Smith Thompson,
Keene v. Meade — Opinion of the Court
“ It cannot be laid down as a universal rule, that where written evidence of a fact exists, all parol evidence of the same fact must be excluded. Suppose the defendant had written a letter to the plaintiff acknowledging the receipt of the money, it certainly could not be pretended that the production of this letter would be indispensable, and exclude all parol evidence of the advance. ”
