318949.1272 There are a number of these chronocyclegraph studies of locomotion (at least 9), some of which are numbered 1700.152 (etc.) and some of which are numbered in the 18000 series, such as 18198. FBG took these as part of his shoe-fitting investigations in the military motion study laboratory. It appears lights were attached to each foot, the belt, and the head; some of the wavy images suggest (intentionally) erratic walking.
