GRAND COUTUMIER. Two collections of laws bore this title. The one, also
called the Coutumier of France, is a collection of the customs, usages, and
forms of practice, which had been used from time immemorial in France: the
other, called the Coutumier de Normandie, which indeed made a part of the
former, with some alterations, was composed about the fourteenth of Henry
II., in 1229, and is a collection of the Norman laws not as they stood at
the Conquest of England, by William the Conqueror, but some time afterwards,
and contains many provisions, probably borrowed from the old:English or
Saxon laws. Hale's Hist. C. L. c. 6.
