(Dr John), an eminent physician and astronomer, born at Ashby de la Zouche in Leicestershire, in 1582. He taught a grammar school for some years, and practiced physic, employing his leisure hours hours in astronomy, which was his favourite study: at length he removed to London, was admitted a fellow of the college of physicians, and raised his character by his description of the comet in 1618. The next year Sir Henry Savile appointed him his first professor of astronomy at Oxford; and the masters and fellows of Merton-college made him first junior, and then superior, reader of Linacre's lecture. He died in 1643, having written many works, some of which have never been published: but the MSS. are preserved in the library of Trinity-college, Dublin.
