Izaak Walton relates about Bishop Sanderson, that once "his dear and most intimate friend, the learned Dr. Hammond, came to enjoy a quiet rest and conversation with him for some days at Boothby Pannel, and did so, and having formerly persuaded him to trust his excellent memory, and not read, but try to speak a sermon as he had writ it; Dr. Sanderson became so compliant as to promise that he would. And to that end they two went early the Sunday following to a neighbour minister, and requested to exchange a sermon; and they did so. And at Dr. Sanderson's going into the pulpit, he gave his sermon (which was a very short one) into the hands of Dr. Hammond, intending to preach it as it was writ; but before he had preached a third part, Dr. Hammond (looking on his sermon as written) observed him to be out, and so lost as to the matter, especially the method, that he also became afraid for him; for it was discernible to many of that plain auditory. But when he had ended this short sermon, as they two walked homeward, Dr. Sanderson said with much earnestness, 'Good Doctor, give me my sermon, and know that neither you, nor any man living, shall ever persuade me to preach again without my books.' To which the reply was, 'Good Doctor, be not angry; for if ever I persuade you to preach again without book, I will give you leave to burn all the books that I am master of.'" Elsewhere Walton says:--"Though they were much esteemed by them that procured and were fit to judge them, yet (Dr. Sanderson's sermons) were the less valued because he read them, which he was forced to do; for though he had an extraordinary memory (even the art of it), yet he was punished with such an innate, invincible fear and bashfulness, that his memory was wholly useless as to the repetition of his sermons, so as he had writ them; which gave occasion to say, when some of them were first printed and exposed to censure (which was in the year 1632), that the best sermons that ever were read were never preached." Aubrey says, that when he was a freshman at college, and heard Dr. Sanderson read his first lecture, he was out in the Lord's Prayer. CHRISTIAN NAMES AMONG THE PURITANS.
