Multiple Proportions of the Atomic Weights. J J 



found to subsist between planetary and molecular systems, 

 as disclosed in my paper. 



The positions of Hg = 200, and Pb = 2o8, as the highest 

 members of the series H« and \\2n afford me the oppor- 

 tunity of dealing with the question of periodicity or recur- 

 rence of properties, which has been supposed to exist when 

 the elements are arranged in seriatim order of their atomic 

 weights. 



Newlands fixed the recurring period at every eighth 

 element, commencing with hydrogen;* while Mendeleeff 

 selected the eighth, eighteenth, and two or three other odd 

 periods of recurrence.t 



I shall now demonstrate that when the seriatim order of 

 the atomic weights is rightly adhered to, the idea of recur- 

 ring properties, or periodic functions, in terms of the vertical 

 series of Newlands, or the horizontal series of Mendeleeff 

 has no real existence in nature. 



In order that a clear conception may be formed of the 

 principle of the alleged periodic law, as defined by these 

 chemists, and shown in their respective tables at the end of 

 this paper, I will arrange a series of consecutive numbers, 

 with a repeating series of seven letters, to represent the 

 elements in recurring periods, as in the table of Newlands, 

 and at the same time apologise for the somewhat elementary 

 character of the illustration.
