from Bouvier's Law Dictionary, Revised 6th Ed (1856)

OUSTER, torts. An ouster is the actual turning out, or keeping excluded, the 
party entitled to possession of any real property corporeal. 
     2. An ouster can properly be only from real property corporeal, and 
cannot be committed of anything movable; 1 Car. & P. 123; S. C. 11 Eng. Com. 
Law R. 339; 2 Bouv. 1 Inst. n. 2348; 1 Chit. Pr. 148, note r; nor is a mere 
temporary trespass considered as an ouster. Any continuing act of exclusion 
from the enjoyment, constitutes an ouster, even by one tenant in common of 
his co-tenant. Co. Litt. 199 b, 200 a. Vide 3 Bl; Com. 167; Arch. Civ. Pl. 
6, 14; 1 Chit. Pr. 374, where the remedies for an ouster are pointed out. 
Vide Judgment of Respondent Ouster.
