An extensive proving of Zn. o. was made by Wernek, Buchner, and Michælis. These symptoms have been included by Allen in the pathogenesis of Zincum, and some of them will be found in my Schema of Zincum. Jahr kept a separate record of Zn. o. I append his account. The contracting, shrivelling-up effect of Zinc was marked in these provings. Among the more Peculiar Symptoms were: Undulating movement in some muscles. Contraction of the risible muscles and constant impulse to laugh. Teeth blunted; incisors feel soft and glued together. Hiccough, > after regurgitation of bile. Liquid stools which > all symptoms. In these provings the left lung was very markedly affected. There was coryza < after a meal, with difficulty of respiration and nasal secretion. Stoppage of the nose was much complained of. Anorexia > after a meal. Farrington says Zn. o. is very like Con. in hypochondriasis and melancholy from masturbation, the difference being that Zn. o. is irritating as well as weakening and depressing.
