Stephen Johnson Field,
Brick v. Brick — Opinion of the Court
“ As the equity, upon which the court acts in such cases, arises from the real character of the transaction, any evidence, written or oral, tending to show this is admissible. The rule which excludes parol testimony to contradict or vary a written instrument has reference to the language used by the parties. That cannot be qualified or varied from its natural import, but must speak for itself. The rule does not forbid an inquiry into the object of the parties in executing and receiving the instrument. ”
