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

FEOFFMENT, conveyancing. A gift of any corporeal hereditaments to another.
It operates by transmutation of possession, and it is essential to its
completion that the seisin be passed. Watk. Prin. Conv. 183. This term also
signifies the instrument or deed by which such hereditament is conveyed.
     2. This instrument was used as one of the earliest modes of conveyance
of the common law. It signified, originally, the grant of a feud or fee; but
it came, in time, to signify the grant of a free inheritance in fee, respect
being had to the perpetuity of the estate granted, rather than to the feudal
tenure. The feoffment was, likewise, accompanied by livery of seisin. The
conveyance, by feoffment, with livery of seisin, has become infrequent, if
not obsolete, in England; and in this country it has not been used in
practice. Cruise, Dig. t. 32, c. 4. s. 3; Touchs. c. 9; 2 Bl. Corn. 20; Co.

denominated the feoffee. 2 Bl. Com. 20. See 2 Bouv. Inst. n. 2045, note.
