Contributions to the general etiology and pathology of the insane
A medical study by Aleš Hrdlička, published in Albany in 1896 and aimed at physicians and asylum specialists, on the causes and pathology of mental illness. Its two pictures are rotated family pedigree charts from the period, with hand-drawn circles and squares in red, grey and black, linked by lines and annotated in longhand, a layout a designer could borrow for diagrams or genealogical graphics.
