"But yit I can not bult it to the bren."
And Spenser, Faery Queene, iv. 24:
"He now had boulted all the floure."
"Time and nature will bolt out the truth of things."—D'Estrange. "To boulte out the truth in reasoning, limare veritatem in disceptatione."—Baret's Alvearie.

There was a term "boultings" or "boltings," used of private arguings of cases in some of the Inns of Court. "Boulter, a sifter."—Coles' Dict. 1676.
