Seite 124 - ... and lest thou lift up thine eyes unto heaven, and when thou seest the sun, and the moon, and the stars, even all the host of heaven, shouldest be driven to worship them, and serve them, which the Lord thy God hath divided unto all nations under the whole heaven.
Seite 133 - Rules to know when the Moveable Feasts and Holy-days begin. EASTER-DAY, on which the rest depend, is always the first Sunday after the full moon which happens upon or next after the twenty-first day of March, and if the full moon happens upon a Sunday, Easter Day is the Sunday after.
Seite 54 - At that period, and for the space of the next hour, instead of an eclipse, or the umbra of the earth being the cause of the total obscurity of the moon, the whole phase of that body became very quickly and most beautifully illuminated, and assumed the appearance of the glowing heat of fire from the furnace, rather tinged with a deep red. The...
Seite 43 - I was astounded by a tremendous burst of applause from the streets below, and at the same moment was electrified at the sight of one of the most brilliant and splendid phenomena that can well be imagined.

Seite 43 - that the corona, as to its brilliant or luminous appearance, would not be greater than that faint crepuscular light which sometimes takes place (sic) in a summer evening, and that it would encircle the moon like a ring. I was therefore somewhat surprised and astonished at the splendid scene which now so suddenly burst upon my view.

Seite 17 - If the orbit of the earth and that of the moon were both in the same plane, there .would be an eclipse of the sun at every new moon, and an eclipse of the moon at every full moon. But the...
Seite 53 - ... call your attention to the fact which I have clearly ascertained, that during the whole of the late eclipse of March 19, the shaded surface presented a luminosity quite unusual, probably about three times the intensity of the mean illumination of the eclipsed lunar disc. The light was of a deep red colour. During the totality of the eclipse, the light and dark places on the face of the Moon could be almost as well made out as on an ordinary dull moonlight night, and the deep red colour where...
Seite 65 - The generality of the lunar mountains present a striking uniformity and singularity of aspect. They are wonderfully numerous, occupying by far the larger portion of the surface, and almost universally of an exactly circular or cup-shaped form, foreshortened, however, into ellipses towards the limb ; but the larger have for the most part flat bottoms within, from which rises centrally a small, steep, conical hill. They offer, in short, in its highest perfection...
Seite 43 - ... phenomenon : and when the total obscuration took place, which was instantaneous, there was an universal shout from every observer, which "made the welkin ring;" and, for the moment, withdrew my attention from the object with which I was immediately occupied.
