Abstract
331,255. Humphreys, A. G. March 27, 1929. Anthropometrical appliances. - A device for assisting and testing the memory comprises a series of base members provided with transverse channels so shaped that one only of a series of elements will correctly fit into any base member, each pair of corresponding parts bearing respectively a question and its answer. The device may be made from a strip of cardboard or other material 8 cut along two similar or dissimilar lines 9 spaced apart at a constant mean distance, the outer elements 2, 3 so formed being secured to a backing strip and the whole then subdivided along lines 10, either or both of the lines 9, 10 being arranged so that no two sections are alike. The lines 9 may be of sinuous or wavy form or of toothed or other formation, and the lines 10 spaced apart at an interval different from that of the pitch of the undulations of the lines 9; further, the lines 9 may be displaced relatively to one another to provide additional series.
