380 “ Evolution as applied to the [J U ^Y> 
In the lawful evolution of the system, — in the distribution 
of its masses, distances, motions, excentricities, and so 
forth, — we meet the relations — 
1:1*69=1:^8*013; 17 2=^9*013; 1*85=^12*260 
connected and modified by subordinate mutual disturbances. 
r6g :: 1-85 produces the mean term 1*77, and — 
8-013 x 177 = 14*188 = N.

group the predominant elements in the probable order ol 
contemporaneous, successive, and continuous evolution from 
the Primaries ; continuous, because the preceding elements 
do not vanish when the later ones increase in the condensing 
cosmic mass.

(N x 5) 4-2 = 35*470 = Cl. N, circulating by solar aCtion 
from and to Aq, becomes Cl ; five N are made in one, con- 
densed, and split — by organic fission, may be. Cl is, 
besides the primaries, H, 0 , N, the one element gaseous 
under ordinary circumstances, but differs by being coloured. 
“ If chlorine be compressed, so as to reduce it to a volume 
five times less than it occupies at the ordinary pressure of 
the atmosphere, it becomes liquid, with the density 1*33 ” 
(Regnault, Chem.). The pressure which liquefies Cl at 
ordinary temperature is “ four atmospheres ” (Graham, 
Chem.). The gas Cl, with an equivalent and density 
2*5 times that of N, reduced to 14(2*5x2) its volume, be- 
comes liquid when the pressure exceeds that of the atmo- 
sphere, as the surface of the Earth exceeds that of the 
electricity ill-conduCting portion, the land, the 14-3*83 of 
the surface ; more elevated than the conducting sea, four 
times when the weight of the whole atmosphere to that of 
its portion resting on the land is considered. The excess in 
density, 0*33 of liquefied chlorine over density 1 of water, 
is 0*33 ; the addition is therefore 1-44 of the density of the 
new liquid generated in the sea, and corresponds to the 
preceding relation of atmospheric pressure, of the resisting
