(Band 4)
This is volume four of Friedrich Justin Bertuch and Carl Bertuch's 1802 illustrated natural history series, issued in German with plates numbered by class (Vögel, Fische, Vögel, Fische) and held by Heidelberg University Library. The plates are engraved, numbered figure by figure, showing birds and fish in profile on branches or rocks against plain paper. A designer might take their clean outline work and tight figure-numbered layouts as a model for scientific-looking specimen sheets.
