538 Another Copy, containing the folding plate {but one leaf very slightly defective): also, 



H[ooke] (R[obert, f.r.s.]) Attempt for tlie Explication of the Phenomena, observable in 

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

 ing the Aire, in Conlirmation of a former Conjecture, first edition, iv'th folding plate— 2 vols, 

 sm. 8vo. in 1, large and sound copy in mottled calf (very rare), £1. \\s ^d ' ib., 1600-1 



First Edition of the author's first published work, containing his invention of an improved air-immp ('inachin.a 

 Boyleana '), ' presenting all the essential qualities of the modern air-i)unip. By a multitude of experiments performed witli 

 it, Boyle vividly illustrated the effects (at tliat 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 fnqa vacui.'— Agnes M. Gierke. The second tract, treating of capillary attraction, won the attention of 

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

 of his air-pump.

 cr. 4to. old calf {VEF.Y RARE), £1. 155 lb., 1662 



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

 contained experimental i)roof of the, proportional relation between elasticity and pressure, still known as Boyle's Lav: 

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

 ti.'-njed by Mariotte [under whose name it is generally Ivnown on tlie Continent] in 167G.' — Agnes M. Clerke.

 {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 a.s the ' second Engine ' in this work. 



543 Another Copy, with the Second Part, containing divers Experiments made both in 



Compressed and also in Eactitious Air, about Eire, Animals, etc., with Description of the 

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

 broian calf gilt (fine LARGE COPIES) ; RARE, £1. 15* Oxford, ]6Q9— London, '82 



Tlie 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 filtrated through Water, condensed, and rarefietl ; description of a Wind-Gun ; and an 

 Instrument to distill in vacuo,'

' Expounding his principles of a ' mechanical jihilosopliy.' Founded on the old atomic hypothesis, the.'e 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. B.
