on ascending so, as to pass the Æquinoctial, and perhaps proceed to 15. degrees Northern Declination, if it do not disappear before that time, by reason of its remoteness: Nor to believe, that there have been two Comets, upon its being seen again the 31 of December; since, according to him, it ought to have been so, if it continue to move in a Great Circle.

Having hereupon shewed, how the motion is to be traced upon the Globe, he finds, that, according to his Calculation, this Comet was to pass the Tropick of Capricorn about the 16 of December, and being entred into the Sign of Virgo on the 20. of the same month, and having been in Quadrat with the Sun, it should still descend, until the 26 of December in the morning, and then enter into Leo; that having entred, the 28. of the same month, into Cancer, and been, a little after that time, in its greatest Inclination to the Ecliptick, vid. in the 28. degree of Leo, it was to repass the Southern Tropick, over against the little Dogg, on the 29. of December about 9 or 10 of the clock in the morning; after it had been opposite to the Sun 2. or 3. hours before; and that on the 29. of December in the evening it should be in Gemini; and at the very beginning of the New year, enter into Taurus.

After this, our Author finds, that this Comet according to his account, should pass the Æquator, on the 4. of January before noon, and that about 5. or 6. of the clock in the evening of that day it was to come into the jaw of the Whale, and the 9. of the same, at 6. of the clock, it should come close to the small Star of the Whale, which is in its way, a little below. At length he finds that it was to enter into Aries on the 12. of January, and to cut the Ecliptick on the 16. of the same month about noon, at which time it was to be again in Quadrat with the Sun, whence drawing a little to above the Northern Line of Pisces, it should in his opinion cease to appear a little beyond that place, without going as far as to the middle of Aries, if so be that its remoteness make it not disappear sooner.

He continueth, and saith, that this Comet shall not arrive to the place over against the Line of Pisces till the 10 of February, & that then its Diurnal motion shall not exceed 8 minutes, and not 5 minutes about the 20 of the same month: and that in the be-
