Abstracts. Venereology and Dermatology. Hugo Bauer (D. Z. Bd. 57, H. 4, 29), aiming to study the secretion of myosalvarsan'a, took under observation 4 syphilitics treated with injections of the drug. Excretion of myosalvarsan'a, as well as its absorption, is similar to 'neo' and sulfoxylsalvarsan'y. Most of the arsenobenzol'a introduced into the body is released within a "short time" after injection; four weeks after the cessation of treatment, the body is freed from the maximum amount of introduced As. The author believes that the clinical observations, on the basis of which it is argued that if certain intervals are observed between courses, the cumulative action of As does not occur, are completely fair. The author gives a detailed technique for determining As in selections and supplies the article with visual tables and curves of his own observations.
