are about in the following ratio 1:2:4:5:6. For 145 : 1 = 145, 

 266:2 = 133, 481:4 = 120, 579:5 = 116, 707:6 = 118. 



From the value of Tu and /^j for Hydrogen, determined just now 

 bj K. Onnes c. s., would follow the value 59.10 -^ (per Gr. atom) 

 for h]c, i. e. exactly kalf the middle value 118 for K:4, Rb:5 and 

 Cs:6. So that the ratio of the 6-values for H to Cs would become 

 V.:rA:2V3:4:5:6. 



Possible' the ratio values for Li and Na will later have to be 

 rounded off to 1 and 2 on more accurate knowledge of some data. 



And it appears again from the values of V-^ak, for which rounded 

 off we may write 23, 27, 33, 35, 37,5, that all these metals occur 

 atomically with the very much increased valency attractions. If they 

 were bound to Lij, Na,, etc., only the "r^ó'^attractions" 3, 5, 7, 9,11 

 would have manifested themselves (per G. atom). For Li it is possible 

 that undissociated molecules of L, are still present at Tk (the 

 abnormally low value 23 would point to this), but it is also possible 

 that this is not the case. All these questions must be left open for 

 the present till the lohole periodic system shall have been examined. 



In a following paper the minor group Cu-Ag-Au will be treated, 

 besides Manganese and the Iron-Platinum group.
