Versuche über die gereizte Muskel- und Nervenfaser : nebst Vermuthungen über den chemischen Process des Lebens in der Thier- und Pflanzenwelt
A scientific treatise by Alexander von Humboldt, published in 1797 in Posen and Berlin, addressed to physiologists and natural philosophers on electrophysiology and the chemical processes of life in animals and plants. The only picture is a letterpress title page, set in spaced capitals with a centred Latin epigraph, offering a designer a model of late eighteenth-century German typographic hierarchy: wide tracking, centred symmetry, and restrained use of rules and ornament.
