12155 MOBLAND (Sir Samuel) The Description and Use of Two Arithmetick Instruments, 

 together with a Short Treatise, explaining and demonstrating the Ordinary Operations of 

 Arithmetick, as likewise a Perpetual Almanack, and several Useful Tables, v-ith 13 copper- 

 plates {4 folding), 10 tables on copper, and diagrams, 16mo. contemporary calf {joints ireak) ; 

 RARE, £2. 7« 6d Moses Pitt, at the White-Hart in Little- Britain, 1673 



12156 Another Copy, w>i7A the rare engraved portrait *in a wig'-, fine and large 



copy in contemporary calf gilt (hack slightly damaged), £3. 36^ 



The above work includes, with a separate title, dated ItJTJ : ' A New and most useful lustruincnt for Addition and 

 Snbstraction of Pounds, Shillings, Pence, and Farthings, without charging the Memory, disturbina; the Mind, or exposing 

 the Operator to any Uncertainty : which no Method heretofore published, can justly pretend to. Invented and presented 

 to . . . Charles II. 1(3(36 by S. Morland '. 



' The arithmetical machines, originally presented to Charles 11. in 1602 [sic], were manufactured for sale by Humphry 

 Adanson, who lived with Jonas >»oore in the Tower of London. By means of them the lour fundamental rules of 

 arithmetic were readily worked. This calculating machine apjiears to have been a modification of one constructed by 

 JJlaise Pascal about 1(542. One of Morland's machines [which were the prototype of Thomas's arithmometerj is now at 

 South Kensington '.— 7>. A^ B.

bound in old English crimson morocco extra, gilt backs, Harleian gold tooling on sides,

This copy is from the library of George Rennie, c.e., f.r.s., and belonged originally to William Ludlam. pr., 

 mathematician (1717-88), who has written on the flyleaf an account of the author's water engine at Windsor, which ' raised 

 water from the Thames (30 feet above the top of Windsor Castle at the rate of 60 barrels per hour by eight men ' (/>. A'. £.). 



ThA above is a very rare, if not unique, ifsuf, not only from having a portrait added, but also for having, in place of thf^ 

 ' Almanac Perpetuel ' usually occurring, a ' Table des Pieds Quarrez et Pieds Cubiques '. 



Tliis is the author's most important work (no English edition of which has ever been published), and includes his 

 invention of the j)lvngerp^imp, conUiinms the gland and stulling box— a contrivance often erroneously attributed to 

 .lames Watt. The appendix contains ' Reflexions tres-curieuscs sur la Proportion Continue", 'Table pour la Quadrature 

 du Ccrcle', and Huit Problemes de Mechanique proposezaux plus habiles Machinistes du Siccle'. 



' Morland was one of the chief mechanicians of his time. His most important discoveries were in connexion with 

 hydrostatics. The problems connected with raising water to a height by mechanical means were receiving a great 

 amount of attention during the middle of the XVII. century, and to the discoveries in this field (in which Morland bore an 

 important part) are largely attributed the subsequent rapid development of the steam-engine and the accelerated rate of 

 evolution in mechanical science generally.'— K. N. B. 



In the original MS. of the alx)ve work (preserved in the British Museum) the author made an important suggestion for 

 employing steam for working pumps, which made him one of the first to demonstrate the practical utility of steam-power. 



' The plunger immp was invented by Sir Samuel Morland, and patented by him in 1675. The best feature in Sir 

 Samuel's invention is the stutting-box. This last-named contrivance, whose universal utility is testified by its very 

 general use, and without which the steam engine could scarcely exist, is undoubtedly the invention of this distinguished 

 and ingenious man, and alone ought to render his name immortal '.— WHliniii Pole, F.R .S. 



12159 Hydrostaticks : or, INSTRUCTIONS concerning Water Works collected out of the 



Papers of Sir Samuel Morland [with Preface by his Son Joseph Morland], containing the 

 Method which he made Use of in this Curious Art, with 5 woodcuts, 16nio. co7itemporary sheep 

 (rare), £1. 55 John Lawrence, 1697 



'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 hip son's possession.' — D. N. B. 



'Retold me particularly that they [the papers printed in the above work] contained the Mystery of that Art and 

 nimble Dispatch, which he was .Master of in the Making and Managing of (more especially) such Mechanical Engines as 

 relate to the Water '.—/'/ e/f^r.

 graphic Map of the True Course of Encke's Comet, with a Letter to the Members of the 

 Royal Astronomical Society, with 2 folding plates, 8vo. (pp. 45), sewn, 6s 6d [1860] 



This paradox (which is not budgeted by Prof, de Morgan) attempts to explain the course of comets in agreement with 

 the author's geocentric system. 



'Zadkiel Tao Sze' as a Lieutenant in the Navy seems queer nowa<lays, but such he was before he took up with 

 astrology. Whether he was a fool or a charlatan can never be proved ; but he showed much bravery on active service 

 before he was twenty, and was equally brave in saving life afterwards. He became a stubborn paradoxer as well as the 

 most popular prophetaster of his time.
