The physiognomical system of Drs. Gall and Spurzheim; founded on an anatomical and physiological examination of the nervous system in general, and of the brain in particular; and indicating the dispositions and manifestations of the mind
A 1815 London and Edinburgh treatise by phrenologist Johann Gaspar Spurzheim, presenting Gall and Spurzheim's theory that the brain's form reveals character, aimed at physicians and general readers of the period. Its engraved plates show heads in profile with numbered Roman-numeral markers over the skull and ear, where a designer might draw on the sepia tones, hair rendered as flowing tonal lines, and diagrammatic clarity of early scientific engraving.
