This second French edition is greatly superior to the first Amsterdam edition of 1720 (which was published in 12mo.) not only textually but for its beauty. According to Guerlac, it is the handsomest edition of the Opticks printed in Newton’s lifetime, or indeed later. This edition, quite rare, was edited by Pierre Varignon, and included changes proposed by de Moivre and authorized by Newton.
