"My Lord, "Your hours are so well employed, I hardly dare offer you this trifle to look over; but then, so well am I acquainted with the sweetness of temper which accompanies your learning, I dare ever assure myself of a pardon.

You have already forgiven me greater impertinencies, and condescended yet further in giving me instructions and bestowing some of your minutes in teaching me.

This surprising humility has all the effect it ought to have on my heart; I am sensible of the gratitude I owe to so much goodness, and how much I am ever bound to be your servant.

Here is the work of one week of my solitude--by the many faults in it your lordship will easily believe I spent no more time upon it; it was hardly finished when I was obliged to begin my journey, and I had not leisure to write it over again.

You have it here without any corrections, with all its blots and errors: I endeavoured at no beauty of style, but to keep as literally as I could to the sense of the author.
