' A work which produced a great change for the better in the Cambridge matheinatical books. It is the first in which 

 constant use is made of the method known by the name of the spparation of the symbols of operation, and the author has 

 enlivened its pages by occasionally introducing historical notices of the problems discussed.' D. N. B.

'Showing how the areas of the circle and'hyperbola could be obtained in the form of infinite convergent series, and here 

 (I believe for the first time) we find a distinction drawn between convergent and divergent series. It contains a remark- 

 able geometrical proposition to the effect that the ratio of the area of any arbitrary sector of a circle to that of the 

 inscribed or circumscribed regular polygons is not expressible by a finite number of algebraical terms. Hence he inferred 

 that the quadrature of a circle was impossible'. W. W. R. Ball. 



This edition first contains the Geometriie Pars, in which the author explains how the volumes of solids of revolution can 

 be determined.
