Analysis continued. No contingent of heat could be imparted
to any planet by the parent nebula 126
Only one degree of heat added to the nebula from the
beginning till it had contracted to the density
of 1/274th of an atmosphere 127
Increase in temperature from 0° to possible average of 274°
when condensed to 4,150,000 miles in diameter 127
Time when the sun could begin to act as sustainer of life
and light anywhere. Temperature of space 128
The ether devised as carrier of light, heat, etc.
What effect it might have on the nebula 129
First measure of its density, as far as we know 130
The estimate _too_ high. May be many times less 133
Return to the solar nebula at 63,232,000 miles in diameter 134
Plausible reason for the position of Neptune not conforming
to Bode's Law. The ring being very wide had separated
into two rings 134
Bode's law reversed. Ideas suggested by it 135
Rates of acceleration of revolution from one
planet to another 137
Little possibility of there being a planet in
the position assigned to Vulcan 138
Densities of planets compared. Seem to point to differences
in the mass of matter abandoned by the nebula at
different periods 138
Giving rise to the continuous sheet of matter separating
into different masses. Probably the rings had to arrive
at a certain stage of density before contracting
circumferentially 139
Possible average temperature of the sun at the present day.
Central heat probably very much greater 140
Churning of matter going on in the interior of the sun,
caused by unequal rotation between the equator
and the poles 140
