Brain and personality;
Brain and Personality is a 1910 New York study by physician William Hanna Thomson, written for a general readership interested in the link between mind and body. Its four pictures are dorsal and lateral engravings of brains from different vertebrates, arranged from mammal to simpler forms, with labelled regions such as C, O and M marking cerebrum, optic lobes and medulla. A designer might take their stark hatched shading and the comparative sequence of forms as a model for scientific diagrams with leader-line labels.
