No future interest, valid in its creation, is defeated by the determination of the precedent interest before the happening of the contingency on which the future interest is limited to take effect, but should such contingency afterwards happen, the future interest takes effect in the same manner and to the same extent as if the precedent interest had continued to the same period.
