MY father had a small estate in Nottinghamshire; I was the third of five sons. He sent me to Emanuel 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: there I studied physic two years and seven months, knowing it would be useful in long voyages.
