The physiognomy of mental diseases
Alexander Morison's 1838 London treatise, published by Longman and Highley, uses pencil sketches of faces to illustrate how mental illness shows in the features, aimed at physicians and students of asylum medicine. The four sketched heads are soft, shaded portraits of men in three-quarter views, with loose hatching and warm tan paper; a designer might borrow their expressive gazes and tousled hair for character studies.
