one, but with no declension of the tumescence, and I was able to repeat this maneuver several times before the full orgasm.  This I later practised in Coitus prolongatus—­giving the partner time to come up.  I had already got into the way of poising the feeling on its climax.  The ejaculator reflex, being habituated to this, seems to set in with its throbs when the maneuver is simulated, though no semen has yet been poured into the bulbous portion for the ejaculators to act upon.  If this play be broken off before the critical spasm—­as in the American ‘Karezza,’ etc.—­there is no perceptible reaction, though an unsatisfied feeling remains.  But when the act proceeds to emission and the poignant undercurrent of feeling sets in that ushers the ejaculation and may only last two to five seconds, it makes all the difference, and constitutional signs appear—­perspiration, etc.  This leads to the question whether the critical sensation specially involves the sympathetic nervous system?  Up to that point the process is under control, but then automatic.

“An observation of practical importance to me at that time was this:  I awoke in the morning after a pollution at night, with an acute headache of a specific kind, and erection.  This had happened before, after pollution, and the erection suggested to me whether ‘a hair of the dog that bit me’ might not prove beneficial.  As the excitation proceeded, the pain in the head was directly drained away, as if I were drawing it out.  Other pain is also relieved for the moment, such as neuralgia, but to return soon with interest.  This, however, was specific and pure benefit.  The next time I got a bad headache of this character, without preceding pollution, I tried the remedy, at about 10 A.M.  The semen was copious and watery, and the relief was marked, but in an hour’s time the headache returned.  I had never repeated the act at short interval, i.e., while the organs were under the influence of a previous act, and now I tried the effect of that.  The second emission was also profuse, but much thicker, and the relief much greater.  In about three hours the headache was, however, again intolerable, and, the connection being now clear, I ventured on a third act, which proved to be the most voluptuous I had so far experienced, the nisus being far more intense.  The semen was copious, but thick and ropy, with lumps as large as small peas that could scarcely be crushed with the finger, and yellow in color and rank in odor.  After that I was perfectly well and kept so. (The urethra was blocked so that I could with difficulty stroke the masses out.) Later I have examined such semen microscopically and found the spermatozoa dead and disintegrating.  My period in my best years—­21 to 48—­was twice a week, the odd number being an inconvenience, and I have since endeavored to avoid accumulations, emptying the receptacles on the fourth day, when I remembered the interval, even if the organs
