140Bequest of fund for certain purposes, some of which cannot be fulfilled.

Where a testator does not absolutely bequeath a fund, so as to sever it from his own estate, but gives it for certain purposes, and part of those purposes cannot be fulfilled, the fund, or so much of it as has not been exhausted upon the objects contemplated by the will, remains a part of the estate of the testator.

The son dies without having ever had a child. The fund, after the son's death, belongs to the estate of the testator.
(ii) A bequeaths the residue of his estate, to be divided equally among his daughters, with a direction that they are to have the interest only during their lives, and that at their decease the fund shall go to their children. The daughters have no children. The fund belongs to the estate of the testator.
