pressed against the re-attradting yet decreasing force of the 
Sun, and against the central aphelion; their density decreases 
with elongation.

The densities are therefore — that of the Earth, 1 ; the Sun,

Proceeding to the velocities of rotation, I begin again with 
the inner system. Rotation of the point of gravitation of 
the central mass was 68*5 times more rapid than that of the 
Sun. As the mass now proceeds from the aphelion it moves 
2*95 times more slowly, but by the elongation it experiences 
1*21 more rapidly. The point of gravitation at 176 from 
the Sun would therefore have a rotation — 
68^XT22 = 28 . I 
2*96 
more rapid than that of the Sun. 
The velocity increases inversely as the square of the 
single elongations increases. We have for —

A difference there is with Mercury, whose day is 26 h. 26 m., 
whereas observation has adopted 24 h. 5 m. 
The separation of the inner system resulted by a more 
rapid transport ; it may be considered as resulting from a 
shock, the line of planetary development experienced between 
G and 7 in the sense of the whole transportation (designating
