striker limits of the development of the system. Is it all 
terrestrian ? is it no element? When 131 = 71*070x3, or 
the equivalent three atoms, we get 2Fe : Bi = i : 3*83 as the 
non-conduCting part to the surface of the Earth, See. 
Silver, 108*305, to gold, 199*208 = 1 : 1*83. 
Palladium, 53*359, to platinum, 98*841 = 1 : 1*85, &c. 
The “ development theory ” gives the origin of the rela- 
tions 1 : 1*7, 1 : 1*72, 1 : 1*85, marking the extremes and 
means of solar distance in the motion of the two great 
planets, the motion of the system having its correspondence 
in the central mass, and their continuity in ascent and 
descent of proportions, of mutual disturbances within the 
whole system. The return of similar relations of atomic 
weights between kindred elements, and prominently between 
the dominant elements, is therefore significant for the meta- 
physics of elementary evolution. 
I have not yet mentioned mercury — a rare, yet important, 
and in its qualities exceptional, element. The atom is 
101*431, to which applies what was said of Bi. It is next 
above the suspected Bi in inferior eleCtric and thermic con- 
dudtivity. Hg : Cl = 101*473 : 35*470 = 2*83 : 1 as sea to 
land, or, inversely, the density as the condudting to the 
insulating surface of the Earth. 
Like H, it has and has not characteristics of a real metal. 
The atomic weight of this poor conductor is 8*013 - 1 = O — H 
less than that of the prominent conductor, silver. Hg is 
liquid at ordinary temperature, and dissolves most metals 
directly ; when warmed, tin, lead, zinc, bismuthum, a group, 
the two latter evaporating with Hg in rectification. It 
easily dissolves gold and silver. For the extraction of 
silver from its ores, NaCl 2 is added to Hg ; the metallic 
water moistening the ores is made ocean water ; the pro- 
portion of weight in HgCl combining with Ag is — 
Hg 74*09 : Cl 29*97 = 2*83 : 1, 
the relation defined. The density of Ag at ordinary tem- 
perature is to that of solid Hg, at — 40° C., — 
10*542 ; 14*391 = 1 : 1*33 = water to liquid chlorine. 
The limits of liquidity are for Hg — 40° C., for Ag near 
iooo 0 C., water at o° being the standard limit, 40° to 
966°= 1 : 24*16 (ref.). 
The equivalency of iron, 2Fe : Hg= 1*182, as their density 
when both are solid. Their conductivity is Fe ; Hg when 
both solid, 57 : 1 ; when Fe solid, Hg liquid, 6*7 : 1, — both 
characteristic figures for Aq (ref.).
