VENTER INSPICIENDO, Eng. law. A writ directed to the sheriff, commanding him
that, in the presence of twelve men, and as many women, he cause examination
to be made, whether a woman therein named is with child or not; and if with
child, then about what time it will be born; and that he certify the same.
It is granted in a case when a widow, whose husband had lands in fee simple,
marries again soon after her husband's death, and declares herself pregnant
by her first husband and, under that pretext, withholds the lands from the
next heir. Cro. Eliz. 506; Fleta, lib. 1, c, 15.
