'Iii reality the first treatise dealing with the calculus of finite differences. It contained the celebrated formula known 

 laylor 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 baffled 

 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 diecuseid the form of the catenaiy and the determination of the centres 

 of osculation and percussion '. D. N. B.
