    Object history
    At the meeting of the Royal Society on 4 January 1665, ‘Mr. Francis Willughby being come home from his travels, and present, was desired to communicate his philosophical observations made abroad. He produced a printed cut representing Saturn and Jupiter, and what Campani had lately observed in them by the means of his new glasses, wrought by a turn-tool without a mold, viz. that July 30 h. 2 ½ noctis, he had seen in one of the black belts of Jupiter two blacker spots, moving therein, which Signior Cassini had first given him notice of, conceiving them to be the shadows of the Satellites, which he had seen come out of the western disk of the planet. Mr. Willughby was desired to communicate to the society, at the next meeting, the other observations and collections, which he had made in his travels’ (Birch 2:3).
