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,[2] 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.

Soon after my return from Leyden, I was recommended by my good master,
Mr. Bates, to be surgeon to the "Swallow," Captain Abraham Pannell,
commander; with whom I continued three years and a half, making a voyage
or two into the Levant,[3] and some other parts. When I came back I
resolved to settle in London; to which Mr. Bates, my master, encouraged
me, and by him I was recommended to several patients. I took part of a
small house in the Old Jewry; and, being advised to alter my condition,
I married Mrs. Mary Burton,[4] second daughter to Mr. Edmund Burton,
hosier in Newgate Street, with whom I received four hundred pounds for a
portion.

But my good master, Bates, dying in two years after, and I having few
friends, my business began to fail; for my conscience would not suffer
me to imitate the bad practice of too many among my brethren. Having,
therefore, consulted with my wife, and some of my acquaintance, I
determined to go again to sea. I was surgeon successively in two ships,
and made several voyages, for six years, to the East and West Indies, by
which I got some addition to my fortune. My hours of leisure I spent in
reading the best authors, ancient and modern, being always provided with
a good number of books; and, when I was ashore, in observing the manners
and dispositions of the people, as well as learning their language,
wherein I had a great facility, by the strength of my memory.
