 Effects (made, for the most part, in a NEW PNEUMATICAL ENGINE), first edition, 12mo. old calf

538 - - ANOTHER COPY, containing the folding plate (but one leaf very slightly defective)-, also, 

 H[ooke] (R[obert, F.R.S.]) ATTEMPT for the EXPLICATION of the PHENOMENA, observable in 

 an Experiment published by It. B., in the XXXV. EXPERIMENT of his Epistolical Discourse touch- 

 ing the AlRE, in Continuation of a former Conjecture, first edition, iv ; th folding plate 2 vols. 

 sni. 8vo. in 1, large and sound copy in mottled calf (VERY RARE), 1. 11s Qd ib., 1660-1 



FIRST EDITION OF THE AUTHOR'S FIRST PUBLISHED WORK, containing his invention of an improved air-pump ('machina, 

 Boyleana '), ' presenting all the essential qualities of the modern air-pump. By a multitude of experiments performed with 

 it, Boyle vividly illustrated the effects (at that time very imperfectly recognised) of the elasticity, compressibility, and 

 weight of the air; investigated its function in respiration, combustion, and conveyance of sound, and exploded the 

 obscure notion of a futja vacui.' Agnes M. Clerke. The second tract, treating of capillary attraction, won the attention of 

 the Royal Society. Its author, Robert Hooke, was then assistant to Boyle, and aided him materially in the construction 

 of his air-pump. 



539 _ _ ANOTHER COPY of the 'NEW EXPERIMENTS', first edition, with fold ing plate, Oxford, 

 1660: EXPERIMENTS and CONSIDERATIONS about the POROSITY of BODIES, first edition, '84 

 2 vols. sm. 8vo. in ], large sound copies in contemporary calf, 1. 15s ib., 1660-84

 Experiments, against the OBJECTIONS of FRANCISCUS LINUS, and THOMAS ROEKES, folding plate, 

 cr. 4to. old calf (VERY RARE), 1. 155 ib., 1662 



This edition is of great importance, as first containing what is now known as Boyle's Law. ' The ' Defence against Linus ' 

 contained experimental proof of the, proportional relation between elasticity and pressure, still known as /,VH//*-'.V l.nn-. 

 This approximately true principle, although loosely demonstrated, was at once generalised and accepted, and was con- 

 lirmcd by MARIOTTE [under whose name it is generally known on the Continent] in 1676.' Agnes M. Clerke. 



541 - THIRD EDITION, with the DEFENCE against the Objections of FRANCISCUS LINUS and 

 THOMAS HOBBS, cr. 4to., new hf. brown calf extra (title stamped, 2 holes in if, and jiJatc

 CONSISTENT BODIES, first edition, with 8 folding plates on copper, cr. 4to. contemporary calf 

 (title and a few II. stained, otherwise a sound and large copy) ; RARE, 16* Qd Oxford, H. Hall, 1669 



Specially valuable for giving a description of his air-pump as improved by ROBERT HOOKE, the author's assistant, 

 spoken of as the ' second Engine ' in this work. 



543 - ANOTHER COPY, with the Second Part, containing divers EXPERIMENTS made both in 

 COMPRESSED and also in FACTITIOUS AIR, about Fire, Animals, etc., with DESCRIPTION of the 

 ENGINES wherein they were made, 5 copperplates 2 vols. cr. 4to. in 1, first editions; new hf. 

 brown calf gilt (FINE LARGE COPIES) ; RARE, 1. 15s Oxford, 1669 London, '82 



The illustrations of the second part contain ' an Engine, with a double Tube for the exhausting of the Air ; a Mercurial 

 Gage; an Engine to compress the Air; how factitious Air may be transmitted out of one Receiver into another; an 

 Instrument by which Air may be nitrated through Water, condensed, and rareh'ed ; description of a Wind-Gun ; and an 

 Instrument to distill in vacuo.' 



544 - NOVA EXPERIMENTA PHYSICO-MECHANICA de Vl AERis ELASTICA, et ejusdeni Effectibus, 

 facta maximam partem in NOVA MACHINA PNEUMATICA ; first Latin edition (wanting plate), 

 Oxonice, H. Hall, '61 : ATTEMPT for the EXPLICATION of the PHENOMENA, observable in an

 Nitre), first edition, 12mo. FINE COPY in old caJ/(RAHE), 1. 5s Oxford, 16C6 



' Expounding his principles of a ' mechanical philosophy.' Founded on the old atomic hypothesis. these accord in the 

 main with the views of many recent physicists. They postulate one universal kind of matter, admit in the construction 

 of the visible world only moving atoms, and derive diversity of substance from their various modes of grouping and 

 manner of movement.' D. N. Ji. 



547 [ ] PROEMIAL ESSAY, whereir;, with some considerations touching EXPERIMENTAL ESSAYS in 



GENERAL, is interwoven such an Introduction to all those written by the Author, as is necessary
