Photo-Lithography.

This name has been applied by the discoverers, Messrs. Cutting & Bradford, of Boston, to a new and beautiful application of the photographic art, which is evidently destined to revolutionize, in a great measure, the ordinary processes of lithography. The requisites for the production of the effect are, in the first instance, a well ground lithographic stone, and a glass negative photograph. The stone, by a peculiar treatment, which is really the discovery itself, and is yet a secret, is prepared in a few minutes to receive the photographic impression, through the glass negative, by exposure to sunlight. The stone picture can then be washed, inked, and any number of photo-lithographs printed from it upon paper, by means of the usual lithographic press. The invention is not yet, we believe, wholly perfected, but the results alluded to are most remarkable, and microscopic objects, especially, are wonderfully depicted. The value of this discovery, as applied merely to the illustration of books, especially scientific treatises, is obvious.
