Traité élémentaire sur les procédés en usage dans les fonderies pour la fabrication des bouches à feu d'artillerie, et description des divers mécanismes qui y sont établis
A French technical treatise of 1810 by Dartein, published by Levrault, describing foundry processes for casting artillery cannon and the machines used in them, written for military and metallurgical workshop practitioners. The plates are engineering line drawings of boring and turning machinery, casting pits, and moulds, drawn in fine black outline on pale paper with dimensioned parts and lettered reference marks. A designer could draw on their precise, diagram-like linework for mechanical schematics, plan views, and labelled technical callouts.
