From our remarks on the influence exercised by the genital organs on the nervous system, even when simply in a state of excitement or repose, it will not surprise, if we should state, that in this system are seen the affections resulting most frequently from the abuse of these organs. In fact the diseases of motion, sensation or of intelligence, that is of the faculties which are situated in the nervous system, are in fact the most common consequences of masturbation, and of venereal excesses generally. We have already spoken of the gradual diminution in the locomotive powers of the onanist. That of sensation presents very different phenomena, it is exalted as much as the first is diminished. Farther it is admitted that these two faculties are in an inverse ratio to one another. This increase of the susceptibility may take place at any age in consequence of venereal excesses; but it occurs much more readily in young persons, that is at that period of life when the mode of sensation assumes those characters which at a later period more than all the others constitute the temperament. Thus the excessive susceptibility generally presented by onanists, does not belong to those transient symptoms which disappear when the habit ceases: but, on the contrary, it continues, long after the habit has ceased, and its influence is long felt. How many persons of every age complain of being extremely nervous. Some know that this depends upon their own conduct, which they deeply regret. Interrogate them, and many will admit the excesses of their youth. We have rarely neglected to verify this remark and the responses have generally confirmed my suspicions. These individuals are seldom free from disagreeable feelings, from pain and inconvenience of some kind: their symptoms may vary extremely, and change very suddenly, but they are generally or always indisposed one way or another. This can be readily imagined: every thing affects them: cold, heat, dryness, moisture, rain, snow, food, drink, exercise, rest, in fact all these modifying circumstances find in them an organization ready to be acted on. The act of venery, the first source of their nervous susceptibility, subjects them to constant privations. A young man, twenty-two years old, whom we attended a few months since, told me in a depressed manner the constant inconveniences which he experienced from onanism. The following is his narrative, which we shall give here because it presents a faithful picture of the state in which the nervous system exists in most persons who have indulged in onanism.
