Newlands studied at the Royal College of Chemistry and worked as an analytical chemist. Continuing the work of Johann Wolfgang Döbereiner with triads and the work of Jean-Baptiste Dumas families of similar elements, he published in 1865 his 'Law of Octaves', an innovative concept proposing the periodicity of the chemical elements arranged in order of atomic weight. He pointed out that every eighth element in this grouping shared a resemblance and suggested an analogy with the intervals of the musical scale. John Newlands put forward his law of octaves in 1864 in which he arranged all the elements known at the time into a table in order of relative atomic mass. When he did this, he found that each element was similar to the element eight places further on. For example, starting at Li, Be is the second element, B is the third and Na is the eighth element.
The incompleteness of the table alluded to the possible existence of additional, undiscovered elements. However, the Law of Octaves was ridiculed by some of Newlands' contemporaries, and the Society of Chemists did not accept his work for publication.
