      July, 1830.
    — Scire facias to revive judgment, before Benjamin Johnson, Thomas P. Eskridge, and Edward Cross, judges.
   Opinion oe the Court. — The only question to be decided, is as to the mode of calculating interest.

We are of opinion that the correct mode of easting interest when partial payments have been made, is to apply the payment in the first place to the discharge of the interest then due, and if the payment exceeds the interest, the surplus goes towards discharging the principal, and the subsequent interest is to be computed on the balance of principal unpaid. If the payment be less than the interest, the surplus interest must not be taken to augment the principal, but interest continues on the principal until the period when the payments taken together exceed the interest due, and then the surplus is to be applied towards discharging the principal, and the interest is to be computed on the balance of principal as above stated. 1 Dallas, 124; 1 Halsted, 408; 2 Wash.
