We have already stated, that there is a reciprocity of action between different organs: if there be one which exercises a marked influence on the other, the latter will in turn affect the former. This may be proved by the cerebellum, which sometimes becomes diseased after abuses of the genital organs, and sometimes communicates to these organs the over-excitement which is accidentally seated in it: the spinal marrow, also, confirms the fact.

Willis, who, before Gall, had sought to localize in the nervous centres the faculty of reproduction, had designated the spinal marrow as the organ of this faculty. Numerous observations, and many experiments, have lately given some credit to this opinion. Segalas, who produced erections of the penis in Guinea pigs, by introducing a stylet into the cerebellum, caused ejaculations by pushing this instrument into the spinal column, near the lumbar region. Serres repeated this last experiment, and the result was similar: he therefore concluded that the lower part of the spinal marrow acts on the secretory and excreting seminal apparatus, as the cerebellum acts on the genital sense. We shall see, also, that this opinion is too positive, as the lesions of the medulla exert a marked action on erection of the penis and the venereal sense, besides the influence on the ejaculation attributed to it by Serres.

A case, reported by Lenhossek, seems to establish, that compression and atrophy of the spinal marrow may oppose the development of the genital organs. This patient was twenty-four years old: he was thin, wasted, and his height was that of an individual twelve years of age. Neither his face nor genital system presented the characters of puberty. This individual died suddenly; and it was found, that in consequence of a malformation of the first and second cervical vertebræ, the diameter of the occipital foramen was contracted one half. The medulla oblongata had been compressed in this part, and its development was impeded. Might not the singular disease, observed by Larrey in Egypt, and afterward in Paris, be referred to an affection of the spinal marrow? Here the testicles gradually wasted; the patient lost the power of feeling venereal sensations, and also that of erections; the lower extremities shrunk away, and tottered; the face was discolored; the digestive powers and intellectual faculties were deranged. Does not this coincidence, of a considerable weakening of the lower extremities and the wasting of the testicles, indicate that this latter has been the consequence of an affection of the spinal marrow?

Dupuytren long since established the fact, that priapism was caused by a lesion of this organ. Numerous instances of this are found in Olivier’s work on the spinal marrow: they prove, that every part of the medulla, but particularly the cervical portion, when injured, may cause an erection of the penis. Potain, Renauldin, and Hedelhofer, have stated similar facts. This last author saw a man who fell upon his sacrum, and instantly had an emission. Professor Fages was in the habit of mentioning the following case in his lectures:—“An aid-de-camp of General Dumourier was affected with complete paralysis of the lower extremities, in consequence of a fall from his horse. This paralysis was attended with a great degree of priapism, which encumbered him very much, and caused retentions of urine, which were treated by the most active refrigerants. Going through Montpelier, on his way to Balaruc, he rested several days at the military hospital, where it became expedient to sound him. In order to do this, it was necessary to uncover the whole body, to expose it for some time to the cold air, and to apply to it cold water; and, even then, the sound had to be used promptly, otherwise erections would soon have supervened, merely by touching the penis, and by the presence of the sound in the urethra. The baths of Balaruc almost cured the paralysis; and as motion returned to the lower extremities, the priapism disappeared.”

Do not these facts show that the spinal marrow has a marked influence on the genital organs. We have already mentioned the opinion of Sainte Marie, who regards involuntary pollutions as sometimes the cause and sometimes the result of affections of the spinal marrow. May not an original or accidental state of this organ be, in some subjects, the indirect cause of venereal excesses? Remark the influence of a recumbent position, in producing voluptuous dreams and emissions of semen. Does not this singular effect depend on the heat of the spinal marrow caused by this position? This is possible, particularly if you consider the advantages derived in involuntary pollution, priapism, and satyriasis, from douches of cold water along the vertebral column, particularly on the lumbar and sacral regions, and also from the application of ice to these parts. Sainte Marie has sometimes arrested the spasm of the genital organs by frictions on the sacrum with bladders full of ice. We think, then, there are cases where these remedies may be used successfully to combat the habit of masturbation. Narcotic frictions and endermic applications may be made along the vertebral column, as we have said, when speaking of the cerebellum. In vigorous patients, leeches and cups may be applied to the loins. We will not allude here to the remedy recommended by many old authors, of a sheet of lead to the kidneys, for this cannot produce the refrigerant effect expected from it.

The organic conditions of venereal desire are confined neither to the cerebellum nor spinal marrow: they may exist, also, in all parts of the genital system, as we shall demonstrate.

A considerable part of this system is formed of a tissue termed the erectile, on account of its power of swelling, hardening, and becoming erected. It constitutes the whole of the cavernous bodies—the glans, which is the loose extremity of these bodies—the spongy part of the urethra—the clitoris—and a considerable portion of the vulva and vagina. The part taken by this tissue in the work of generation, would indicate that it is affected in amatory desires, and that its state must exercise some influence upon them; which is demonstrated by the facts we shall mention.

There is no vice in the human species without its representative in some class of animals. Thus, the inclination to theft, to destroy, &c., are found in some species existing to a great degree. So, too, with luxuriousness. There is a class of apes—the dog-faced—which represent it. It is impossible to form an idea of the lasciviousness of these animals, which is manifested at sight not only of a female of their own class, but at that of a woman: they show by their looks, gesture, and voice, that they are excited. They are extremely jealous at sight of a man. They indulge in coition to great excess; and if this be impossible, they abuse themselves. How does their organization differ from that of other animals?—in the cerebellum?—in the spinal marrow? No: but according to Desmoulins, by the enormous mass of erectile tissue which they have. This tissue abounds not only around the sexual organs, but is found in the haunches and pubis. In the face, it is not confined as in us to the lips, but it covers the face, and there presents a brilliancy of color which exceeds that of the vulva and glans in our species. It should be remembered that the kunocephali do not exhibit this lasciviousness until puberty, when this tissue is developed, and assumes its brilliant colors.

Here, then, are animals, in whom the erectile tissue evidently performs the part attributed by phrenologists exclusively to the cerebellum. Why may not the same thing exist in our species? Are not the penis and clitoris, generally speaking, much larger in those who have a marked propensity for the pleasures of love? Is not their erection the most constant sign of the activity of the venereal sense? Is not the erectile tissue developed at puberty, at the same time with this sense, and does it not collapse in old age? Finally, does not the genital sense exist at its highest degree in the glans—the clitoris—that is, in the organs formed entirely of this tissue?

There is, then, reason to seek the principle of masturbation in this tissue, and to this remedies should be applied. This is done in a vigorous and healthy patient by blood-letting, and by applying leeches or cups around the sexual parts. Lotions and cold applications to these parts, and cold hip-baths, act in the same manner; and as they do not contribute to the exhaustion, they are employed more frequently. Sainte Marie recommends that the genital organs of individuals affected with spermatorrhœa should be covered with bladders of pounded ice, which should be removed as often as it melts. This remedy seems more efficacious and convenient than the application of wet sponges or linens to the parts. It might also be used in those onanists who will consent to it. The same indication is fulfilled by forbidding children to be washed in warm water, and by causing them to use hard cushions to sit on; and likewise, by keeping the pelvis lightly covered, and the clothes large enough to allow the air to circulate freely around the genital organs. The cold injections, in girls, may also be somewhat useful. There is also another remedy which is applicable to parts formed of erectile tissue, and which we shall mention—viz., their removal.
