The two cases of placental tuberculosis which form the subject of this report are of unusual interest, for in each the disease was so slightly active as to be unrecognized clinically in the mother, but was found in the course of the routine microscopical examination of the placenta. In one instance no history suggestive of tuberculosis could be elicited and the disease, apparently incipient during pregnancy, has become latent since the birth of the child. This case, therefore, is similar to the one reported from this laboratory in 1913 by Dr. Warthin,1 in connection with which he at that time called attention to the increased importance of the sociologic and eugenic aspects of the transmission of tuberculosis from parent to child, provided that it can be shown that in women who have incipient or clinically unrecognizable tuberculosis the bacilli may enter the blood stream and cause
