Wrigley's Lamina System

In two papers: A.N. Wrigley, W.C. Mast, and T.P. McCutcheon, "A Laminar Form of the Periodic Table, part 1," Journal of Chemical Education 26 (1949): 216-218 and A.N. Wrigley, W.C. Mast, and T.P. McCutcheon, "A Laminar Form of the Periodic Table, part 2: Theoretical Development, and Modifications," Journal of Chemical Education 26 (1949): 248-250 a Laminar Periodic Table is introduced. (Thanks to Ann E. Robinson for this informaton & references.)

This formulation was discussed and re-drawn by van Spronsen in 1969:

There is a Russian publication "100 Years of Periodic Law of Chemical Elements", Nauka 1969. On page 87 there is a formulation that appears to be a version of the van Spronsen re-drawing. The caption says: "Volumetric Model of 18-period Long System of D.I.Mendeleev." after Riggli (1949). (Thanks to Larry T for this.)
