Hahnemann made a separate proving of Merc. ac., which has furnished a few symptoms, not greatly differing from those of Merc. The throat lancinations were < by coughing rather than by swallowing. Cold water < the inflammation of the penis; bathing with tepid water >. Hahnemann has bracketed a symptom referring to the menses which came on at the new moon, four days before their proper time. The medicines whose action is influenced by the moon's phases are not numerous, and this is worth remembering. "Pressure in lower sternum and dyspnœa on standing erect" is a noteworthy symptom. "Margins of ulcers become painful." Hansen says that "burning in the urethra during urination and at other times" has been confirmed in practice; and that Donner of Stuttgart has cured with it a very painful syphilitic ulcer in urethra. Hansen commends it in tinea favosa on a syphilitic base; and for lancinating pains in tabes syphilitica.
