A system of phrenology / by George Combe.
George Combe's 1830 Edinburgh and London treatise A System of Phrenology, a medical and popular text for readers of the period who wanted to map character onto the skull. Its pictures are plain line profiles of heads set over a grid of squares on a dark ground, with starred marks and dotted lines locating the supposed seats of faculties, a schematic diagram style a designer could borrow for clean, instructional head diagrams.
