GESTATION, med. jur. The time during which a female, who has conceived, carries the embryo or foetus in her uterus. By the common consent of mankind, the term of gestation is considered to be ten lunar months, or forty weeks, equal to nine calendar months and a week. This period has been adopted, because general observation, when it could be correctly made, has proved its correctness. Cyclop. of Pract. Med. vol. 4, p. 87, art. Succession of inheritance. But this may vary one, two, or three weeks. Co. Litt. 123 b, Harg. & Butler's, note 190*; Ryan's Med. Jurisp. 121; Coop. Med. Jur: 18; Civ. Code of Louis. art. 203-211; 1 Beck's Med. Jur. 478. See Pregnancy.
