 Rh commenced, and has since been carried on uninterruptedly. The order of publication was not at first alphabetical, the Treasury's support having been partly gained by the promise to deal, in the first instance, with the overgrown volumes in various parts of the catalogue which would otherwise have required rebinding and relaying. This accomplished, however, publication, as had always been Mr. Bond's intention, glided into as close an alphabetical sequence as is consistent with the fact that different portions of the same letter are necessarily taken up simultaneously, and that some are much more difficult to prepare. for press than others. With the adoption of print the history of the Museum Catalogue may be said to terminate for the present, while its actual condition will appear from the statement now to be given of the progress hitherto made.

By the time that these pages see the light about 190 parts or volumes of the catalogue will have been issued. Averaging the number of entries as 5000 to a volume (notwithstanding that the volumes have of late been made thicker), it will appear that 950,000 titles have been printed, or nearly one-third of the entire work, allowing for the constant accession of new material during, its progress, as will be explained further on. This gives an average of about twenty-four parts annually since the commencement of printing in 1881; but as the amount of the Treasury grant did not admit of the publication of more than fifteen parts annually for the first two years, the average publication at present may be taken as thirty.
