PARTIAL PAYMENTS.

280. A PARTIAL PAYMENT is the payment of a part of the amount due on a note or bond. When partial payments are made, they are indorsed on the note or bond.

281, We shall now give the rule established in New York (see Johnson's Chancery Reports, vol. i., page 17,) for computing the interest on a bond or note, when partial payments. have been made. The same rule is also adopted in Massachusetts, and in most of the other States.

Rule.

I. Compute the interest on the principal to the time of the first payment; if the payment equals or exceeds this interest, add the interest to the principal, and from the sum subtract the payment; the remainder forms a new principal :

II. But if the payment is less than the interest, take no notice of it, except to indorse it on the note or bond, until other payments shall have been made, which in all, shall exceed the interest computed to the time of the last payment; then add the interest, so computed, to the principal, and from the sum subtract the sum of the payments; the remainder will form a new principal, on which interest is to be computed as before.
