easements

from Bouvier's Law Dictionary, Revised 6th Ed (1856)
EASEMENTS, estates. An easement is defined to be a liberty privilege or 
advantage, which one man may have in the lands of another, without profit; 
it may arise by deed or prescription. Vide 1 Serg. & Rawle 298; 5 Barn. &

     2. This is an incorporeal hereditament, and corresponds nearly to the 
servitudes or services of the civil law. Vide Lilly's Reg. h.t. 2 Bouv.
