A. An analytic demonstration OF the
constant relation which exists between
Inc movement OF rotation and the move
ment around the sun in each planet The
nrooI that those two movement are neces'
sarily of the same nature, both uniform
or both variable. Conclusion that the
motion of the earth as well as OF the 9th
er planets, on their orbits cannot be clip
tic. but are circular and uniform. Elk
PLANTATION and evidence of the illusions
which induce TO believe in the elliptic mo-
uon OF the planets and the eccenIrclty OF
| their orbits.
s. The physical constitution orthe sun /;
its volume. mass density, temperature,
period Of rotation.
6. The nature ofthe spots on the suns
disk; their cause; explanation OF their
movement and of other appearances US.
ually observed in the solar disk, and OF
those remarked during totoI ecIipses OF
said disk. Explanation of zodlcal llght'
oflhe belts of Jupiter and OF those oil ga
turn.
7. Theory ofthe fixed stars,-They are
not so many suns. Each star is collec-
ton of planetary bodies in motion around
an invisible sun. The telescope has com,
menced TO verify this theory, by resolving
grea. many stars into two or three 9TH
ers revolving in regular orbits. Explain
alton of the cause of the sclntlllaton oil
the stars.
8. The nature of the lmpulsive acclden-
tai forces which incline for certain time
the orbit and axis Of the planets. Coin
cidence between the period of action o:
said mpulsive forces and the appearance
of each Of the organic reigns which have
succeeded each other upon Earth.
8. OF comets and their functions IN the
mechanism oil the world.
TO- Cosmogony Of the satellites Such
bodies huye been separated from the mass
Iof the planet they accompany, by the sud
den and violent action of the same tran
sient forces which incline the orbit aud
axis of the planets.
II. Discovery Of the fundamental or
ground plane Of the solar system. 1t Is
the equatorial plane oil the sun. Accord
ance Of that theory with the calculations
of LApLACE for the determination OF that
Unavailable and unknown pIane--The So
lar system does not oscillate, as it is sup
posed, upon a mean state. All planetary
movements have taken place, at certain
periods, in the fundamental plane by the
same perturbation which have inclined
the axis, they return slowly to that plane
and have a tendency to fix there.

IAe eguinoreS, and OF the direct motion Of
the petroleum of the earth. Determine
ton, by means Of such phenomena, ofthe
