Part II. (1883), General Science, 155. A reduction on these prices is 

 made to Fellows. A List of Additions to the Library made during 

 the year will be found in the Year Book. 



The Regulations for the use of the Library are governed by 

 Statutes, Chap. XIV., 7-11 (see Year Book); and are embodied 

 in rules which are printed in the Year Book. The books lent out are 

 called in by order of Council usually once a year, at the beginning 

 of the Long Vacation ; and during the month of August no book is 

 allowed to leave the house, though the Library is kept open for 

 purposes of reference. 



Besides the printed books, the Library contains a rich collection of 

 scientific correspondence, official records, and other manuscripts, in- 

 cluding the original manuscript, with Newton's autograph corrections, 

 from which the first edition of the Principia was printed ; the cele- 

 brated manuscript volume of the Commercium Epistolicum, relating 

 to the Leibnitz-Newton controversy on the priority of the invention 

 of fluxions ; the manuscript of John Aubrey's Memoires of Naturall 

 Remarques in the County of Wilts, written in 1685 ; a collection of 

 over 300 letters by Leeuwenhoek ; a collection of letters and manu- 

 scripts by Malpighi ; a collection of letters by Henry Oldenburgh 

 and Dr. J. Beale written to Robert Boyle ; Henry Oldenburgh's 

 Commonplace Book, containing drafts of his letters to Milton and to 

 Robert Boyle ; the autograph manuscript of Wallis's Treatise on Logic, 

 published in the folio edition of his works ; a large album containing 

 original letters, portraits, and other memorials of Joseph Priestley, 

 collected by James Yates, etc. Many of the manuscripts and most 

 of the manuscript letters are given in the Catalogue of Miscellaneous 

 Manuscripts, compiled by the late J. O. Halliwell-Phillipps, F.R.S., 

 in 1840, which is on sale (price 2s.). Among the series not there 

 catalogued are The Boyle Papers, bound in fifty-three volumes, the 

 Letter Books, containing copies of the early scientific correspondence 

 from the foundation of the Society to the end of the seventeenth 

 century, the Register Book of the Royal Society, containing copies 



of scientific memoirs communicated to the Society from 1661 to
