107), and in 1654 settled in London, and on 22 December was admitted a candidate of the College of Physicians, and on 20 October 1664 was elected a fellow.
His first work, published in London in 1654, was an edition of Foster's ‘Four Treatises of Dialing,’ and in 1659 he published the residue of Foster's papers, with some mathematical essays of his own, in a folio volume entitled ‘Miscellanies or Mathematical Lucubrations.’ He published in 1666 ‘Medicina veterum Vindicata, or an Answer to a book entitled Medela Medicinæ,’ a defence of the orthodox medical doctrines of the day against Marchamont Needham.
The book, which is dedicated to Lord-chancellor Clarendon, and to the chiefs of the three courts, Keeling, Bridgman, and Hales, shows a good deal of general learning and much power of argument, while many passages illustrate the author's taste for mathematics, but it contains no clinical or pathological observations.
In the same year he published another book of the same kind, an ‘Answer to Medicina Instaurata’ (London, 8vo).
He continued his mathematical studies, and published in 1685 ‘The Use of the Great Planisphere called the Analemma.’ He died unmarried on 13 September 1688.
