The author thinks iodide of stannum often preferable to stannum in tuberculosis. He uses it when the patient has a clear complexion and long eyelashes and where the progress of the disease is rapid. He reports a case for which the 2x trituration was given, in which there was “a marked tubercular affection of the chest, increased vocal fremitus, an abundance of thick yellow and sweetish sputum, sweat at night, and rapid emaciation.” The result was encouraging.
