 west; and this one from the satellite further to the west 6′. In magnitude they were nearly equal; the satellite nearest to Jupiter was rather smaller in appearance than the rest. But at the seventh hour (Fig. 36) the eastern satellites were at a distance of only 0′ 30″ apart. Jupiter was 2′ from the nearest satellite on the east; and from the satellite on the west, next in order, 4′; this one was distant 3′ from the satellite further to the west. They were all equal in magnitude, and in a straight line, drawn in the direction of the ecliptic.

Feb. 5.—The sky was cloudy.

Feb. 6.—Two satellites only appeared, with Jupiter between them, as is seen in the accompanying figure (Fig. 37). The satellite on the east was 2′ from Jupiter, and that on the west 3′. They were in the same straight line with Jupiter, and were equal in magnitude.

Feb. 7.—There were two satellites by the side of Jupiter, and both of them on the east of the planet, arranged in this manner (Fig. 38). The intervals between the satellites and Jupiter were equal, and of 1′ each; and a straight line would go through them and the centre of Jupiter.

Feb. 8: 1h.—Three satellites were there, all on the east side of Jupiter, as in the diagram (Fig. 39).
