Etymology

Example Sentences

• "Lunar eclipſes are not quite ſo complicated in theory, nor near ſo tedious and difficult in calculation, as ſolar ones. The latter are only apparent, the former really ſuch; that is, the Moon is really deprived of its light, and therefore muſt appear obſcured to all the inhabitants of the earth equally, by whom ſhe can be ſeen; whereas the Sun, not being deficient in light, will ever appear reſplendent to thoſe who do not happen to live on that part of the earth where the lunar ſhadows pass."
