(John), an eminent English mathematician, was born at Oundle in Northamptonshire, 1622. After a proper foundation at school, he was sent to Oxford, where he was entered a commoner of St Edmund's Hall in 1637. He took the degree of bachelor of arts in 1641; and the year following was created master, among several gentlemen that belonged to the king and court, then residing in the university. At which time, his genius being inclined to astronomy and the mathematics, he applied himself diligently to those sciences, and made a great proficiency in them, which he found of service during the times of the usurpation. After the restoration of Charles II., he reaped the fruits of his loyalty; being created doctor of divinity at Oxford Sept. 1661, he was made one of the king's chaplains, and rector of Roos in Herefordshire, in the place of Mr John Toombes, ejected for nonconformity. He held this living till his death, which happened at Roos on Christmas-day 1678. Mr Wood gives him the character of a capricious and humourous person; however that may be, his writings are sufficient monuments of his genius and skill in the mathematics. These are,
