He was sent to Utrecht, where he studied for three years under Grmvius ; having decided to follow the medical profession, lie then went to Leyden and attended the lectures of Hermann and Pitcairn. In 1695 he graduated in philosophy and physic at Padua' and in the following year lie returned to his native place, entering at once on a successful practice.
