At least twelve or thirteen minutes must have elapsed, when, accidentally turning to Jupiter again, to my astonishment I perceived the same satellite outside the disc ! It was in the same position as to being in a line with the apparent lower belt, where it remained distinctly visible for at least four minutes, and then suddenly vanished.
