Hereditaments

Every kind of property that can be inherited, i.e., all such immovable things, whether corporeal or incorporeal, which a man may have to him and his heirs by way of inheritance, and which, it they are  not otherwise devised, descend to him that is next heir, and fall not to the executor as chattels do.  It is a word of very great extent comprehending whatever may be inherited or come to the heir, be it real personal or mixed, and though it is not holden, or lies not in tenure.  By the grant of hereditaments in conveyance, manors, houses, and lands of all sorts, rents services, advowsons, etc. 

Herditaments are corporeal and incorporeal.   Corporeal consist of such as affect the senses; such as may be seen and handled by the body; in fact they mean the same thing as land.  Incorporeal are not the object of sensation, can neither be seen nor handled, are creatures of the mind, and exist only in contemplation; such as rights and profits annexed to issuing out if concerning or exercisable with land; they are not the things corporate themselves, but something collateral thereto.
