Elements of phrenology / By George Combe.
A phrenology textbook by Scottish writer George Combe, published in Boston in 1835 by Marsh, Capen & Lyon as an introduction to the theory that mental faculties map onto skull regions. The pictures are plain engraved diagrams: one shows a carved block-like form with heavy hatched shading and cast shadow, while the other shows skulls divided by dashed lines into numbered zones, a layout a designer could borrow for schematic charts.
