• In reality the first treatise dealing with the calculus of finite diflferences. It contained the celebrated formuU known 

 as ' Taylor's theorem '. The importance of the discovery was not fully recognised, however, until it was pointed out by 

 Lagrange in 1772. In this work Taylor also applied the calculus for the solution of several problems which had bftffled 

 previous investigators. For the first time he determined the differential equation of the path of a ray of light when 

 traversing a heterogeneous medium. He also discussed the foim of the catenary and the detennination of the centres 

 of oscillation and percussion '.—D. N. B.
