The determination by the court of common pleas, pursuant to Rev. Sts. c. 107, § 5, of how much is due to the plaintiff on the mortgage, on payment of which the defendant is to hold the premises, involves a mere computation of amounts, and, unless it appears on the face of the record that a question of law was involved in the decison, no appeal lies. St. 1840, c. 87, §§ 4, 5. Exceptions overruled.
