340 MEDICAL JURISPRUDENCE the skin was peeling off at several places. The uterus was inverted and protruding from the vagina. The foetus was a male of five months of intra-uterine life with the placenta and cord (ten inches long) intact, and attached to the umbilicus. Brown11 reports the case of a pregnant woman who had been dead about 60 hours before her body was found. There were signs of putrefaction in the skin and general emphysema. The vagina was not gaping. During the removal of the body from the hut, an eight months' foetus, weighing 6 pounds, was spontaneously expelled. The inverted uterus prolapsed, showing the placenta still attached. There was no tear of the perinzeum. The uterus was normal. The foetus showed slight peeling of the epidermis but otherwise no signs of putrefaction. R. Nagendran 12 reports the case of a widow, 35 years old, who died of drowning in a tank. At the end of three days the body floated to the surface and was removed by the police for investigation and examination. Post-mortem examination was held twelve hours after the inquest. The body was decomposed. Protruding through the vagina and hanging down was a foetus with the umbilical cord, 13 inches long. The entrance to the vagina was plugged by the placenta. On further examination it was found that the uterus had prolapsed and completely everted, lying hi the vaginal canal with the placenta still adhered to the fundus. The material alleged to have been expelled from the Uterus. — When ^a substance alleged to have been expelled from the uterus as a product of Conception is sent to the medical man for his opinion, he should thoroughly wash w it in water to determine if it is a foetus or merely a blood clot, a shred of the dysmenorrhoeal membrane, a polypus, or a fibroid tumour. In a doubtful case a small portion of the suspicious material should be cut off, mounted on a slide in water or glycerin and examined under the low power of a microscope.\ I have often examined blood clots wrapped up in pieces of cloth alleged to be foetuses, and brought by women, who reported to the - police that they had miscarried as the result of an assault or a kick on the hypogastrium. In one case a woman complained that owing to the injuries inflicted on her abdomen during a quarrel she aborted, and brought for my examination a^piece of cloth ^contaiiimgjbjgodclots^aijd^ tissue_allgged-4e--:be a foetusT^^ wasTSuncf to be a piece of tumour. There was also no injury to the abdo- men. In order to aggravate the offence women generally complain of mis- carriage having occurred from an assault, when they are having their menses at the time of the struggle or when the menstrual flow has followed it. In the early months of pregnancy if the embryo is not found, the presence of chgrionic^yilli found under the low power of a microscope will decide the fact of miscarriage. It should be remembered that during the first three months of pregnancy the foetus is expelled with its membranes en masse, but after this period the foetus is born first and then after a time the placenta is detached and expelled, a portion of which may remain adherent to the uterus. If the placenta is sent along with the foetus, it should be examined to ascertain if it is entire or torn at any place, and if there are any degenerative changes on its surface. K it is a ^foetus, it is necessary to detennine its probable intra-uterine age, its viability and the presence or absence of wounds or injuries inflicted on the body.
