' Containing an attempt to determine the dates of ancient events from astronomical considerations . . . Newton 

 indicates the manner in which astronomy might be used to verify the views on the chronological points derived in the 

 main from Ptolemy, which were held in his time. These views liave since that date been proved, by the Babylonish and 

 Egyptian records, "to be on the whole correct.'— iJ. T. Glazebrook, F.R.S.

Consisting of two parts, 'de radiorum lucis refractionibus ', and ' de colorum origine '. Only the first part was 

 translated into English. 



' Before the end of 1(369 he had worked out the details of his discovery of the decomposition of a ray of white light into 

 rays of different colours by means of a i)rism. The complete explanation of the theory of the rainbow followed from this 

 discovery. These discoveries formed the subject matter of the lectures which he delivered as Lucasian professor from 

 1(569 to 1671 . . . The MS. of his original lectures was printed in 17:i9 under tlie title Lectiones Optime.'—lV. W. R. Ball.

3250 Another Copy, old calf extra {fine copy), £2. 17* ^d 



This work expounds the corjjuscular or emission theory of light, and first contains his important optical discoveries in 

 a collected form. The above edition also contains two important mathematical treatises left out in the later editions, viz., 

 ' Enumeratio Linearum III. Ordinis ', and ' Tractatus de Quadratura Curvarum ', containing his invention of the 

 ' fluxional ' calculus, and stating in the introduction that he had invented the ' method ' in 1665-6— thus claiiiiirig priority 

 over Leibniz. 



• In this work he dealt in detail with his theory of fits of easy reflexion and transmission, and the colours of thin plates, 

 to which he added an explanation of the colours of thick plates and observations on the inflexion of light,'— IF. W. R. Ball. 



3251 Second [first Octavo] Edition, with Additions, folding plates, Svo. old calf, or, 



boards {rare), 16s 1718 



In this edition the number of queries at the en<l of the work is increased from 16 to 31, including the celebrated one 

 (No. 28) : ' Are not all hypotheses erroneous in whlcli Light is supposed to consist in pression or motion propagated 

 through a fluid medium ? ' . . If it consisted in pression or in motion propagated eitlier in an instant or in time, it would 

 bend into the shadow. For pression and motion cannot be propagated in a fluid in right lines beyond an obstacle which 

 stops part of the motion, but will bend and spread every way in the quiescent medium which lies 1)eyond the shadow.' 

 Query 17 discusses the double refraction of Iceland spar. It also contains a new and interesting preface, mentioning inter 

 alia : ' I do not take gravity for an essential property of bodies." 



3252 Third Edition, corrected, with folding plates, 8vo, hf bound, \2s 1721 



This is a literal reprint of the foregoing edition, save for the addition of one passage in the last sentence in the work

 rebacked (rare), £1. 5* Londini, 1706 



The first Latin Editiok, and the first containing Newton's views on the double refraction of Iceland spar. The

3255 Editio Altera, cui accedunt ejusdem Lectiones Opticae, et Opuscula Omnia ad 



Lucem et Colores pertinentia [interprete Samuele Clarke, d.d.]; with 42 folding jdates, 4to. 

 old calf gilt, \2s Qd Graecii [c. 1740] 



This edition does not include the mathematical writings, but contains the 'Optical Lectures,' and Newton's Memoirs on 

 Light and Colour, contributed to the Philosophical Transactions between 1672 and 1676. 



Newton's ' Optics ' laid the foundation of the emission or ' corpuscular ' theory of light, which was soon succeeded by 

 Huygens's undulatory theory. It contained tlie theory of the rainbow, and an analysis of the colours of thin metallic plates.
