Elements of phrenology / by George Combe.
A phrenology textbook by George Combe, published in Edinburgh and London in 1855 for students of the subject. Its pictures are side-profile line engravings of human skulls with numbered and lettered landmarks, showing how skull shape was mapped to supposed mental faculties. A designer might draw on their clean hatched shading and the schematic, diagrammatic way the outlines are labelled.
