When these are heated, paper is said to be hot-pressed.The rollers are kept in opposition by adjusting screws, andthe pressure to which the paper is subjected is very great,the surface of rough paper becoming highly polished onleaving them. In other instances one steel roller is em-ployed under the paper, wliile the glazing roller is a turnedcylinder of paper. This cylinder is formed of an immensenumber of discs of thin highly-sized paper, which arecemented together and united by the hydraulic preas intoa cylindrical roll, and when sufficiently firm the mass isturned true in a lathe. Most probably the papers ex-hibited have been glazed by a somewhat similar apparatus.—R. E.] _
