See quotation. Fourfold (v.) is given by Webster, 1806: N.E.D.
1821. If the proprietor gives in a false list, he is punished by having the falsified article increased on the list four-fold. Englishmen on both sides of the Atlantic, have no fondness for circumlocution. We therefore style this punishment Four-folding.—T. Dwight, ‘Travels,’ iv. 285. (Italics in the original.)
