Abhandlungen der Königlichen Akademie der Wissenschaften in Berlin
An 1822 Berlin academy journal of scientific papers, published by the Realschul-Buchhandlung for the Royal Prussian Academy of Sciences and held by the Smithsonian Libraries. Its plates are fine pen-and-ink engravings of anatomical and pathological specimens, including internal organs, malformed growths, a netted disc with root-like filaments, and an inscribed stone block. A designer might take from them the precise hatching and cross-hatching of early scientific engraving, and the diagrammatic labelling of specimens with figure numbers.
