'Adrianus Romanus and Ludolph van Cetilcn occupied themselves with approximating to the ratio between the 

 circumference and the diameter [of the circle]. The former carried the value IT to 15, the latter to 35, places. The value 

 of IT is therefore often named Ltidolph's number. His performance was considered so extraordinary, that the numbers 

 were cut on his tomb-stone in St. Peter's church-yard at Leyden.' Prof. Cajori.

 Mathematical Principles to Theories of Physical Forces, plate, thick 8vo. cl. (out of print), 8s Qd 



ib., 1869 



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

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

 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 '.'

' Chasles introduced the term anfiarnwnic ratio, corresponding to the German Doppelcerluiltn is and to Clifford's cross 

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

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

 non-projcctive properties of figures by means of the infinitely distant imaginary? phero-cirele', etc. etc. etc. Prof. CfjorL
