"Good Reader, I suspect I may have written some Things twice; if not the same in Words, yet in Sense, which I desire you to pass by favourably; forasmuch as you may well think, it was as difficult and dull a Thing for me, in so great a Number of independent Sentences, to find out the Repetitions, as it would be in a vast Heap of different Coins and Medals, confusedly thrown together, to pick out here and there one that bore the same and like Inscription, with some other among them. Besides the Pains, such a Search would cost me more Time, than I can afford it; for my Glass of Life running now low, I must not suffer one Sand to fall in waste, nor spend one Minute in picking of Straws. And moreover, my aged Eyes being grown weak and dim, I fear they will become quite dark, by much perusing and poring; or at least so far, so as to render me unable to perfect several Papers now lying by me, which I would willingly make a Present of to you."
