Meek v. Breckenridge, 29 Ohio St 642; Harris v. Elliott, 10 Pet. 54, 9 I Ed. 333; Humphreys v. McKissock, 140 U. S. 304, 11 Sup. Ct. 779, 35 L. Ed. 473; Farmer v. Water Co., 56 Cal. 11. Appurtenances of a ship include whatever is on board a ship for the objects of the voyage and adventure in which she is engaged, belonging to her owner. Appurtenant is substantially the same in meaning as accessory, but it is more technically used in relation to property, and is the more appropriate word for a conveyance.
