Thirty plates illustrative of natural phenomena, etc. : with a short description annexed to each plate
A plate book of thirty natural-phenomena illustrations issued in London in 1846 by the Society for Promoting Christian Knowledge, each plate paired with a short printed description for general readers. The pictures are hand-coloured engravings on a single page layout, with a central image above dense explanatory text, showing caves, glaciers, halos and the will-o'-the-wisp over marsh; a designer might take from them the compact plate-and-caption format and the period engraving style of landscape and atmosphere.
