10.  See again another evident proof of its greatness.  Although the heaven may be full of stars without number, the light contributed by them all could not disperse the gloom of night.  The sun alone, from the time that it appeared on the horizon, while it was still expected and had not yet risen completely above the earth, dispersed the darkness, outshone the stars, dissolved and diffused the air, which was hitherto thick and condensed over our heads, and produced thus the morning breeze and the dew which in fine weather streams over the earth.  Could the earth with such a wide extent be lighted up entirely in one moment if an immense disc were not pouring forth its light over it?  Recognise here the wisdom of the Artificer.  See how He made the heat of the sun proportionate to this distance.  Its heat is so regulated that it neither consumes the earth by excess, nor lets it grow cold and sterile by defect.
