among the primaries,
The two inner moons OF Jupiter ar,
smaller than the two outer moons Snt
inc same relation obtains between the In.
ternal and external ones constituting The
Tour discovered satellites. of Uranus
while Of the group Of eight saturniar
moons, the three outside ones arc large
and the five inside ones are small Bul
this is not all. The outermost Jovian

The sixth and seventh, and not the eighth.
Ihese condolences, indicating repeu-
Ilon Of results IRON similar causes, point
TO common mode oil genesis, and serve 10
strongly support the probability OF the
Nebular Hypothesis. Again, the hypothe.
sis requires accelerated orbital rotations
IN the planets, as we approach from the
exterior TO the Interior, and also that the
BUN and each planet should reyolye upon
lts axis IN Q shorter period, than the Or
oltal revolution OF any Of its immediate
satellites, and this condition is PERFECTLY
observed In both the primary and sec
ondary systems Of satellites. Il has more.
over been shown by calculation, that the
maximum velocity which the force OF Inc
suns attraction could control In anv
planet, Is equal to the observed velocity
OF the planet next nearest the Sun: That
ID 70 say, II Saturn was to suddenly ac-
quire the orbltal speed of Jupiter, il
would just be freed from solar attraction,
and would fly of into space; or, If the
EARN had the angular velocity OF Venus,
similar catastrophe would occur In its |
case. These facts illustrating a mechani.
cal principle, which Is natural corollary
from the nebular theory OF the planetary
genesis, gives additional weight 10 the
probability Of planetary genesis In that
manner.
THE CONDENSATION OF THE EARTH.
nultaneously with the progress of
other planets and of the sun, a like pro.
cess OF evolution has been experienced bv
ne earth. Cast of as the seventh nebu.
Gus ring from the original mass, II has
aggregated into a rotating spheroid, and |;
gwen rise to one genetic ring in It's turn |;
which Is destined TO become its future
noon. Its continued concentration and Ii
9diation o. heat have brought It's parti-
,les go nearly into contact that prayita-
ion has become powerful, and the weight

q me central gaseous portions into a
liquid form. But now, heat being parted
With much more rapidly at the surface OF ,

Will be so much reduced that the less
asily volatilized elements, such as silicon !!
:alclum and aluminium, will unite with
he contiguous oxygen, and, assuming the !
lquid form, will descend like molten rain

alton OF the descending matter. This !

FORMATION OF THE RARTH's CRUST.
Great chemical actions will now lake

xygen will unite with silicon 10 form T,
lartz, and with calcium, aluminium, iron, :
Otassium, and other metals, to form the y
!ineral bases, which compose the crust n
the earth. AS radiation of heat pro- q
resses, film will gradually form over p

owly thickcn until a comparatively firm d
'ust is produced. ~ :.
In the meantime, hydrogen, the lightest n n

nited with It in the form Of steam. But ~
additional heat is parted with, this i'm. -

PREPARING FOR THE ADVENT OF LIFE, u
But in course Of time the incessant rain.
il and accompanying evaporation would
far cool the earth's surface, that the
lowers OF water which descended would n

1combined oxygen and form the atmos- s
