      [1913 Webster]

FIGURES, Numerals. They are either Roman, made with letters of the Alphabet, 
for example, MIDCCLXXVI; or they are Arabic, as follows, 1776. 
     2. Roman figures may be used in contracts and law proceedings, and they 
will be held valid; but Arabic figures, probably owing to the case with 
which they may be counterfeited, or. altered, have been holden not to be 
sufficient to express the sum due on a contract; but, it seems, that if the 
amount payable and due on a promissory note be expressed in figures or 
ciphers, it will be valid. Story on Bills, Sec. 42, note; Story, Prom. 
Notes, Sec. 21. Indictments have been set aside because the day or year was 
expressed in figures. 13 Vin Ab. 210; 1 Ch. Rep. 319; S. C. 18 Eng. Com. Law

     3. Bills of exchange, promissory notes, cheeks and agreements of every 
description, are usually dated with Arabic figures; it is, however, better 
to date deeds and other formal instruments, by writing the words at length.
