In many cases the seminal ducts have become so weak and relaxed that the fluid passes off involuntarily with the water and is not perceived; also when straining at stool and when you have an erection. To test its escape in the urine, pass off your water in a clear glass pint bottle and let it stand twenty-four hours in a warm place; then hold up the bottle between yourself and the light, and if you discover a sediment of a +white, fleecy+ nature, resembling cotton, in the bottom, you are suffering from +hidden spermatorrhoea+, from which all your present ailments come. Where this fluid passes off with the urine, it is just as injurious to the system as full emissions, as it is a continual drain day after day, as well as taking that part of the vitality which goes to supply the brain and nerves. Many patients afflicted in this way will notice, shortly after urinating, a +dull pain+ in the forehead, sometimes extending to the +eye-balls+, causing, as well, a feeling of +general debility+, as if they had no strength or will to do anything. If this weakness is allowed to go on unchecked, the mind will become diseased, the eye-sight will be impaired, and the vital forces consumed--thereby causing +partial and complete impotency+. Should you desire greater certainty in testing, either send on a sample of your urine, or test it with our powder. The characteristic symptoms of partial impotency are: an imperfect erection, or, if the erection is sufficiently vigorous, it is of too short a duration, and the vital fluid is discharged prematurely. The erector muscles become paralyzed, and the organ remains inactive at the call of the will. The person thus afflicted is greatly embarrassed and mortified at his paralytic condition. That buoyancy of spirit is gone; the snap, vim and vigor that once held sway has departed--and why? Because that great motive power (amativeness) that gives the push and go-aheaditiveness is checked, or rather, ceases to act. THE CURABILITY OF SPERMATORRHOEA AND IMPOTENCY. Having before us the records of some three thousand cases, grave, simple and severe, that have come under our treatment in this country, as well as the printed copies of the +French Hospital Reports+, and +Civiale's Works+, in which he minutely reviews all phases of this complaint, illustrating them with cases from his own practice, we feel justified in assuring our readers that almost any case can be cured, provided +thoroughness+ is the maxim of treatment.
