NATURE PRINTING.—The specimens exhibited of this new process for obtaining life-like or physiotypic impressions of plants are mostly of Ferns and Mosses, but the process is still further peculiarly applicable to the representation of the Grasses, the Lichens, and the Sea-weeds. These results are obtained by placing the specimen to be copied upon a plate of soft lead, with a highly-polished surface, and passing it, at a high pressure, between hard steel rollers. The specimen leaves its impression upon the lead, and gives not only its outline, but also the most delicate elevations and depressions of its surface with that sharpness and fidelity as to present a perfect fac-simile of the original specimen in its natural size. The lead plate thus impressed—not being practically available for printing purposes—is copied by the electrotype process, by which a copper plate (the image on which is perfectly identical with the original impressed lead plate) is obtained, which can be printed from at an ordinary copper-plate press.

Nature Printing was introduced into England by Mr. Henry Bradbury, in 1853; the first application of the process has been most successfully exemplified by him in the magnificent folio Edition of “THE FERNS OF GREAT BRITAIN AND IRELAND,” Nature Printed. Descriptions by Thomas Moore, F.L.S.; Edited by Dr. Lindley. Imperial folio, with 51 Nature-Printed plates. Price £6 6s.
