George Castle

son of John Castle sometimes Doctor of Physick of this University, was born in the County of Middlesex, in London as it seems, educated partly in Grammar learning in the Free-school at Thame in Oxfordshire while Dr. Will. Burt was the Master, admitted a Communer of Ball. Coll. 8. Apr. 1652, aged 17 years or thereabouts, elected Probationer Fellow of Alls. Coll. in 1655, being then Bach. of Arts. Afterwards proceeding in that faculty, he applied his Studies to Medicine with the help of his Fathers notes, took the degrees in that faculty, that of Doctor being compleated in the year 1665, being about that time a member of the Royal Society, and a Candidate, as it seems, of the Coll. of Physitians. He hath written,

The Chymical Galenist: A treatise wherein the practice of the Ancients is reconciled to the new discoveries in the Theory of Physick, &c. Lond. 1667. oct.

Reflections on a book intit. Medela Medicinae.—Printed with the former book. Afterwards by the favour of his intimate and dear friend Martin Clifford Master of Suttons Hospital alias the Charter-house, he became Physitian there and practised his faculty with good success: But giving himself the liberty of too frequent indulgments, either to please his friend, or patient, or both, was taken away by death in the prime of his years on the twelfth day of Octob. (or thereabouts) in sixteen hundred seventy and three,1673. and was, I suppose, buried in the Chap. belonging to the said Hospital. By the way I must tell you that the said Mart. Clifford had been educated in Westminster School, and thence elected into Trin. Coll. in Cambridge an. 1640, where he arrived to good learning, and might have been eminent had not the Wars hindred his progress. He was the author of A treatise of humane reason, Lond. 1675 in 4. sh. in tw. Which book being made publick in Aug. 1674, it hapned that Dr. B. Laney Bishop of Ely dined with many persons of quality in Octob. following in the Charterhouse; and whether he then knew that Mart. Clifford the Master was author of it, is uncertain. However he being then asked what he thought of that book, answer’d that ’twas no matter if all the copies were burnt and the author with them, knowing by what he had read in the book that the author makes every mans private fancy, judge of religion, which the Rom. Catholicks have for these 100 years cast upon protestantisme. In Decemb. following were published Observations upon a treat. intit. Of hum. reason. Lond. 1675. in 3. sh. in tw. commonly reported then to be written by the same hand, and soon after another thing intit. Plain dealing: or, a full and particular examination of a late treatise intit. Humane reason. Lond. 1675 in 7. sh. in tw. said in the title to be written by A. M. a Country Gentleman. Whereupon came out a reply called An Apology for the discourse of humane reason, &c. Lond. 1680, in 7. sh. in tw. with a Review of, and an appendix to, it, written by Alb. Warren, who, at the end of all, hath added Cliffords Epitaph, and just character, to which I refer the reader. This Mr. Clifford died on the 10. of Decemb. or thereabouts, an. 1677 and was buried in the Chap. belonging to Suttons Hospital. Soon after was elected into his place of Master of that Hospital William Erskyne Esq. a member of the Royal Society, Cupbearer to his Majesty and a younger Son of John Earl of Marr.
