Richard Quain, The anatomy of the arteries of the human body...
...and its applications to pathology and operative surgery with a series of lithographic drawings [by Joseph Maclise, surgeon], 1844
Ernst Heinrich Weber's compass experiment
...If one places the points of a compass more than one centimeter apart on the nape of an experimental subject's neck, the subject can clearly distinguish between the two points (Figure). Each point is located at another place. If one moves the points down toward the back without changing the distance between them, they get closer and closer in the tactile space of the experimental subject until they seem to be at the same place. : https://germanhistory-intersections.org/en/knowledge-and-education/ghis:document-143
