T by will not only exercised a power already given her in favor of her husband but also any powers of appointment which she might derive from her father's will or otherwise. T's father subsequently executed a settlement allowing T to appoint to her husband "if she shall by deed or will appoint." T died without making a new will. Held, there was no valid exercise of the power, for the donor contemplated an act future to the settlement, as is shown by the words "if she shall." In re Bower, [1930] 2 Ch. 82.
