(Band 3): Die Acantharien oder Actipyleen Radiolarien
A scientific monograph by Ernst Haeckel, published in 1888 in German, with plates from the Heidelberg University Library, documenting Acantharia, a group of single-celled radiolarian marine organisms. The one plate shows a spherical skeletal lattice drawn in fine line engraving, with lettered labels and spines radiating outward, giving a designer a model of geometric, organic tessellated structure.
