A new promise made either before or after the statute has completely run extends the period of limitation for the statutory period.8 The same rule prevails almost universally in regard to acknowledgments. Though here distinctions have been suggested: It has with some reason been urged that an acknowledgment before the statute had run when there was no defence possible and the debtor's liability was undeniable, should not justify the inference of a new promise or have any effect other than its obvious one of an admission that at the time of speaking, the debtor owed what he admitted.9 Curi-ously enough a distinction precisely the opposite is actually taken in a few States; namely, that after a debt is once barred, an acknowledgment is insufficient to revive the debtor's liability. A new promise is then necessary,10 though before the period of limitation had expired an acknowledgment would be sufficient to start time running afresh.
