A man finds satisfaction, when he visits a whorehouse, in the following strange manner: He has a porcelain ring, similar to those used in hanging curtains, which he puts over the head of his penis. Two cords are attached to this ring, which are drawn backward between his legs and attached to the foot of the bed. He then tells the woman to beat him unmercifully upon the buttocks, and cry "whoa1' to him, constantly, as a person would to an unruly horse. The more the woman whips him on to pull, with shouts and blows, the greater his sexual excitement becomes. Erection occurs, and with increasing erection the penis is more and more tightly compressed by the ring, until, finally, ejaculation takes place, with exceedingly lustful feelings." 1

Only by the wildest flight of fancy, certainly, could the slang term, "riding a woman," be applied to such a procedure; but, just as in sadism men excite their lust by maltreating women, or girls, or males, when the actor is homosexual, so in masochism the same sexual stimulation is sought in endurance of similar abuse as in the above case.

With this definition of the terms, masochism and sadism, wdiich makes the conditions, I think, fairly clear, and in illustration of which numberless cases might readily be adduced, I shall pass to the consideration of a far commoner sexual anomaly.
