'He introduced into analytic geometry the methodic use of the equation of a line. He made important contributions 

 to surfaces of the second degree, and discovered between the theory of surfaces and the integration of partial differential 

 equations, a hidden relation which threw new light upon both subjects. He gave the differential of curves of curvature 

 and applied it to the ellipsoid,' etc. etc.— Prof. Capri.
