DEAD-BORN, descent, persons. Children dead-born are considered, in law, as if they had never been conceived, so that no one can claim a title, by descent, through such dead-born child. This is the doctrine of the civil law. Dig. 50, 16, 129. Non nasci, et natum mori, pare, sunt. Mortuus exitus, non est exitus. Civil Code of Louis. art. 28. A child in ventre sa mere is considered in being, only when it is for its advantage, and not for the benefit of a third person. The rule in the common law is, probably, the same, that a dead-born child is to be considered as if he had never been conceived or born in other words, it is presumed he never had life. it being a maxim of the common law, that mortuus exitus non est exitus. Co. Litt. 29 b. See 2 Paige, R. 35; Domat, liv. prel. t. 2, s. 1, n. 4, 6; 4 Ves. 334.

DEAD FREIGHT, contracts. When the charterer of a vessel has shipped part of the goods on board, and is not ready to ship the remainder, the master, unless restrained by his special contract, may take other goods on board, and the amount which is not supplied, required to complete the cargo, is called dead freight.

2. The dead freight is to be calculated according to the actual capacity of the vessel. 3 Chit. Com. Law; 399 Stark. 450.

DEAD MAN'S PART, English law. By the custom of London, when a deceased freeman of the city left a widow and children, after deducting what was calledthe widow's chamber, (q.v.) his personal property was divided into three parts; one of which belonged to the widow, another tot he children, and the third to the administrator. When there was only a widow, or only children, in either case they respectively took one moiety, and the administrator the other; when there was neither widow nor child, the administrator took the whole for his own use and this portion was called the "dead man's part." By statute of 1 Jac. 2, c. 17, this was changed, and the dead man's part is declared to be subject to the statute of distribution. 2 Bl. Com. 518. See Bac. Ab. Customs of London, D 4.

DEAD LETTERS. Those which remain in the post-office, uncalled for. By the Act of March 8, 1825, 3 Story. L. U.
