Now however the individual is changed: his face has lost its color, his limbs are stiff, without motion and as it were paralyzed: the head is painful, the mind is slow and the limbs are incapable of the least effort. The hearing is dull, the sight is deranged, and the external senses impart to the brain only imperfect impressions. The pulsations of the heart are feeble, the pulse is small, the veins are collapsed and the eyelids are livid. The soul is left in a state of languor and sadness and becomes as it were melancholy. This picture although giving the principal points is far from being complete; in order to be perfect it should include that which is not as well as that which is seen. If the simple labor which takes place in the genital organs at puberty, is sufficient to modify materially the functions of nutrition, functions which when deranged give rise to many diseases, what must be in this respect the influence of the venereal act, and a fortiori of venereal excesses. This influence, like that exercised by this act on the nervous system cannot be appreciated at the moment it is produced, for it is not immediately perceptible. An idea of this can be gained only in two modes: one consists in measuring the long intervals which exist between a state of repose and that of action: we then say that if the first can modify to such an extent the texture of these organs, their powers of sensation and of action, how great must be the power of the second. In this manner we reason in this instance. In the other mode an opinion may be formed by remarking the physical alterations and functional disorders which have been the consequence of them. This kind of proof which we shall soon examine will not fail us. We shall then see that the diseases affecting the nervous system, that system which is powerfully disturbed during coition, are not the only ones resulting from venereal excesses. We shall see that all alterations of tissue, every physical disorder, may be caused by them: and thus we shall complete the proof of this fact that the act of venery not only produces that convulsive state which is so powerful while it continues but that it also exercises on all parts of the body an action which is extremely powerful and is also the source of many evils. When we think of the power of the act of venery, and consider that it may be indulged in as often as an individual chooses, and that if the legitimate mode of indulgence, the concurrence of the sexes is denied, the individual may abuse himself; when we reflect we say on all this, we may fearlessly assert that most of the inconveniences and diseases afflicting the human species, arise from venereal excesses.
