279 BARLOW (William) NEW THEORIES of MATTER and FORCE, ill., 8vo. d ., 5s (p. 12.?) 1885 



The author's observations are based on a new theory of the ether, 'according to which the transmission of wave 

 motions depe.ids on the mutual repulsions of similarly electrified particles.'

FIRST EDITIONS of the author's two chief mathematical works. 'In the Optical Lectures many problems connected 

 with the reflexion and refraction of light are treated with ingenuity. The geometrical to? us of a point seen by reflexion or 

 refraction is defined ; and it is explained that the image of an object is the locus of the geometrical foci of every point on 

 it. Barrow also worked out a few of the easier properties of thin lenses; and considerably simplified the Cartesian 

 explanation of the rainbow. The geometrical lectures contain some new ways of determining the areas and tangents of 

 curves. The most celebrated of these is the method given for the determination of tangents to curves '.IF. W. R. Hall. 

 According to the preface NEWTON revised and corrected the work and adde I matter of his own.

 Lectures ; with his Oratorical Preface, at Cambridge, trans, by JOHN KIRKBY, pr., with fine 

 engraved portrait, Svo. old panelled calf ', 8s Qd 1731 



'As a mathematician he was considered by his contemporaries as second only to Newton'. Canon Ovcrton. 'The 

 principal part which Barrow plays in mathematical history is as one of the immediate precursors of Newton and Leibnitz 

 in the invention of the differential calculus'. Dr. Whewell.

Hamburg, 1700 



The third German edition of the author's complete works. 'He regarded salt, sulphur, and mercury, as the three 

 bodies contained i'l the metals, and inferred that the philosopher's stone must be a sort of combination a compound, 

 namely, of salt, sulphur, and mercury ; so pure that its projection on the baser metals should be able to work them up 

 into greater and greater purity, bringing them at last to the state of silver and gold. His practical knowledge was great ; 

 lie knew how to precipitate iron from solution by potash, and was acquainted with many similar processes, so that he is 

 ranked as the founder of analytical chemistry.'

'He shows how to prepare antimony itself from the native sulphide . . . He gives distinct recipes for the preparation 

 of antimony trichloride, of powder of algaroth (basic chloride of antimony), of antimony trioxide, and of potassie 

 antimoniate. and there can hardly be a doubt that he recommended and applied those preparations for internal use.'

 partly collected, and partly of the Authors Peculiar Practice, and Invention, first edition, with 

 finely engraved title in compartments, and very numerous curious and ivell-executed woodcuts (some 

 full-page), sm. 4to. contemporary calf (some II. stained, a few headlines shorn, and the divisional

The first edition of this curious work is EXCESSIVELY BARE, no copy having happened for sale for the last 20 years. Some 

 of the experiments described and depicted are very curious, including instructions how to make Weather-glasses ; 

 Water-clocks, etc , Experiments of ' drawing Avater by the Crane, and by Engins, of forcing water by ayre compressed and 

 by Engins, of producing sounds by ayre and water, by etaporarion of water by lire, and by Engins, of motions by 

 evaporating water, and by rarifying ayrc,' etc. etc. etc. Bearing in mind the early date of publication, its descriptions of 

 engines driven by steam are of considerable interest. There is no copy of this edition in the British Museum, nor is the 

 author noticed in D. N. Ji. 



Page 155 describes how to make a FREEZING MIXTURE, which is of special interest, ROBERT BOYLE having been 

 credited with making the first experiments in 1667 thirty-three years after the publication of the above work.
