The feebly inhibited; Nomadism, or the wandering impulse, with special reference to heredity, Inheritance of temperament
A 1915 Carnegie Institution of Washington monograph by geneticist Charles Benedict Davenport on heredity and temperament, written for scientists and researchers studying inherited traits. Its pictures are family pedigree charts using squares for males, circles for females, filled shading for affected members, and Roman numerals marking generations, a clean diagrammatic style a designer could borrow for genealogy or family-tree graphics.
