Another very interesting specimen of tubal implantation is No. 1771, received from Dr. H. M. N. Wynne, of the Johns Hopkins Hospital. The menstrual age of this specimen is 49 days, but its anatomic age, as based upon length according to Dr. Streeter's curve (unpublished), is 37 days, thus showing a discrepancy between the menstrual and anatomic ages of 12 days. The embryonic length is only 12.5 mm., although with a menstrual age of 49 days it should be at least 18 mm. Upon examination, Dr. Streeter found the chorionic vesicle to contain a good deal of magma, some of which still was adherent to the embryo, as figure 3 shows. As has been repeatedly emphasized in the literature, the presence of this coagulum in itself probably indicates that the embryo died some time previously.
