from the side turned away from the sun and resting on its 
central portion, — and points with a larger cone away from 
the sun, its substance issuing from the central part of the 
side turned towards the sun. After separation had taken 
place the three groups adopted ellipsoidal forms, and pre- 
sented an aspeCt similar to that which the three-linked comet 
must have shown about which Chinese chronicles tell us. 
The mass has four poles reduced to the equatorial plane ; 
Jupiter and Saturn, the interior and the exterior system, 
each of the two latter systems presents again four poles. 
The mass, in shape three coupled zeros, circulates in double 
motion, and concentrates at the points of intersection and 
reversion. The asteroids are fragments and vapours con- 
densed in the districts of separation. 
It must be, of the whole mass, Jupiter— 
Saturn — ■

The exterior system- 
29*6 x 172 x 1*21 x 1*05 
The interior system— 
777 x 1-72x1-05. 
The mass, not of Saturn, but of its whole complicated 
system, has retained mass at the expense of the exterior 
and the interior system, whereby the elongation of Saturn 
is somewhat smaller. 
If we then divide the mass logically in 680 parts, the 
system of Jupiter contains 442 parts, Saturn 131, the ex- 
terior system 104*2, the interior 2*83. 
Or it is not exactly, but pretty near, the mass of Jupiter 
to that of the exterior system, as the square of the mass of 
Saturn divided by the square of that of Jupiter to the mass 
of the interior system divided by that of Saturn. 
Which are the relations of distances in the two separated 
systems ? The points of gravitation are the hinges on 
which they swing. I begin, not quite logically, with the 
interior system, because it is the better known. 
It is projected from Saturn, and re-attraCted by the larger
