simple, &c., against an intruder. New Nat. Br. 453. 
    
from Bouvier's Law Dictionary, Revised 6th Ed (1856)
INTRUSION, estates, torts. When an ancestor dies seised of an estate of 
inheritance expectant upon an estate for life, and then the tenant dies, and 
between his death and the entry of the heir, a stranger unlawfully enters 
upon the estate, this is called an intrusion. It differs from an abatement, 
for the latter is an entry into lands void by the death of a tenant in fee, 
and an intrusion, as already stated, is an entry into land void by the death 
of a tenant for years. F. N. B. 203 3 Bl. Com. 169 Archb. Civ. Pl. 12; 
Dane's Ab. Index, h. t.
