'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 aud 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 differential calculus by his mode of considering limits and his 

 new theory on the continuity of functions.' -Pro/. Cajori.

1 Certain hydrodynamical theorems, which he believed himself to have demonstrated, admitted, in his firm conviction, 

 of application to the observed laws of light, heat, gravity, molecular 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'.'

'Chasies introduced the term anharmonic ratio, corresponding to the German Doppclverhaltnis and to Clifford'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 Chasies we owe the introduction into projective geometry of 

 iion-projective properties of figures by means of the infinitely distant imaginary sphere-circle ', etc. etc. etc. Prof. Cajori.

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

 geometry which Chasies arid other writers of this century have used so largely.' W. W. R. Bell. 



The author was the victim of one of the most remarkable and barefaced 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 of fhe Bibliotheque Nationale, was encouraged to the production of the most 

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

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

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