My father had a small estate in Nottinghamshire; I was the third of five sons. He sent me to Emmanuel College in Cambridge at fourteen years old, where I resided three years, and applied myself close to my studies; but the charge of maintaining me, although I had a very scanty allowance, being too great for a narrow fortune, I was bound apprentice to Mr. James Bates, an eminent surgeon in London, with whom I continued four years; and my father now and then sending me small sums of money, I laid them out in learning navigation, and other parts of the mathematics useful to those who intend to travel, as I always believed it would be, some time or other, my fortune to do. When I left Mr. Bates, I went down to my father, where, by the assistance of him, and my uncle John and some other relations, I got forty pounds, and a promise of thirty pounds a year, to maintain me at Leyden.
