catalogue of the world's literature partakes of the mobility of the world itself. Designations are altered, as when successful generals become barons, or popular churchmen bishops; anonymous authors are brought to light; periodicals and works in progress are completed or relinquished; errors are detected and corrected; improvements and modifications are introduced. The catalogue of an institution like the British Museum, dealing with a mass of matter already accumulated, and intended to register an ever-accumulating mass of matter for ever and ever, must not aspire to absolute perfection, and can never attain finality. A few words, in conclusion, upon the duty and interest of the public to support the Museum undertakings, and the practical end at which, as it seems to me, we ought to aim. The catalogue cannot, at the present rate of progress, be completely printed in much less than forty years. We shall all agree that this progress ought to be accelerated, but this can only be by increased liberality from the Treasury. This will be accorded in proportion to the Treasury's conviction of the value of our work, and this conviction will greatly depend upon the appreciation of this usefulness manifested by the public. If we are to do a national work, we must have national recognition. I am not at all using the language of complaint or disappointment. It would be well worth the Museum's while to print the catalogue for its own sake, even if it did not dispose of a single copy; and in fact the number of subscriptions is very much what was expected. I wish, however, that we could succeed in this, as in some other things, beyond expectation. Something is probably to be ascribed to the peculiarly quiet manner in which this great change was effected. Mr. Bond's reforms "come not with observation." A question which had been so long and clamorously agitated while unripe was, being ripe, settled in a few conversations, and with a little official correspondence, so noiselessly and unostentatiously, that many of those most interested in the matter have never heard of it. Many who have heard of it are probably under the impression that the original high terms of subscription have been maintained. This is not so. All the sections of the Accession Catalogue are now issued for an annual subscription of £3; and all volumes of the General Catalogue for an annual subscription of £3, 10s. This does not bring it within the reach of every purse: still there must be many students and men of letters in easy circumstances who would find it well worth their while to secure on such terms a register of the literature of the world. Our late lamented friend and colleague, Professor Jevons, was a type of the class I have in my mind; and I know that on the eve of his death he had determined to become a subscriber. From another point of view it may be urged that to support the Museum Catalogue is to take a long step towards the
