No one unacquainted with the internal economy of the Museum will fully appreciate the saving of public money, to say no more, effected by this simple contrivance.
Print and the sliding-press are now, along with the electric light, undisputed possessions of the Museum; but telegraphy and photography, the two other applications of scientific ingenuity recommended in this volume, have not yet been enlisted in her service. When the printing telegraph obtains a footing, ample occupation will be found for it. Its most useful as well as most striking application, however, will probably always be the one principally dwelt upon here, the enabling every demand for a book made in the reading-room to be simultaneously registered in the Library, thus abolishing at a stroke the vexatious delays that now intervene between the writing of a ticket and its delivery in the proper quarter. The advantage alike to the public and to the staff is so obvious that the only question ought to be as to the applicability of electrical power to the transmission of legible messages under the special circumstances, which an intelligent course of experiments would speedily determine.
If telegraphy has been neglected, the same cannot
