'Newton is the new Archime«les, and the Prindpia 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 gernvs of true scientific procedure which he disclosed in the Prhicipia and Opficks.' —

gold tooling on sides, g. e. , £4. 4.v 



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

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

 important mathematical treatises left out in the later ones, viz., ' Enumeratio Linearum II L Ordinis'. and 'Tractatus de 

 Quadratura Ciirvarum ', containinj; liis invention of the ' fiuxional ' calculus. They were here published for the first time, 

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

 was then just preparing). In his introduction to the Truclatus he states that he had invented the ' method ' in 1G65-G— 

 thus claiming priority over Leibniz. According to the Adverti.iement, ' the ensuing di.'^course was written at the desire 

 of .somt» Gentlemen of the Royal Society, in lt)75. He reveals therein also his peculiarity of shrinking from every kind of 

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

 matters'. 



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

 Letter written to Mr. Leibnitz in 1(570 ... I mentioned a Method by which I had found some general Theorems about 

 8(iuaring curvilinear Figures . . , And some Years ago I lent out a Mai.uscript containing such Theorems, and having 

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

old ccUf (joints cracked), £1. 5s ' [1704] 



The above consists of the optical part only, with a new 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.
