Abstract

Sir, I Am so much oblig’d to you for your many Favours when I was with you; that now, when I am at so great a distance from Oxon , I cannot pass by any oportunity of serving you, in visiting the Curiosities of Art or Nature (with which the Northern parts, Durham , and Cumberland especially, do abound) and in giving you an account of what, I judge, may be worth your knowledge.
