There may be much light and heat radiated by a spot, which seems totally black
as compared with the sun : we remember that when we look through even a
Drumrnond light at the sun, it appears as a black spot on the disk of that luminary.

Their motion being stopped and changed to heat, feeds this great central fire.
Were Mercury to strike the sun in this way, it would generate sufficient heat to
compensate the loss by radiation for seven years. Many suppose that the heat of
