306 MEDICAL JURISPRUDENCE intermenstrual period. The child cried lustily at birth, had a good crop of hair, was well coated with vernix caseosa, measured twenty inches in length, and weighed seven pounds. The finger and toe nails were fully developed and the child sucked vigorously on being put to the breast. 2. The Maximum Period of Pregnancy.—Sometimes, cases of disputed legitimacy arise in which it is necessary to determine how long gestation may be prolonged. In In£ia, England and the United States of America the law does not lay down any fixed limit of gestation. Each case is decided on its own merits. J. K. Mohanty5 of Angul of the district of Cuttack reports the case of a Hindu woman, aged 36 years, who was delivered of a male child after a period of gestation of 315 days reckoned from the first day of her last menstrual period and nearly 300 days calculated from the probable day of ovulation or fertilization. The child was 22 inches long and weighed 9 pounds 6 ounces. The centres of ossification were visible in the upper epiphyses of the tibia and humerus in addition to that in the lower epiphysis of the femur. Dr. Phillips6 reports the case of a young unmarried girl in whom gestation lasted 324 days after the cessation of her last menstruation and 311 days after the date of coitus. A case 7 is also recorded where a healthy male child was delivered on the 315th day after the last date of intercourse. The husband had been killed on the same day, and compen- sation was claimed for the child. As there was no reason for doubting the chastity of the mother, the court entered judgment for the child, thus recognizing the possibility of a pregnancy of 320 days dating from the first day of the last menstrual period. In the divorce case s of Gaskill v. Gosfcill, the Lord Chancellor accepted 331 days as a period of protracted gestation. During the trial Eden said in his evidence that in cases of such prolonged pregnancy the child would be much above the average weight and dimen- sions at the time of birth. He cited six cases accepted as authentic in which the calculated period of gestation lay between 331 and 336 days, and the weights of the children varied from 12| to 13J pounds.9 But in this particular case the child was not weighed or measured. Four more cases of abnormally long periods of gestation have been reported. In one case10 pregnancy lasted 352 days calculated from the last menstrual period and probably 344 days from the coitus which resulted in the conception. In the second case n a primiparous woman, 27 years old, was delivered of a well- developed girl on the 343rd day after her last menstrual period. The girl was considerably, larger than the normal child, was 50 cm. long and weighed 5,000 grammes. In the third12 and fourth13 cases children born 346 and, 349 days after the last dates on which the couples actually cohabited were proved to be legitimate children. From very careful investigations carried out on 15,629 births, McKeown and Gibson14 have found that the longest periods of gestation were 319, 320, 321, 325 and 328 days. In two cases the period of gestation was reliably thought to be 339 and 359 days respectively. They also conclude that, for medico-legal purposes, a period of 354 days from coitus to the birth is not impossible. On the other hand, the House of Lords by a majority allowed the appeal of the husband, who brought a 5. ItwL Msd. Goz., Jan. 1944, p. 23. 6. Laturet 1900, Vol. I, p. 94. 7. J. F- Walker, Brit. Med.
