PREFACE TO VOLUME IX. 



THE three volumes of the Third Series of the Royal Society's Catalogue 

 of Scientific Papers, of which this volume is the first, comprise the titles of 

 papers published or read during the decade 1874 1883. They have been com- 

 piled upon the same plan as the Second Series, and in like manner include a 

 certain number of titles which were omitted in former volumes. These are 

 distinguished by an asterisk (*). 



The numbering of the titles of the papers of each Author whose name 

 does not now appear for the first time is consecutive with that in former 

 volumes. 



Although the abbreviations of the titles of the various periodicals from 

 which the list has been compiled are in most instances so clear as to speak 

 for themselves, and although but very slight alterations in the form of any of 

 them have been made, it has been thought advisable to amalgamate the Lists 

 of Abbreviations that have appeared in former volumes, and to prefix to this 

 Third Series a complete list of the works from which it has been compiled 

 and of the abbreviated forms under which reference to them is made. 



The list thus formed by no means comprises the whole of the scientific 

 periodicals which at the present day are being constantly published in various 

 languages ; but the President and Council have it in contemplation to issue a 

 Supplementary volume, in which will be catalogued all the most important papers 

 that have appeared from 1800 to 1883 in periodicals not hitherto indexed. 



Great pains have been taken to avoid so far as possible typographical and 

 other errors in the volumes of the present Series, but notwithstanding all the 

 care that has been bestowed some will no doubt unavoidably have crept in.
