One of our two icosatoms, though marked as differentiated, and consisting of 

 twenty-two elements, is completely isometrical, and in its atmosphere spherical. 

 It is therefore suitable for the liquid state at any temperature, as might be shown, 

 but for the necessity of avoiding here all morphological exposition.

* The relation between the atomic weights of these eminently active or basilous metals to each 

 other and those of the principal constituents of the crust of the earth is very interesting. Thus, esti- 

 mating their functioning by their respective attractions to the earth (their weights), the first, Lithium, 

 simply by doubling and doubling again, gives nitrogen, aluminium, and iron, disregarding fractions 

 in atomic weights, and taking the integers immediately above them, — 



2Li = 2x7 = 14 = N, Si and Al 



4Li = 4 X 7 = 28 = Fe, and its companions. 



Then the sulphide or deutoxide of each gives the metal in the series immediately above, — 



Li =Li=7. 



LiOg =Na = 7 + 16 = 23. 



Na02 = K =23 + 16 = 39. 



Further, if we take Na at 24, and K at 40, which may be the primaeval unreduced or full weights 

 I of these elemental bodies, then, by dedoubling, we obtain weights to complete the series, —

'Thallium, in our theory, comes out a composite metal, of the type X Xg^X. The body being sulphu- 

 rium, the poles sodium, all locked together. 



Tl = NaS2oNa=23 + 160 + 23 = 206, or 208.
