9059. WEATHER, Moon and.—

I do not
know that the coincidence has ever been remarked
between the new moon and the greater
degrees of cold, or the full moon and the lesser
degrees; or that the reflected beams of the moon
attemper the weather at all. On the contrary,
I think I have understood that the most powerful
concave mirror presented to the moon, and
throwing its focus on the bulb of a thermometer,
does not in the least affect it.—
