contemplated, which I believe will be of substantial benefit to the study of ancient printing. When the requisite funds are procured, as it is hoped will shortly be the case, it is intended to provide additional glazed presses in the library, with the view of bringing together examples of every description of type used by a printer of incunabula, that is, of books produced during the fifteenth century.

This collection, though not shown to the public, will always be accessible to experts. Its value to them is obvious, and we hope it will also be of material service in disclosing the numerous deficiencies of the Museum in representative specimens of early type, and prompting efforts to make them good. There is no idea of assembling together all the incunabula in the Museum, which would be impracticable for many reasons, but only representative examples of the various types. The foundation, however, of a general catalogue of incunabula has been laid in a manner which I have previously stated to the American Library Association, namely, by printing copies of the catalogue on one side only. When the catalogue is finished we shall, by merely cutting out the entries of any particular description of books, obtain a classed catalogue of the entire subject, among others, of our incunabula; this list
