9 We will now commence with the different modes of printing, and therefore name the four principal polygraphic departments of art, namely -— The rnilctl printing, with the punch-cutting, the letter-foundry, printing as well for those who see as for the blind, stereo- typing, typometry or the calculation of room, the knowledge of types, xylography or wood -engraving, chemitypy. SlYPh°8`”PhYi The concave printing, with the chalkography, the siderography, galvanograpby, stylograpliy, hyalography. engraving, guil- loche—mal:ing, diminution of engraved plates; The chemical 4 printing, with the lithography. the chemigraphy. anastatic, chromo-lithography or colour- printing in ge- neral; . rho natural solbsoting printing process, with the galvano— . plastic, the Daguerreotypy, photography, and microtypy, and will join with an explanation of the same our opinion with regard to their practical application in a mentally ennobling, as well as in a material or profitable point of view. . The first department mentioned includes all that man may want in the sphere of nature, art and science; and the creation of Pinakotheks and Glyptothelts, and even of whole museums for natural history and archaeology, might be ascribed to the multi- plying apparatus, besides its establishing libraries. Hitherto the press was occupied with the printing of books and pamphlets for every day use and with the representation of pictures in a more limited sense. What one party printed, another party tried to draw within the extend of his activity, and, in consequence, this competition caused some interruption in business, so much the more so, as the department of the gra- phical branches of art is too limited as it is, and excludes the multiplimtion of numerous objects which all belong to the printing department.
