" We have in this Edition added, in the Margin, References to the English Translation 

 of the Principia lately published, directing to the several Pages in that Translation, where 

 the Things here treated of are proved : And that the Asterisk in the Margin is designed to 

 show how far the Discourse in the Principia is the same with what is found in this Treatise." 

 Note on Half-title. 



The substitution of the extract from the Principia, in place of the long Preface in the 

 first edition, brought the work to conform to the text which was first printed earlier in the 

 same year (see No. 19), whilst additions were made to the translation so as to make the 

 matter agree with the printed text. This points to the fact that the translation was made 

 from a manuscript which slightly varied from the one used in the printing.
