The recognition becomes largely a question of chance. Most embryonic deaths pass unseen. In such early deaths the embryonic sac is by far the greatest and most conspicuous part. Frequently the embryo dies and all traces of it disappear while its sac persists and apparently con- tinues to grow. The embryonic sac retains its usual form, but is without evident placental structure, and apparently maintains its growth and existence by absorption of liquids from the uterine cavity. One of these is illustrated in Fig. 169—Cystic Mole. Total length 46 inches ; circumference, 7 inches. At the top of the gravid branch of the fetal sac is seen a thickened spot, apparently marking the former location, of the embryo. Compare with colored plate II. At the cervical end of the uterus, the embryonic sac is necrotic and desiccated. The necrotic tips are prominent. .Sac removed 200 days after conception. 169. In this instance there remains a thickened area which faintly suggests the prior location of the embryo. The cow was examined at about sixty days after coitus and pro- nounced pregnant. The cervical canal was sealed, the uterus enlarged and distended in a manner typical of pregnancy of that duration, a typical corpus luteum of pregnancy was present, and estrum was absent. The general signs of preg- nancy failed to advance parallel to the duration of time. Later an examination disclosed the nature of the condition, and the "mole" was Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Williams, W.
