Sanger mentions a triple ectopic gestation, in which there was twin pregnancy in the wall of the uterus and a third ovum at the fimbriated end of the right tube. Careful examination showed this to be a case of intramural twin pregnancy at the point of entrance of the tube and the uterus, while at the abdominal end of the same tube there was another ovum,--the whole being an example of triple unilateral ectopic gestation. The instances of delivery of an extrauterine fetus, with viability of the child, from the abdomen of the mother would attract attention from their rarity alone, but when coupled with associations of additional interest they surely deserve a place in a work of this nature. Osiander speaks of an abdominal fetus being taken out alive, and there is a similar case on record in the early part of this century. The London Medical and Physical Journal, in one of its early numbers, contained an account of an abdominal fetus penetrating the walls of the bladder and being extracted from the walls of the hypogastrium; but Sennertus gives a case which far eclipses this, both mother and fetus surviving. He says that in this case the woman, while pregnant, received a blow on the lower part of her body, in consequence of which a small tumor appeared shortly after the accident. It so happened in this case that the peritoneum was extremely dilatable, and the uterus, with the child inside, made its way into the peritoneal sac. In his presence an incision was made and the fetus taken out alive. Jessop gives an example of extrauterine gestation in a woman of twenty-six, who had previously had normal delivery. In this case an incision was made and a fetus of about eight months' growth was found lying loose in the abdominal cavity in the midst of the intestines. Both the mother and child were saved. This is a very rare result. Campbell, in his celebrated monograph, in a total of 51 operations had only seen recorded the accounts of two children saved, and one of these was too marvelous to believe. Lawson Tait reports a case in which he saved the child, but lost the mother on the fourth day. Parvin describes a case in which death occurred on the third day. Browne quotes Parry as saying that there is one twin pregnancy in 23 extrauterine conceptions. He gives 24 cases of twin conception, one of which was uterine, the other extrauterine, and says that of 7 in the third month, with no operation, the mother died in 5. Of 6 cases of from four and a half to seven months' duration, 2 lived, and in 1 case at the fifth month there was an intrauterine fetus delivered which lived. Of 11 such cases at nine months, 6 mothers lived and 6 intrauterine fetuses lived. In 6 of these cases no operation was performed. In one case the mother died, but both the uterine and the extrauterine conceptions lived. In another the mother and intrauterine fetus died, and the extrauterine fetus lived.
