 from the Seine. There is no exact description of the engine proposed by Morland, but the project is of the highest interest as one of the first to demonstrate the practical utility of steam-power. Morland's experiments must have been conducted with great care and skill, his estimate that at the temperature of boiling water steam was about two thousand times more bulky than water being substantially confirmed by Watt after careful investigation some hundred years later (cf. paper by Mr. in Transactions of the Institute of Civil Engineers, January 1884;, Life of Watt, 2nd ed. p. 76 ; , History of the Steam Engine, 1831, p. 26 ; , Steam Engine, pp. 108, 141 : and cf. art. , second ). From one of the several medals that were struck in Morland's honour and are now preserved in the British Museum, it would appear that he had also seriously considered the possibility of employing steam as a prime mover in the propulsion of vessels. The medal in question represents a conical-shaped vessel on a square wooden base, floating upon the sea. In the side is inserted a long pipe or arm, and from the top issues steam. In the distance is a ship in full sail, and the legend is 'Concordes. ignibvs. undæ.' (, Medallic Illust. p. 596; and art. {sc|Hulls, Jonathan}}).

Morland's other works are: 1. 'A New Method of Criptography,' 1666, fol. 2. 'Four Diagrams of Fortifications ' [1670 ?], fol. ; attributed to him in the British Museum Catalogue. 3. 'The Count of Pagan's Method of delineating all manner of Fortifications from the exterior Polygone, reduced to English measure, and converted into Hereotectonick Lines,' London, 1672. 4. 'A new and most useful Instrument for Addition and Subtraction, &c., with a perpetual Almanack,' London, 1672, 8vo. 5. 'The Doctrine of Interest, both simple and compound, explained. . . discovering the errors of the ordinary Tables of Rebate for Annuities, at simple interest, and containing tables for the interest and rebate of money,' London, 1679, 8vo. 6. 'The Poor Man's Dyal, with an Instrument to set it. Made applicable to any place in England, Scotland, Ireland, &c.,' London, 1689, 4to, pp. 5. This tract, giving directions for the construction of a simple sun-dial, was reprinted in facsimile by Mr. Richard B. Prosser [London, 1886], 4to, from a copy, probably unique, in the library at Lambeth. 7. ' Hydrostatics, or Instructions concerning Water-works,' London, 1697, 12mo ; a posthumous work, edited by his son, Joseph Morland, and containing an account of various methods of raising-water and tables of square and cube roots. It appears from the preface that a number of mathematical papers, left by Morland, were then in his son's possession.

Besides Lely's portrait mentioned above, there is a portrait in a wig prefixed to the 'Description and Use of two Arithmetical Instruments,' and a portrait after a drawing in the Pepysian collection is reproduced in the third volume of Mr. Wheatley's edition of 'Pepys's Diary.'' A miniature of Morland belonged to Bennet Woodcroft of the Patent Office.  MORLEY,. [See, 1772-1840.]

MORLEY,. [See, 1476-1556.]

MORLEY, CHRISTOPHER LOVE (fl. 1700), physician, was born in or about 1646, and from his name may probably have been related to Christopher Love [q. v.] the presbyterian. He was entered as a medical student at Leyden 18 Feb. 1676 (English Students at Leyden, Index Society, 1883), being then thirty years of age, and graduated M.D. in 1679. According to a short account of Morley in the preface to his 'Collectanea Chymica,' he had travelled widely, and apparently practised medicine before coming to Holland. At Leyden he attended the medical practice of Schacht and Drelincourt, with the anatomical lectures of the latter, and also studied chemistry with Maëts and others. Morley was accustomed to take copious notes of lectures, cases, &c.,
