The maddening influence of moonlight was commented upon, as if it were a fable; but WILLIAM STORY said it was a fact. In tropical regions very sad consequences resulted from long gazing on the moonlight or sleeping in it. In one town he had known sixteen persons bewildered in this way. WILLIAM WHITE said that in a late book of Nichols it was contended that the moon had some light of her own, because she shows a brazen color even under eclipse, when the dark side of the earth is toward her. But why may she not gather stellar light from the whole universe, as the earth seems to? SALLIE GARDINER said something to William Story in a low voice. He laughed, and said he had been thinking of the consequences of his theory. MARGARET asked what he was talking about. STORY said it was an application of eclipses to his theory that love was the motive to creation. If the sun is beneficent truth shorn of its beams, it would be like the moon, no better than brass! CAROLINE STURGIS asked why the Mahomedans bore the crescent. WILLIAM WHITE said because of some change in the moon which occurred at the time of the Hegira. WILLIAM STORY said that the worshippers at Mecca carried the crescent before Mahomet’s time. There is a crescent on the black stone. Both stories may be true. There is certainly a crescent on the old Byzantine coin, or besant. IDA RUSSELL said something about Diana being wedded. This reminded E. P. P. of Minerva’s marriage, discussed last week. She said that Charles Wheeler had seen the gem of which she then spoke, and that Neptune was the favored suitor. WILLIAM STORY said the Greeks could not wed Neptune to Diana, for the tides were too low in the Mediterranean! C. W. HEALEY. April 10, 1841. VII. PLUTO AND TARTARUS. _April 15, 1841._ MARGARET said very little about Pluto. On the first evening she had called him the depth of things, and JAMES CLARKE now had a good deal to say upon the three ideas which she thought pervaded the Greek mythology,—the source, the depth, and the extent or flow of thought. He said that this distinction had struck him very forcibly when Margaret first mentioned it. We speak of widely diffused thought, of aspiring and profound thought; of sympathetic, exalted, or deep feeling,—and this seemed to exhaust language. It was through the depths of feeling and experience that we came to the profound of thought. E. P. P. said, “There is no genius in happiness.” Not a very intelligible statement. MARGARET said, “There is nothing worth knowing that has not some penalty attached to it. We pay it the more willingly in proportion as we grow wise. Depth, altitude, diffusion, are the three births of Time. It is this which makes the German cover the operations of the miner with a mystic veil. Bostonians laugh at the Germans because they think.”
