' Bergman's chief services to chemistry were in the domain of analysis, which he treated systematically and enriched 



by valuable methods. He knew well how to make his chemical experiences useful for the definition and classification of 



minerals, arid thereby laid the foundation of mineralogical chemistry and chemical geology.' Prof. E. v. Meyer.

6144 [BERKELEY (George, Bp. of Cloyne)} The ANALYST ; or a DISCOURSE addressed to an 

 INFIDEL MATHEMATICIAN, wherein it is examined whether the Object, Principles, and Inferences 

 of the modern Analysis are more distinctly conceived, or more evidently deduced, than Religious 

 Mysteries and Points of Faith ; by the AUTHOR of the MINUTE PHILOSOPHER, first edition, 

 with diagrams, 8vo. sewn (RARE), 12s Qd 1734 



6145 [ ] SECOND EDITION, with diagrams, 8vo. sewn, Is 1754 



'In the Analyst his theological philosophy was further unfolded, jn an argument meant to show that the higher 

 mathematics involve assumptions which as truly exclude definite or exhaustive conceptions as do any of the mysteries of 

 religion.' Prof. Campbell Eraser. 



' Bp. Berkeley argued with great acuteness, contending, among other things, that the fundamental idea of supposing a 

 finite ratio to exist between terms absolutely evanescent was absurd and unintelligible. He was the first to point out what 

 was again shown later by Lazare Carnot, that correct answers were reached by a ' compensation of errors '. Berkeley's 

 attack was not devoid of good results, for it was the immediate cause of the work on fluxions by Maclaurin ' (v. Nos. 2761-3, 

 ante). Prof. Cajori.

' The most permanent result of his enthusiasm was the work published in 1744, ' Siris "... The title ' Siris ' was added 

 in the 2nd edition ; this appeared in 1744, others in 1746 and 1748 . . . The popularity was doubtless due to the medical 

 rattier than to the metaphysical theories which were strongly blended together ; at the time it was the most popular of 

 Berkeley's writings.' Sir Leslie Stephen. 



6147 - Two LETTERS, the one to Thomas Prior, concerning the USEFULNESS of TAR- WATER in 

 the PLAGUE, wherein is considered, whether Tar- Water, prepared with the distilled Acid of Tar, 

 should be preferred to that made in the common Way, by mixing Tar with Water, and stirring 

 them together ; the other to the Rev. Dr. Hales, on the Benefit of TAR- WATER in FEVERS, for 

 Cattle as well as the Human Species, 8vo. (pp. 36), sewn, 6s Qd 1747

' His chief discoveries were the exponential calculus, the treatment of trigonometry as a branch of analysis, the con- 

 ditions for a geodesic, the determination of orthogonal trajectories, the solution of the brachistochrone, the statement that 

 a ray of light traversed such a path that 2/oufc was a minimum, and the enunciation of the principle of virtual work. I 

 believe that he was the first to denote the accelerating effect of gravity by an algebraical sign g, and he thus arrived at the 

 formula v 2 = 2 gh'. W. W. R. Ball.
