of the Philosophical Transactions. Nearly 200 passed before Moray's description was confirmed by hydrographic measurements in the Sound of Harris. It was only in 1968 that the phenomenon was satisfactorily explained in terms of the theory of "continental shelf waves". In 1666, Moray published Considerations and Enquiries concerning Tides. There he advocated careful quantitative observation of tidal phenomena and proposed, for the first time in the scientific literature, the use of stilling-wells as tide gauges. Later years Moray became a Privy Councillor again in February 1661, and was later a Lord of the Exchequer. His younger brother, Sir William Moray, was Master of Works to Charles II. The King granted him an apartment at the Palace of Whitehall, where he engaged in chemical experiments. He became a recluse in later life, and, by the time of his death, he was virtually a pauper. He was buried in Westminster Abbey at the order of the King. His grave is unmarked, but his name appears on the stone of Abraham Cowley, near the ashes of Geoffrey Chaucer and Edmund Spenser, in Poets' Corner. Moray had a range of notable friends: James Gregory, Samuel Pepys, Thomas Vaughan, Andrew Marvell, John Evelyn and Gilbert Burnet. Legacy Moray's legacy is just beginning to be appreciated in the country of his birth. In 1969 a masonic lodge of research, Lodge Sir Robert Moray, No.1641, (Edinburgh, Scotland) was established in his honour.
