TO DISTINGUISH A LITHOGRAPH.

In a lithograph the surface of the paper is perfectly smooth, and not indented in any way. The examples of engraved plates printed from stone, and the litho. and photo-litho’s printed in brown ink, will serve to illustrate the qualities of lithography. Unless well printed, the fine lines are apt to show weak and rotten, or to have become thick and blurred, either in transferring to the stone or by too much ink on the printing roller.
