______ in respect of the original schema by Dmitri Mendeleev in 1869, with reference to his proposed notion that
'the properties of the elements are periodic functions of the atomic weights'

___ further to a schema by Newlands in 1863/64, termed as 'the octaves law'
showing that when the elements are arranged in order of increasing atomic weights, the first relates as being similar to the eighth, the second to the ninth, the third to the tenth and so on.
