Young speaks of a woman who three months previously had aborted a three months' fetus, but a tumor still remained in the abdomen, the auscultation of which gave evidence of a fetal heart-beat. Vaginal examination revealed a dilatation of the os uteri of at least one inch and a fetal head pressing out; subsequently a living fetus of about six months of age was delivered. Severe hemorrhage complicated the case, but was controlled, and convalescence speedily ensued. Huse cites an instance of a mother bearing a boy on November 4, 1834, and a girl on August 3, 1835. At birth the boy looked premature, about seven months old, which being the case, the girl must have been either a superfetation or a seven months' child also. Van Bibber of Baltimore says he met a young lady who was born five months after her sister, and who was still living. The most curious and convincing examples of superfetation are those in which children of different colors, either twins or near the same age, are born to the same woman,--similar to that exemplified in the case of the mare who was covered first by a stallion and a quarter of an hour later by an ass, and gave birth at one parturition to a horse and a mule. Parsons speaks of a case at Charleston, S.C., in 1714, of a white woman who gave birth to twins, one a mulatto and the other white. She confessed that after her husband left her a negro servant came to her and forced her to comply with his wishes by threatening her life. Smellie mentions the case of a black woman who had twins, one child black and the other almost white. She confessed having had intercourse with a white overseer immediately after her husband left her bed. Dewees reports a similar case. Newlin of Nashville speaks of a negress who bore twins, one distinctly black with the typical African features, while the other was a pretty mulatto exhibiting the distinct characters of the Caucasian race. Both the parents were perfect types of the black African negro. The mother, on being questioned, frankly acknowledged that shortly after being with her husband she had lain a night with a white man. In this case each child had its own distinct cord and placenta.
