sliding-press was fully developed out of the skeleton door. No thought of it had ever crossed the minds of the original designers of the building yet they could have made no better arrangement had this been planned with an especial view to its introduction. They had even made the storeys of exactly the right height, eight feet. I have not hitherto mentioned that the press takes books both before and behind, because this feature is not essential, and must indeed be departed from when the press is applied to the accommodation of newspapers and such like large folios. For ordinary books it is manifestly a great advantage, but carries with it the obligation that the presses shall not be higher than eight feet, or, when full on both sides, they will be too heavy to work with comfort, unless, which I do not think impracticable, machinery for the purpose should be introduced.

The earliest example, apart from casual and accidental applications at Trinity College, Dublin, and, as I have been told, the Bodleian, was, I believe, at Bradford Free Library, and the gentleman entitled to the credit of its introduction there was
