LONG, ROGER, was born in the county of Norfolk about the year 1680. At the age of seventeen he entered Pembroke Hall, Cambridge, took the degres of Master of Arts in 1704, and that of Doctor of Divinity in 1728, The followitig year he was elected a Fellow of the Royal Society and Vice-Chancellor of the University; in 1749 he was appointed Lowndes'a Professor of Astronomy, and in 1751 he was presented to the rectory of Bradwcll in Essex, which he held until his death, December 16, 1770. His principal work is a treatise ou astronomy, in two large quarto volumes, the first of which was pub lished in 1742, the other in 1764: a second edition appeared in 1784. This work centains very good descriptions of the apparent motions of the heavens. Besides his astronomy he wrote, under the signature of Dicaiophilus Cantabrigiensis,' a pamphlet eutitled The Rights of Churches and Colleges defended,' 1731 ; Reply to Dr. Gally's Pamphlet on Greek Accent,' 1755 ; Life of Mehemet,' prefixed to Oakley's ' History of the Sarneens,' 1757; 'Music Speech spoken at the Public Commencement, July 6, 1714,' and other poems, London, 1719, to which ie prefixed a short notice of the authors life. With a
view to popularise the science of astronomy, he caused to be con structed a hollow sphere, wherein thirty persons could sit conveniently, and on the inner surface of which was a representation of the heavens as they would appear to an observer in north latitude. The keeper of this sphere, who is generally an undergraduate, receives GI. per annum. The habits of Dr. Long were peculiarly moderate, his ordinary drink being water ; and for some years previous to his death he abstained altogether from eating animal food. By his will he bequeathed 6001. for the benefit of his college. (Biog. Brie,; Memoir of Dr. Wood meutioned above.)
