Die umständliche Beschreibung der Dampfmaschinen
Die umständliche Beschreibung der Dampfmaschinen is a German-language engineering treatise on steam engines, published in 1801 by the Andreaeische Buchhandlung and written by Prony and Langsdorf for engineers and mechanics. Its folding copperplate sheets show boilers, cylinders, pumps, valves and masonry furnace settings in precise cross-sections and elevations, drawn in fine hatched lines with lettered reference keys, offering a designer clear mechanical diagrams and structural drawing conventions.
