'A work of great merit. Had it been studied more diligently by writers of text-books in England and the United 

 States, many a lax and loose method of analysis hardly as yet eradicated from elementary text-books would have been 

 discarded over half a century ago. Cauchy was the first to publish a rigorous proof of Taylor's theorem. He greatly 

 improved the exposition of fundamental principles of the ditterential calculus by his mode of considering limits and his 

 new theory on the continuity of functions.' -Prof. Cajori.

' Certain hydrodynamical theorems, which he believetl himself to have demonstrated, admitted, in his firm conviction, 

 of application to the observed laws of light, heat, gravity, Juolecular attraction, and electricity. The conclusion pointed 

 to was that the physical forces are mutually related, because all are modes of pressure of the same ethereal medium. The 

 work in which these views were most fully embodied was * Notes on the Principles on Pure and Applied Calculation '.' —

' Chaslos introduced the term (inharmonic ratio, corresponding to the German Doppclverlmltnis and to Clitford's cross 

 ratio ... He gave a reduction, different from Newton's in this, that the line curves from which all others can be pro- 

 .jected are symmetrical with respect to a centre ... To Chasles we owe the introduction into projective geometry of 

 non-projective properties of figures by means of the infinitely distant imaginary .sphero-circ-.le ', etc. etc. etc.— Pro/. Cajori.

' In this reproduction will be found the conceptions of cross ratios and projection— in fact those ideas of modern 

 geometry which Chasles and other writers of this century have used so largely.'— ^T. W. R. Bell. 



The author was the victim of one of the most remarkable and barefacei forgeries ever committed. Starting with the 

 purchase of a spurious correspondence by Pascal, in which the latter claimed all the discoveries made by Newton, the 

 forger, Lucas, a half-educated frequenter ol the Bibliotheque Nationale, was encouraged to the production of the mo.st 

 extraordinary forgeries, which were all bought greedily and in good faith by the simple mathefliatician. They included 

 ' autograph ' letters of Socrates, Aristotle, Alexander the Great, Cicero, Caj-sar, Cleopatra, and St. Jerome ; besides Judas 

 Iscariot, Lazarus after his resurrection, and even the Blessed Virgin Mary ; and every one of them written in modern 

 French !
