1868 Transit of Mercury seen from Liverpool with a Cooke.
George Williams using a 4.25 inch Cooke & Sons telescope observed the transit of Mercury on November 5th 1868 from 2, Devonshire Road, Prince’s Park, Liverpool.
Williams observed no apparent elongation or pear shape, or black drop at the egress of the planet; but the boiling of the limb, which was considerable, may account for the absence of these appearances.
