 of Durham University. The above translation includes Newton's Prefaces, and Cotes's to the second Edition, and an 

 Introduction (pp. 18) by himself. 



'Newton is the new Archimedes, and the Principia forms the Novum Organum of scientific method. . . . There is 

 hardly a progressive branch of physical and mathematical science, excepting perhaps chemistry and electricity, which has- 

 not been developed from the germs of true scientific procedure which he disclosed in the Principia and Optlclcs.' 

 Prof. W. S. Jevons, F.R.S.

The above work is one of the great classics of optics. It expounds Newton's corpuscular or emission theory of light, 

 and first contains his important optical discoveries in a collected form. The above first edition also contains two 

 important mathematical treatises left out in the later ones, vis., ' Enumcratio Linearum II [. Ordinis', and 'Tractatus de 

 Quadratura Curvarum ', containing his invention of the ' fluxional ' calculus. They were here published for the first time, 

 especially with a view to assert Newton's rights to the discovery of the calculus (of which the controversy with Leibniz 

 was then just preparing). In his introduction to the Tractatus he states that he had invented the 'method' in 1665-6 

 thus claiming priority over Leibniz. According to the Advertisement, the ensuing discourse was written at the desire 

 of som* Gentlemen of the Royal Society, in 1(575. He reveals therein also his peculiarity of shrinking from every kind of 

 publicity, when he complains that he had delayed the printing 'to avoid being engaged in disputes about these 

 matters '. 



The last passage of the Advertisement is of importance in connexion with the Newton-Leibniz controversy : ' In a 

 Letter written to Mr. Leibnitz in 1676 ... I mentioned a Method by which I had found some general Theorems about 

 squaring curvilinear Figures . . . And some Years ago I lent out a Manuscript containing such Theorems, and having 

 since met with some Things copied out of it, I have on this Occasion made it publick '.

The above consists of the optical part only, with a neAv title, without date, place, or printer's name, but giving the 

 author's name. This issue seems to be rare, no mention being made of it in bibliographies.
