An 1881 German-language popular lecture on animal magnetism and hypnotism by Christian Bäumler, published in Leipzig for a general academic audience. The single picture is a black-and-white line diagram of branching nerve or pathway lines radiating from a top point to labelled nodes, with letters such as A, B, E, H, X and M. A designer could take its clean schematic linework and radiating network structure as a model for flowchart or network graphics.
