&quot; I have re-examined the memoirs of the great geometers, and have striven 

 to consolidate their latest researches and their most exalted forms of thought 

 into a consistent and uniform treatise. If I have hereby succeeded in open 

 ing to the students of my country a readier access to these choice jewels of 

 intellect ; if their brilliancy is not impaired in this attempt to reset them ; if,

 a stronger light upon the names of their discoverers , and, still more, if any 

 gem which I may have presumed to add is not wholly lustreless in the collec 

 tion, I shall feel that my work has not been in vain.&quot; Extract from the Pre
