' Chasles introduced the term anharmonic ratio, corresponding to the German Dopt>dc?rhiiltni* and to Clittbrd's cross 

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

 projected 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-circle ', etc. etc. etc. Prof. Cajori. 



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 the Bibliotheque Natiouale, 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, Caesar, Cleopatra, and St. Jerome ; besides Judas 

 Iscariot, La/arus after his resurrection, and even the A'irgin Mary ; and every one of them written in modern French !
