 of 6′ from Jupiter. Jupiter was 4′ from the nearest satellite on the west; between this satellite and the satellite further to the west there was an interval of 8′; they were in the same straight line exactly, and were nearly of the same magnitude. But at the seventh hour four satellites were there—two on each side of Jupiter (Fig. 33). Of these satellites, the most easterly was at a distance of 4′ from the next; this satellite was 1′ 40″ from Jupiter; Jupiter was 6′ from the nearest satellite on the west, and this one from the satellite further to the west, 8′; and they were all alike in the same straight line, drawn in the direction of the Zodiac.

Feb. 3: 7 h.—The satellites were arranged in the following way (Fig. 34):—The satellite on the east was at a distance of 1′ 30″ from Jupiter; the nearest satellite on the west, 2′, and there was a long distance, 10′, from this satellite to the satellite further to the west. They were exactly in the same straight line, and of equal magnitude.

Feb. 4: 2 h.—Four satellites attended Jupiter, two on the east and two on the west, arranged in one perfectly straight line, as in the adjoining figure (Fig. 35). The satellite furthest to the east was at a distance of 3′ from the next satellite. This one was 0′ 40″ from Jupiter; Jupiter 4′ from the nearest satellite on the
