Sexually considered, civilized man is more beastial than the brutes. He does not respect the person of his gestant wife, and this disregard of natural law is the most potent failure in the curtailment of natural increase. Certain physiological facts indicate that woman is destitute of desire. Carpenter, the great English scientist, is quoted in support of this proposition, and a "female lecturer of distinction" (name not given) to establish the theory that the chief cause of marital unhappiness and the ill health of wives is the sexual inhumanity of husbands--such inhumanity being quite as common among the better as among the uncultured. The foregoing is as delicately as I can state propositions of such far-reaching importance, and which neither Dr. Maxwell nor the "female lecturer of distinction" treat in a manner at all "mealy-mouthed." Even after exhausting my stock of euphemisms the recital appears risque enough to alarm more than one lady reader, and I am tempted to turn back; but courage, good soul! there's nobody looking, and if we must live it is important that we learn. "The proper study of mankind is man;" and we can obtain no true idea of the animal if we view him only in holiday attire. As despite all "progress of science," incubators and other labor-saving machinery, people still persist in entering the world in the primogenial way, the relation of the sexes is of quite immeasurable importance, and knowledge thereof should not be monopolized by the narrow circle who read medical magazines. It is well that we come occasionally out of the cloud-realm of sentiment and discuss the relations of man and woman from the standpoint of practical common sense. I am aware that the views expressed by Dr. Maxwell are entertained by some very able medical men; but they violate the public understanding, and, as usual, the people are right and the specialists are wrong. We do not find desire, as here understood, in plants and the lowest development of animal life, it being particularly an attribute of the higher biogeny. As the more perfect the animal organism the more acute the sensations of pleasure and pain, it follows that in man, most complex of earthly creatures, is found the most powerful procreative passion. But while this is the necessary correlative of his superior nervo-muscular organization, his better attributes are likewise developed--or differentiated--by the same law of evolution. Desire, though accentuated, is refined and rendered subordinate to his reason, while the brute is the blind slave of instinct. With the desire of the man and the reason of the mollusk, the genus homo would be all that he is painted by Dr. Maxwell. Should man become for one day "more beastial than the brute" his boasted civilization would revert to subter-savagery. Under such conditions human progress, society itself, were impossible. It is by no means true, as Dr. Maxwell asserts, that children are born solely because
