JONATHAN, an eminent physician and chemist, and one of the first promoters of the Royal Society, was born about the year 1617. He was elected a fellow of the college of physicians in 1616, and appointed reader of the anatomical lecture in that college in 1647. As he took part against Charles I. accepted the wardenship of Merton-college, Oxford, from Oliver Cromwell when chancellor, and fat sole representative of that university in Cromwell's parliament, he was removed from his wardenship in a manner disgraceful to him by Charles II. He was however then professor of physic at Gresham college, to which he retired, and continued to attend those meetings that gave birth to the Royal Society; upon the first establishment of which he was nominated one of the council. Being fully persuaded that the preparation of medicines was no less the physician's duty than the prescribing them, he constantly prepared his own; and in 1668 published a treatise recommending his example to general practice. He died of an apoplectic fit in 1674; and his memory was preserved by the drops that bore his name, otherwise called Gutter Anglicana, the secret of which he told to Charles II. for 5000l. and which Dr Lifter assures us was only the volatile spirit of raw silk rectified with oil of cinnamon or some other essential oil. But he claims more particular regard, if what Bishop Seth Ward says be true, that he was the first Englishman who made that noble astronomical instrument, the telescope.
