introduction of printing, there was not room to place another volume. A column of the type used in printing the catalogue weighs ten pounds, so that supposing the work, when through the press, to consist of 600 volumes averaging 250 columns each, a million and a half pounds' weight of type will have been employed.
From the preparation of the catalogue for strictly Museum purposes, we pass to the arrangements for its issue to the public. Here we are confronted by two very remarkable facts one as gratifying as the other is the reverse. For the original subscribers the Museum Catalogue is one of the cheapest books in the world. At its commencement it was not expected that more than fifteen parts could be issued annually, and the annual subscription was fixed at three pounds. In fact, however, the rate of publication has for some years past averaged thirty parts, while the terms of subscription remain unaltered. The subscription is, therefore, virtually reduced by one-half, and the cost of each part, with its 250 columns and 5000 titles, is just two shillings. It may be doubted whether equal liberality has ever been shown by any public institution. The case, however, of the subscribers of the future is far otherwise, or rather say would be, if such subscribers could exist. Nobody will take an imperfect catalogue, and the sum required for the parts already printed is an almost insuperable obstacle in the way of new subscribers, and an effectual bar to the further dissemination of the catalogue, except by donation. It would be well
