Abhandlungen der Königlichen Akademie der Wissenschaften in Berlin
This is a plate-numbered scientific volume of the Royal Prussian Academy of Sciences' memoirs, published in Berlin in 1822 by the Realschul-Buchhandlung for specialist readers. Its plates show close-up natural-history studies rendered in fine graphite-like shading, with bone-like surfaces, pitted textures and cellular clustered forms that a designer could use for organic patterns, surface textures and tonal study.
