departments has been taken, it will be necessary to reprint the earlier volumes of the catalogue; and the £1500 required for this purpose might probably be obtained from subscribers on condition of the other back volumes being thrown in as a bonus at a greatly reduced price. The longer the operation is delayed the more costly will it be for the Museum, which runs the risk of eventually finding itself with a hundred sets, mostly imperfect, on its hands, of which it will be impossible to get rid otherwise than by donation. A subscription once commenced is not likely to drop, as the value of a set of the catalogue depends upon its completeness. It will now be naturally inquired, at what period may the completion of the catalogue be looked for? The answer will be, about the end of the century, if the Treasury grant is maintained at its present figure. The amount expended in printing, inclusive of that incurred for printing the titles of books added to the library, is about £3000 annually. Two years ago the grant for purchases throughout every department of the institution was reduced by two-fifths, and only half the amount has as yet been restored. If a similar mistaken spirit of economy had affected the grant for printing, the completion of the catalogue must have been proportionately delayed. Any expectation, therefore, which may be held out of the accomplishment of the work by the end of the century, or any other date, must be understood to be entirely subject to the action of the Chancellor of the Exchequer, who has it in his power to retard progress indefinitely, or interrupt it altogether. It must be acknowledged that the behaviour of the Treasury towards this department of the Museum service has hitherto been very liberal; and that the grant for printing is as large as, with the numerous other demands upon the library staff, can be employed to advantage. The preparation of copy for the press, and its subsequent correction and revision, occupy the entire time of several of the best assistants; and, were absolute bibliographical accuracy aimed at, would require that of several more. This cannot be had, and all pretension to minute accuracy has invariably been disclaimed. It has been felt all along that a number of trifling errors are preferable to the huge and unpardonable error of not accomplishing the work at all. From what has been said, it will be apparent that the publication of this catalogue is carried on under very different conditions from those habitual in similar undertakings. Three thousand pounds a year must be spent upon it; or, as regards Museum purposes, must be thrown away. Any balance unexpended at the end of the financial year must revert to the Treasury, and would be an uncompensated loss as regards the Museum. This misfortune has hitherto been avoided—partly by an energy and diligence on the part of the gentlemen employed, of which it is impossible to speak too warmly or too
