Ka = 39*257 ; Na + S = 23*2io + i6*ii4 = 39’3i8; 
Na : Ka=i : 1*7. Complement barium =68*663 ; 
ICa : Ba = 1 : 175. 
After the “ metalloids” we get the “ alkaline metals,” and 
pass to the “ earthy metals.” I place silicon last, and pre- 
fer the old 22*221 to the modern 21*3. 
The preceding elements increased in weight, as products 
of the union apd new re-partition of primary elements 
during the contraction of a semi-nebular agglomeration of 
solids, liquids, and gases, of imperfeCt separation and strati- 
fication, and of great alternations of contractions, expan- 
sions, and temperatures. The “ earthy metals ” represent 
the transition from sea to land ; the formation of more 
stable solids, by the reduction and decomposition of greater 
to smaller but denser atoms, requiring less pressure and less 
low temperature for solidity. 
Mg : Al = Ca : Si, 12-676 : 13*720 = 20*515 : 22*211 : 
: Mg : Ca = Al : Si = i : 175^1*07 (ref.), 
therefore Mg : Si= 1 : 1*75 = C : Na. 
Iron, the dominant metallic metal, has under ordinary 
circumstances 2*83“ times the density of ice, 1 : 2*83 being 
the surface of land to sea, and the density of water to land 
(ref.). It is a good conductor of heat and electricity : it is 
the magnetic element, with a decidedly polar arrangement 
of the atom or equivalent 2Fe. 
The generation of iron might be satisfied by various com- 
binations, for instance, by the condensation and mutation of 
2A1 = 27*464; but elementary generation is rather the re-distri- 
bution of matter in the abstract, not comparable to chemical 
combination. The earthy metals arose from the decomposition 
of the alkaline metals, with accession of the metalloids; the 
metallic metals produced by greater pressure and condensa- 
tion under greater heat show, with a re-combination of pre- 
ceding atoms, are-increase of atomic weights. When we look 
on the Earth as having been first a galvanic cell, then a 
battery, an arrangement of many cells, gradually become a 
dynamo-machine with a condensed thoroughly ferruginous 
nucleus, separated by a frictional, heated, mutating stratum 
from the insulating prominently silicious shell, whose outside 
is wound round by ocean streams, conducting and propelling 
electricity, moving between the separating insulating conti- 
nents they raised by lateral pressure and motion, all wrapt 
into the di-eleCtric air, traversed by conducting vapour, we
