Robinson, Tancred

, a learned physician and botanist, and physician in ordinary to George I. by whom he was knighted, was the very intimate friend of the celebrated Ray, who distinguishes him by the title of amicorum alpha. Of his early history we have not been able to recover many particulars. He was nearly of an age, and ran his course for some time with sir Hans Sloane, with whom, when a student, he travelled to France. He was educated at St. John’s college, Cambridge, where he took his degree of bachelor of medicine in 1679, and that of doctor in 1685. While at Montpellier he wrote a letter to Dr. Martin Lister, dated Aug. 4, 1683, concerning the fabric of the remarkable bridge, called Pont de S. Esprit, on the Rhine, | which was printed in the Philosophical Transactions for June 1684; and, after his return in lhat year, he was elected a fellow of the Royal Society. To this learned body he made various communications, particularly an account of the first four volumes of the “Horius Malabariciis” on the natural sublimation of sulphur from the pyrites and limestone at ^tna, &c. an account of Henry Jenkins, who lived 169 years and on other topics of natural history. The printed correspondence between him and Ray commenced during Dr. Robinson’s travels, before mentioned, and was continued for upwards of ten years. Seventeen of his letters appear in the “Philosophical Correspondence,” with all Mr. Ray’s answers. They run much on the subject of Zoology; but contain also botanical and philosophical observations. These, and what he communicated to the “Philosophical Transactions,” prove him to have been a man well acquainted with various parts of learning to which he added also an intimate knowledge of natural history. In this branch Ray had the highest opinion of him, and placed the greatest confidence in his assistance. He had a seat in the council of the Royal Society for many years. He died March 29, 1748. ¹
