Ueber Das Sehen der Farbenblindheit [electronic resource]
A German-language ophthalmology treatise on colour blindness by Jakob Stilling, published in Cassel by Theodor Fischer in 1880 and digitised by UCL Library Services for medical readers. The single plate shows an engraved lateral view of a human brain with its folds labelled by letters and a cross-reference 'FS' near the lower edge, drawn in fine hatched line. A designer might take its dense cross-hatching and cartographic lettering as a model for anatomical diagrams or technical schematics.
