Rom. 344 ; by accession, 1 Bouv. Inst. n. 499; 2 Kent., Com. 293; by intellectual labor, namely, for inventions, which are secured by patent rights and for the authorship of books, maps, and charts, which is protected by copyrights. 1. Bouv. Inst. n. 508.

4. Derivative acquisitions are those which are procured. from others, either by act of law, or by act of the parties. Goods and chattels may change owners by act of law in the cases of forfeiture, succession, marriage, judgment, insolvency, and intestacy. And by act of the parties, by gift or sale. Property may be acquired by a man himself, or by those who are in his power, for him; as by his children while minors; 1 N. Hamps. R. 28; 1 United States Law Journ. 513 ; by his apprentices or his slaves. Vide Ruth. Inst. ch. 6 & 7; Dig. 41, 1, 53; Inst. 2,9; Ib. 2,9,3.
