“Grants, concessiones; the regular method by the common law of transferring the property of incorporeal here-ditaments, or, such things whereof no livery can be had. For which reason all corporeal hereditaments, as lands and houses, are said to lie in livery; and the others, as advowsons, commons, rents, reversions, etc., to lie in grant…. These therefore pass merely by the delivery of the deed.” 2 William Blackstone, Commentaries on the Laws of England 317 (1766).
