Somewhat later it was again removed to Durham, where it remained for several centuries.
The second MS.

is called the Rushworth MS., as it was presented to the Bodleian Library (Oxford) by John Rushworth, who was deputy-clerk to the House of Commons during the Long Parliament.

The gloss, written in the latter half of the tenth century, is in two hands, those of Farman and Owun, whose names are given.
