and firm poffeffion. And, after conveyance by deed came 
into ufe, thefe inveftitures were retained as a public and

teftify the transfer of the eltate, and that fuch as claimed 
title by other means might know againft whom to bring

was to be transferred ; as lands paffed by the delivery of

titure ; after which they were confecrated by ecclefiaftical 
perfons. Hoveden tells us, that king Richard, being taken
