(Band 2): Atlas
An 1857 atlas volume (Band 2) by Jean-Baptiste Payer, held by Heidelberg University Library, presumably issued for botanists and students of plant morphology. Its plates are dense grids of numbered engravings showing flower buds and floral organs in cross-section and side view, drawn in fine stippled and hatched graphite-like tones that a designer could borrow for botanical linework, scientific diagram layouts, or numbered specimen panels.
