of the elementary excitations of which we are capable; and that hence results its irresistible power.”

What Constitutes a Suitable Husband.—­ It is desirable that the husband shall be a few years older than the wife.  Man is later in coming to maturity, and also retains his sexual powers considerably longer than woman; so that for these functions to cease about the same time, the wife must be younger than the husband.  A difference of from two to five years is best; if the parties are young, it is not essential that the husband should be much the wife’s senior, as it is later in life.  The husband may be ten years older, but a greater disparity of age than this is rarely compatible with congeniality of tastes and dispositions, so essential to a happy married life.  The woman who risks her happiness with a man many years younger than herself violates a precept of nature.

The average stature of the man is about three inches greater than that of the woman, and in the physiologic marriage any great deviation from this should be avoided.

The essentials for a happy marriage may be summed up as follows:  that the parties shall be of suitable age; that they shall be physically well mated and in full sympathy with each other’s views of life, of the same social position, and of equal education.
