Things personal include not only things movable, but also something more, the whole of which is generally comprehended under the name of chattels. Chattels are distinguished into two kinds, namely, chattels real and chattels personal. It is proper to remark that sometimes it depends upon the destination of certain objects, whether they are to be considered personal or real property. Formerly, in England, a very low and contemptuous opinion was entertained of personal property, which was regarded as only a transient commodity. Things in patrimonio are divided into corporeal and incorporeal, and the corporeal again into movable and immovable.
Corporeal things are either movable or immovable.
The movable are those which have been separated from the earth, as felled trees, or gathered fruits, or stones dug out from quarries or those which are naturally separated, as an-imals. Things extra patrimonium are, 1. Things common are, the heavens, light, air, and the sea, which cannot be appropriated by any man or set of men, so as to deprive others from the. use of them. Things public, res publicae, the property of which was in the state, and their use common to all the members of it, as navigable rivers, ways, bridges, harbors, banks, and the right of fishing. Res universitatis, or things belonging to cities or bodies politic.
