A system of phrenology
A system of phrenology by George Combe, published in Boston in 1839 by Marsh, Capen, Lyon, and Webb, is a treatise setting out the theory that character and mental faculties are located in regions of the brain and read from the skull's surface. Its pictures are engraved diagrams of head profiles overlaid with grids and numbered zones, with bold outlines on dark hatched grounds, offering a designer a clear model for schematic, measured anatomical charts.
