Dined at Sir Gabriel Sylvius's and thence to visit the Duke of Norfolk, to ask whether he would part with any of his cartoons and other drawings of Raphael, and the great masters; he told me if he might sell them all together he would, but that the late Sir Peter Lely (our famous painter) had gotten some of his best. The person who desired me to treat for them was Vander Douse, grandson to that great scholar, contemporary and friend of Joseph Scaliger.
