Usufruct

In the civll law. The right of enjoying a thing, the property of which is vested in another, and to draw from the same all the profit, utility, and advantage which it may produce, provided it be without altering the substance of the thing. Civ. Code La. art. 533. And see Mulford v. Le Franc, 26 Cal. 102 ; Cartwright v. Cartwright, 18 Tex. 628; Strausse v. Sheriff, 43 La. Ann. 501, 9 South. 102.

— Imperfect usufruct. An imperfect or quasi usufruct is that which is of things which would be useless to the usufructuary if hg did not consume or expend them -or change the substance of them; as, money, grnin, liquors. Civ. Code La. 1900, art. 534.

— Perfect usufruct. An usufruct in those things which the usufructuary can enjoy without changing their substance, though their substance may be diminished or deteriorate naturally by time or by the use to which they are applied, as, a house, a piece of land, furniture, and other movable effects. Civ. Code La. 1900, art. 534.

— Quasi usufruct. In the civil law. Originally the usufruct gave no right to the substance of the thing, and consequently none to its consumption; hence only an inconsumable thing could be the object of it, whether movable or immovable. But in later times the right of usufruct was, by analogy, extended to consumable things, and therewith arose the distinction between true and quasi usufructs. See Mackeld. Rom. Law, § 307; Civ. Code La. 1900. art. 534.
