Pehu and Chalier (1908, 1914 and 1915) from an extensive study of congenital tuberculosis accept only fifty-one cases as definitely proven. In the analysis of these cases they conclude that the father plays no part in the transmission, all the cases being the result of transplacental "heredocontagion." In all the cases admitted, the mothers had grave exacerbations of tuberculosis and they regard it as plausible that there was an acute generalization of the disease.
