About this work


Comprises letters, schedules, returns, notebooks, diagrams, drafts for plates, notes and newspaper reviews. The material relates to Francis Galton's psychometric surveys, particularly on individuals' capacity for visualising abstract concepts such as numerals, sounds and time by association with images of colours, patterns, landscapes and faces. It also touches on the working of the human imagination and hallucination. The surveys formed the groundwork for essays on "Visualised Numerals", "Visions of Sane Persons" and Statistics of Mental Imagery, and particularly for Galton's book Inquiries into Human Faculty and its Development (London: Macmillan, 1883).
