§. XXXIV. Their Observations.To their Experiments I will subjoin their Observations, which differ but in name from the other, the same fidelity and truth being regarded in collecting them both.
Observations of the fix'd Stars for the perfecting of Astronomy, by the help of Telescopes: of the Comets in 1665 and 1666, which were made both in London, and elsewhere; and particularly of the first Comet, for above a month after it disappear'd to the naked eye, and became Stationary, and Retrograde.
Observations about Saturn, of the proportion, and position of its Ring, of the motion and orbit of it Lunale, of the shadow of the Ring on the Body, and of the Body on the Ring; and of its Phases, &c. of Jupiter's Belts, and of its spots, and verticity about its Axis, of its eclipsing its Satellites, and being eclips'd by them; of the Orbs, Inclinations, Motions, &c of the Satellites, together with Tables, and Ephemerides of their motions.
Observations of the Spots about the Body of Mars, and of its whirling motion about its Center: of several Eclipses of the Sun and Moon, and some of them as were not taken notice of by Astronomers, of Tables commonly used: of the Spots in the Moon, and of the several appearances in the Phases of it: of the Moon at the same time, by Correspondents in several parts of the World, towards the finding her Parallax, and Distance.
