1886

Reynolds' Method of Illustrating the Periodic Law

Reynolds, J. E. (1886). Note on a method of illustrating the periodic law. Chemical News, 54, 1–4

Ann E. Robinson comments:

"Reynolds published a zig-zag version he created, noting it had been 'used in my lecture-room for some years in order to illustrate the periodic character of the relation between the atomic weights and properties of the chemical elements.'

>"Rather than a tabular form, Reynolds's form was a curve, best visualised as a string with seven knots tied in it at regular intervals, providing a 'vibrating system'. Although Reynolds's diagram is presented only as a two-dimensional picture, in a note he remarks that a friend suggested that the installation of 'a vibrating metallic chain, suspended from the ceiling and attached to the floor, would afford a more complete picture.'":
