Mr. Virgo's contrivance was, I understand, a double door, not hinged on to the original press in one piece, as in the pattern I have just described, but opening in two divisions to right and left, as frequently the case in cupboards. I speak, however, with some uncertainty, for when, writing on the subject in Mr. Dewey's Library Notes, and most anxious to give Mr. Virgo all due credit, I applied to him for particulars of his invention, modesty, as I must suppose, rendered him silent, or at best but insufficiently articulate. I hope he may be present to-day, and that the Conference may hear the particulars from himself. It is due, however, to the Bethnal Green Library, the other institution to which I have referred as having given effect to the principle of press expansion in situ, to state most explicitly that the idea of its application at the Museum was derived wholly and solely from Bethnal Green; that the Bradford example, though it had been set for some years previously, was never heard of at the Museum until the model had been constructed and the first presses ordered; and that I am satisfied that Bethnal Green knew as little of Bradford as the Museum did. The Bethnal Green inventor was, I am informed, the late Dr. Tyler, the founder and principal benefactor of the institution, and, as elsewhere, the device was resorted to by him under the pressure of a temporary emergency—in this case the accumulation of specifications of patents annually presented by the Patent Office.
