'Whoever he was that observed that (in the last chapter of my third book) I had not made so just an acknowledgment of your assistance as I ought to have done, is perhaps in the right: tho’ I dare say ’tis more than he could be assur’d of. here were several observations in my Ld A. Bps papers which I had hit upon before I saw them, as his Grace well knowes, who had the perusal of my notes before he was pleas’d to communicate his own. I must ever acknowledge that he gave me the opportunity of correcting many mistakes and made discoveries to which I was a perfect stranger, and (possibly) I have not so frequently own’d his Grace’s help as I was oblig’d in gratitude to have done. But I can justly protest that I did not wittingly omit any respect that was either to his Grace or yourself.' (Thoresby 1912, pp. 65-7; Burnett 2020b, p. 904 n. 173)
