Promissory note. A written engagement by one person to pay unconditionally to another therein
named (or to his order or to the bearer) a certain sum of money at a specified time. A note bears
interest before maturity only when so stated. "Value received" is usually written in a note but is not
necessary; if not written it is presumed by the law to be or the deficiency may be supplied by proof.
If the amount stated in words and the amount stated in figures do not agree the words govern.
