the running of a gonorrhea stopping suddenly after it appears. When it thus stops, a pain reaches to the anus, or to the testicles, without their being swelled; and sometimes this pain reaches to the bladder, in which case there is an urging to discharge the urine, which is with difficulty passed, and in very small quantities at a time. The pain is continued to the bladder by the urethra; to the anus, by the acc- eleratory muscles of the penis; and to the testicles, by the vasa deferentia, and vesicula seminales. In this case, calomel repeated so as to purge, brings back the running, and then all difficulty from this symptom ceases.
