Phrenologische Bilder : zur Naturlehre des menschlichen Geistes und deren Anwendung Wissenschaft und Leben
A German phrenology treatise by Gustav Scheve, published in Leipzig by J.J. Weber in 1855, presenting the theory that skull and head shape reveal mental faculties. Its pictures are fine engraved profiles, busts and skull diagrams, with lettered regions on the skull and a designer might take from them the clean hatching used to model faces and bone.
