A written instrument will be reformed in equity when it fails to express the intention which the parties had in making the contract which it purports to contain. Minot v. Tilton,
There is no presumption that in the determination of this disputed fact the referee has violated elementary rules. We cannot assume the referee would have made the explicit finding which he has made except by the application of so familiar principles. He must have been satisfied "there was a plain mistake, clearly made out by satisfactory proofs" (1 Sto. Eq. Jur., s. 157), or the presumption arising from the written expression of intent would not have been found to have been overbalanced. If he was not so satisfied, his finding is against the weight of the evidence. But the report does not appear to have been attacked on that ground, and cannot be so attacked at the law term. Dodge v. Stickney,
Exception overruled.
BLODGETT, C. J., did not sit: the others concurred. *Page 533
