_Stricture_, deep in the canal, causing congestion and inflammation; _Masturbation_, by keeping the gland excited, congested and irritated, often causes it; _Exposure to cold and wet_, especially sitting on a cold door-step or damp seat; _Blows and Injuries_ of any kind; _Strong Injections_, and rough jabbing with steel sounds or rough bougies; _Eating Hot Condiments_, or too free indulgence in alcoholic beverages. VARIOUS COMPLICATIONS. If the inflammation extends to the neck of the +bladder+, he has an attack of +cystitis+. If it goes down along the seminal ducts, it produces +swelled testicle+, +clogged duct+, +chronic enlargement+, +cancer+, +cysts+ and hopeless wasting of the +testicles+. If it extends up the +ureters+, it causes +Bright's Disease+, +abscess+ of the +kidneys+, or +lumbar fistula+. If it runs forward along the urine canal, it produces so-called +gleet+. If it settles in the +prostate gland+ and becomes chronic, it may cause +abscess of the gland+, +retention of the urine+, and certainly either or both +Spermatorrhoea+ or +Impotency+. It may thus be seen how exceedingly dangerous a disease this +Prostatitis+ is, and how very important it becomes to check it at the earliest possible moment. SYMPTOMS.--We have space for but the most prominent and frequent ones: a +dull, aching, dragging+ or +throbbing pain+ between the legs, made worse by +standing, walking, jolting+, &c., and sometimes relieved by hard pressure, or lying down with one's feet higher than their head; pain, burning or smarting on passing urine; +twisting+ of the stream; the oozing of a thin, glairy fluid; +sticking+ together of the lips of the mouth of the urinal canal; +soreness, aching or tenderness+ of one or both +testicles+; dull pain or ache in +the small of the back+ or +buttocks+; +dizziness, sudden fits of exhaustion, convulsions, coma and death+. A +microscopical examination+ of the urine will reveal the nature of the difficulty in a moment. There also will be found evidences of great +nervous wear and tear, and seminal losses+, more or less constant. {Illustration: L'ECOLE DE MEDICINE, PARIS. The most celebrated Medical College in France, in which both +Civiale+ and +Lallemand+ were Professors.} GLEET AND STRICTURE AS A CAUSE OF SPERMATORRHOEA AND IMPOTENCY. These two diseases are probably less understood than almost any other equally common. It is safe to say that at least one man out of every ten has, has had, or will have one or both. Neglected gleet often causes stricture; neglected or improperly treated stricture often causes and keeps up a gleet. Another set of statements, equally sweeping and based upon the best of medical evidence, may be made, _i.e._, more cases of gleet and stricture are caused by Self-Abuse (masturbation, Onanism), and sexual excesses than by gonorrhoea--formerly and ignorantly supposed to be about the only cause.
