 issue of 171 S. The mathematical tracts were left out in this and the following editions.

 has made additions and corrections (all verified to be in his handwriting), w^hich were wholly 

 or partly adopted in the later editions of the * Opticks '. They are : on page 70, line 20 : - ,-^ is altered

 Precepts of the Noachides were originally the moral Law of all nations ; & the first of them was to have but one supreme 

 Lord God ct not to alienate his worship ; the second was not to profane his name ; & the rest were to abstain from blood 

 or homicide & from fornication (that is from incest adultery & all unlawfuU lusts,) & from theft & all injuries, & to be 

 merciful even to bruit beasts, & to set up magistrates for putting these laws in execution. Whence came the moral 

 Philosophy of the ancient Greeks' (partly adopted in the third Edition, by adding after 'Benefactor': 'as their 

 Ancestors did under the Government of Noah and his Sons before they corrupted themselves '). 



12540 Second Issue of the Second Edition, with 12 folding plates, 8vo. old calf, or, old 



calf, rebacked, 12s 6d W. and J. Innys, 1718 



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

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

 through a fluid medium ? ... If it consisted in pression or in motion propagated either 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 beyond the shadow.' 

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



' At the end of the 3rd book I have added some Questions. And to shew that I do not take Gravity for an essential 

 Property of Bodies, I have added one Question concerning its Cause, chusing to propose it by way of a Question, because 

 I am not yet satisfied about it for want of ^x^rimants.'— Advertisement II. 



12541 Third Edition, corrected, with 12 folding plates, 8vo. old calf, or, old calf, neatly 



rebacked, 12s apud eosdem, 1721 



This is a literal reprint of the foregoing edition, save for a few corrections and the addition of one passage in the last 

 sentence in the work referring to Noah and his sons, as pointed out in the note to Newton's annotated copy of the second 

 edition (No. 12539, supra). 



12542 Fourth [Final] Edition, corrected, with 12 folding plates, 8vo. old calf, or, old calf, 



newly rebacked (rare) , I7s 6d William Innys, 1730 



This was the last edition revised by the Author. 'It was corrected by the Author's own hand, and left before his 

 Death with the Booksejler. ... It has been thought proper to n^a,ke at the bottom of the Pages several Citations from 

 thence [Lectiones Opticael, where may be found the Demonstrations, which the Author omitted in these Opticks'. —

The first Latin Edition, translated by Newton's disciple Dr. Samuel Clarke, afterwards Rector of St. James's, 

 Westminster, whose alleged Arianism gave rise to so long a controversy. It was the first edition to contain Newton's 

 views on the double refraction of Iceland spar, and included six more queries than the English Edition of 1704. It 

 contains for the first time the celebrated one [No. 28] on the nature of light (v. note to No. 12540, supra). The translator 

 received £500. from Newton for his work.
