8 BIBLIOGRAPHY OF NEWTON 



pleasant to the eye ... Note that the print will look much better when a book is bound 

 and beaten.' Nothing more seems to have been cone until the 2ist of May, 1709, when 

 Bentley wrote to Professor Roger Cotes that he had arranged with Newton for him to 

 superintend the new edition of the Principia. The correspondence between Newton and 

 Cotes during the printing of the work has been published, edited by Dr. Edleston (see No. 383) 

 from the originals in Trinity College Library. 



Five sheets were printed off by October 2Oth, 1709, but the work was not finished until 

 the first week of March, 1713, when Cotes wished Bentley to write the Preface, but at the 

 request of Newton and Bentley he wrote the Preface himself. On the 25 th of June, 1713, 

 Cotes announced to the author ' that the book is finished. ' In July, Bentley wrote to 

 Newton, ' You will receive by the carrier, according to your order, six copies ; but pray be 

 so free as to command what more you shall want. We have no binders here that either work 

 well or quick, so you must accept them in quires. I gave Roger (Cotes) a dozen ... I 

 have sent (though at great abatement) 200 already to France and Holland. The edition in 

 England^to the last buyer is 15^ in quires, and we shall take care to keep it up for the honour 

 of the book.' 



On the 27th of July, Newton personally presented a copy to the Queen. 



The whole profits of this edition were taken by Bentley. On one occasion Newton 

 wrote to Cotes (Oct. I4th, 1712) concerning the correction of an error which would 'require 

 the reprinting of about a sheet and a half ... I will pay the charge of reprinting it.' In a 

 conversation with Newton, John Conduitt asked him "how he came to let Bentley print his 

 Principia, which he did not understand. * Why,' said he, 'he was covetous, and I let him 

 do it to get money.'" Brewster's Newton, 1855, ! 3 r 4*

Only 12 copies were printed, evidently for presentation. Dr. James Bradley (to 

 whom Newton presented a copy) says ' that they were all originally bound with gilt leaves in 

 red morocco, to a pattern which was much used for the Harleian Library.'
