delivered the opinion of the Court.
This is a suit to recover the amount of taxes alleged to have been illegally collected under the Revenue Act of 1918, February 24, 1919, c. 18, 40 Stat. 1057, in view of the deductions , allowed by § 403 (a) (3), 40 Stat. 1098. The Court of Claims denied the claim,

On. Juñe 15, 1921, Edwin C. Stewart died, appointing his wife and the Ithaca Trust Company executors, and the Ithapa Trust Company trustee of the trusts created by his will. He gave the residue of his estate to his wife for life with authority to use from the principal any sum
“
that may be necessary- to suitably maintain her in as much comfort as she now enjoys.” After the death of the wife there were bequests in trust for admitted charities. The case presents-two questions the first of which is whether the provision for the maintenance of the wife made the gifts to charity so uncertain that the deduction of the amdunt of those gifts from the gross estate under § 403 (a) (3),
supra,
in order to ascertain the estate tax, cannot be allowed.

v.
United States,
The second question is raised , by the accident of the widow having died within the year granted by the statute, § 404, and regulations, for filing the return showing the deductions allowed by § 403, the value of the net estate and the tax paid or payable thereon. By § 403 (a) (3) the net estate taxed is. ascertained by deducting, among other things, gifts to charity such as were made in this case. But as those gifts were subject to the life estate of the widow, of course their value was diminished, by the postponement that would last while the widow.

lived. The question is whether the amount of the diminution, that is, the length of the postponement, is to be determined by the event as it turned out, of the widow’s death within six months, or by mortality tables showing the probabilities as they stood on the day when the testator died. The first impression is that it is absurd to resort to statistical probabilities when you know the fact. But this is due to inaccurate thinking. The estate so far as may be is settled as of the date of the testator’s death. See
