 further tested by trials of the Greyhound and Perseus off Plymouth. At the suggestion of Edward James Reed, he proposed to the admiralty to conduct a series of experiments on the resistance of models. This offer was accepted in 1870, and from that time he devoted his energies to the conducting of experiments for the government on the resistance of ships, and on the cognate subject of their propulsion. The admiralty establishment at Torquay erected for carrying out these experiments contained a covered tank, 250 feet long, 33 feet wide, and 10 feet deep. Above the tank was suspended a railway, on which ran a truck drawn at any given speed, and beneath this truck the model was drawn through the water, and its resistance was measured by a self-acting dynamometer on the truck. His researches into the expenditure of power in screw-ships, the proportions of screw-propellers, and the information to be deduced from the speed-trials of ships, have been of immense importance to the royal navy and to the mercantile marine. His value as an adviser was recognised by his appointment as a member of the committee on design in 1870, and on the Inflexible committee in 1877, and by the confidence afforded to him by the successive heads of the admiralty. He became a member of the Institution of Civil Engineers 7 April 1846, and in 1877 was named a member of the council. On 2 June 1870 he was elected a fellow of the Royal Society, and on 27 April 1876 he received the degree of LL.D. from the university of Glasgow. In the same year he was given the royal medal of the Royal Society. He gave evidence before the royal commission on scientific research 29 May 1872, which contains details of the experiments which he undertook for the admiralty (Report of Royal Commission, 1874, ii. 147–52, in Parliamentary Papers, 1874, vol. xxiii.) His last work was the construction of a dynamometer capable of determining the power of large marine engines. This machine, which he did not live to see experimented on, was afterwards tried with complete success. In the winter of 1878 he went on a cruise to the Cape of Good Hope in H.M.S. Boadicea, and was about to return to England when he was seized with an attack of dysentery, and died at Admiralty House, Simon's Town, on 4 May 1879, and was buried in the Naval cemetery on 12 May. He was the author of papers in ‘Minutes of Proceedings of Institution of Civil Engineers,’ ‘Journal of Bath and West of England Society,’ ‘Proceedings of Institution of Mechanical Engineers,’ ‘Transactions of the Institution of Naval Architects,’ ‘Reports of the British Association,’ ‘Naval Science,’ ‘Nature,’ and other publications, most of them referring to his experiments in connection with ships.

FROWDE, PHILIP (d. 1738), poet, was the son of Philip Frowde, deputy postmaster-general from 1678 to 1688 (, Book of Dignities, p. 198). His grandfather, Colonel Philip Frowde, for his faithful adherence to Charles I and Charles II was knighted on 10 March 1664–5 (, Knights, Harl. Soc., p. 190), and appointed governor of the post office (Cal. State Papers, Dom. 1660–1667; London Daily Post, 28 Dec. 1738). From Eton, where young Philip was contemporary with Walpole (dedication to The Fall of Saguntum), Frowde passed to Magdalen College, Oxford, as a gentleman-commoner, and became one of Addison's pupils (A. B., The History of Saguntum, p. 51). He did not take a degree. To vol. ii. of ‘Musarum Anglicanarum Analecta,’ 8vo, Oxford, 1699, edited by Addison, Frowde contributed (pp. 145–7) ‘Cursus Glacialis, Anglicè, Scating.’ In May 1720 Curll published these justly admired verses as Addison's, together with an English version also supposed to be Addison's, and an impudent preface by one T. N., who states that although Addison was well known to be the author, he had always allowed Frowde to pass them as his own. An anonymous imitation in English appeared in 1774; there is also a translation in ‘Miscellanea,’ by J[ames] G[lassford], 4to, Edinburgh, 1818 (pp. 24–9). Frowde wrote likewise a frosty blank verse tragedy entitled ‘The Fall of Saguntum,’ 8vo, London, 1727, in which the influence of ‘Cato’ is clearly perceptible. It was acted at Lincoln's Inn Fields on 16 Jan. 1726–7 (, Hist. of the Stage, iii. 191–192), Quin representing Eurydamas and delivering the prologue by Theobald. The tragedy obtained only about three representations, and is chiefly remarkable for an exquisitely absurd dedication to Sir Robert Walpole, who is described as ‘bringing the learning and arts of Greece and Rome into the cabinet; either that to instruct in the depths of reasoning; or these in the rules of governing.’ Previously to its performance an enthusiastic friend, A. B., possibly Frowde himself, undertook to explain for the benefit of ‘a lady of quality’ the numerous histori-
