Graphic representation of the periodic table of chemical elements based on the Law of Octaves, which surmises that, when arranged by increasing atomic weight, chemical elements with similar physical and chemical properties will occur after each interval of seven elements. This table was originated by British chemist John Alexander Reina Newlands (1837-1898) in 1865 and classified by chemist Edward G. Mazurs as Type IC1-1 in his seminal work Types of Graphic Representation of the Periodic System of Chemical Elements (1957). Notably, Newlands was the first to devise a periodic table of chemical elements arranged in order of their relative atomic masses, with periods going down the table and groups going across. This illustration appears as Figure 22 on page 105 of Mazurs' 1957 publication.</div>
