The eclipse at Gibraltar.



Men of science hoped at the Eclipse of 1870 to determine the nature of the corona, including beams and streamers; but the clearest possible sky was indispensable for the roper use of so delicate an instrument as the polariscope, and this condition was not accorded at Gibraltar even for a second. A correspondent of The Graphic who viewed the phenomenon from the Signal Station on the crest of the Rock, succeeded in making a drawing of the total eclipse, which drawing we reproduce on page 125. This gentleman, a member of the English Expedition, writes as follows: “An interesting map of the path of the total phase of this solar eclipse is published in the Nautical Almanac Circular. Gibraltar lies south of the centre line of the total phase, and the limit of totality extended about twenty miles south beyond us. The cusps were beautiful at the Station all through, and one feature connected with them which excited my interest greatly from time to time, was the vividly stereoscopic or globular form of the dark moon, as she was gradually advancing to cover up the sun. His disc, on the contrary, appeared to be perfectly flat, and to be throwing a species of rosy light over the eastern limb of the moon, in spite of her dark side being towards us, which displayed, with thrilling sense of proximity, her orange roundness.”
