168 Record of the Royal Society. 



In addition to the foregoing, the President and Council have 

 determined 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, and the copy for 

 this volume is now in an advanced stage of preparation. The work 

 for the decade 1883-94 has also made some progress. 



The question of a Subject Catalogue has been often considered, 

 and the Society have actually on foot a Subject Index to the existing 

 Catalogue. The preliminary preparation of the copy, involving the 

 reduction of all the titles to one language, is now far advanced, and 

 the scheme of classification is under consideration. A portion of Dr. 

 Ludwig Mond's gift, which has been mentioned above, is devoted to 

 this branch, of the work, and in June, 1894, he supplemented this 

 important aid by the still more munificent promise to contribute 

 one-half of the total expenditure upon the Index in excess of that 

 portion of his former gift already devoted to this purpose, provided 

 the Society or others are willing to contribute the remainder of such 

 sum (see p. 120). By this means the Index to the Catalogue will 

 doubtless in due time become an accomplished fact, and thus the 

 whole series from 1800 to 1883, under Authors and Subjects, be com- 

 pleted. And the Society looks forward to being able to continue the 

 whole work up to the year 1900, at which date it is to be hoped that 

 an international organization, the consideration of which was the 

 subject of an international conference held at the instance of the 

 Royal Society in July of last year, may take it up. 



THE LIBRARY. 



On the 2nd January, 1666-7, Mr. Henry Howard (afterwards 

 sixth Duke of Norfolk) presented the Royal Society with "the 

 Library of Arundel House, to dispose thereof as their property, 

 desiring only that in case the Society should come to faile, it might 

 return to Arundel House ; and that this inscription, Ex dono Henrici 

 Howard Norfolciensis, might be put upon every book given them." 

 "The Society," it is added, "received this noble donation with all 

 thankfullnesse, and ordered that Mr. Howard should be registered 

 as a benefactor." This gift may be regarded as the nucleus of the 

 Society's Library. 



A considerable part of the Arundel Library came originally from 

 the collection of Matthias Corvinus, King of Hungary, a portion of
