*This Discourse came too late to hand, for giving time y notice of this Phænomenon; though nothing be lost by this loss of time, as appears by the Advertisement it self.
I. The first Occultation almost ushers in the Year*: For on January 2. in the morning, the Star called Præcedens illarum quatuor in ala Virginis Austrina; may be covered with the Moons Southern limb. But fearing, that this Appearance will scarce be conspicuous, because the approaching light of the Sun will seize the Star before the beginning of the Occultation, I forbear to calcuate it.
II. The next observable Occultation will be on Febuary 25. a little before 8 at night; the Moon then again covering the same Scar in the Virgins South-wing: For which take this Calculus from the Caroline Tables; wherein I have supputed the Moons visible place to 7 h. 18 m. and 8 h. 18 m. P. M. at Derby, supposing its Longitude to the West from London 5 m. 30 sec. and its Latitude, as I observ'd it, 52 d. 58 m.
