Collation : Title, Dedication to the Royal Society, Prsefatio ad Lectorem 

 (signed Is. Newton), Halley's verses : ' In viri prsestantissimi D. 

 Isaaci Newtoni opus hocce mathematico-physicum Saculi Gentisquc 

 nostrae Decus egregium* (signed Edm. Halley), 4 11. -f- pp. [i] [383], 

 [400] [510], -f i 1. blank, -f- Errata, i 1. Sigs. A Zz, # %, Aaa 

 Ooo 4 , i If. (errata). The leaf of Errata is sometimes bound after 

 Halley's verses, i folding plate at p. 496 or after Halley's verses. 



The guards to pp. 1056 and 11112 are left in some copies. This is explained in 

 Halley's letter to Newton, 14 March, i68f , ' if they [the mistakes] be very material, the 

 sheet shall be done over again, as I was forced to do the sheet D, and half the sheet P must 

 be done, for the figure is turned upside down by ye negligence of the printer in p. 112.' It 

 is also worth noting that the catchword at the bottom of p. 1 12 is 'tivi,' but 'tive' com- 

 mences the next page. 



Reissued afterwards with a new title-page, containing a different 

 imprint :
