A total eclipse of the Moon occurred on June 10, 1816. As observed by Beer and Mädler and others, the Moon completely disappeared. The summer of 1816, be it remembered, was very wet, and probably this had something to do with the Moon’s invisibility at the eclipse in question. On October 13, 1837, there happened a total eclipse of the Moon, of which Sir J. Herschel and Admiral W. H. Smyth have left us interesting accounts.[143] The changes of tint, both as regards times and places on the Moon’s disc, recorded by the latter, are very remarkable. And the tints themselves varied very much _inter se_: The Admiral speaks of “copper,” “sea-green,” “neutral tint,” and “silvery,” as hues visible in one part of the Moon or another, and at one time or another.
