Mar. 30. 9 h at Nightthc Comet, scen without a Teie (cope, appear-ed no otherwise tban a Star of the 4 th Magnitude : tbrough the Telescope heexceeded even those of the First; but he was very Dark, and in what man-ner lbever we look’d upon him, we could Observe almost no Tail at ali ofhim. He iiad passed onc Degree and an half beneath the Lucida os the Sou-thern Fcot of Perseus ; so that this Star was exactly in the midst of the Cometand the little Star of the Leg of Perseus, marked „ by Bayerus , which then wesaw not but by a Telescope. A Straight Line drawn from one of thefcStars to the other, did almost touch tbe Southern Limb of the Comet, whichbeing transferred upon the Mapofthe Fixd Start, feli upon 18 0 45' of Tau-rus in the Northern Latit. of 9 0 y6L At p h 4^. the Western Limb of theComet touched a Straight Line, drawn tbrough this lefs bright Star of PerseiusSouthern Foot, and tbrough the most Northern of the Hcad of Taurus ; butthat he was already got somewhat nearer to the Lattcr.

Mar. z 1 8 h . in the Evening, the Comet was in a direct Line with the Lu-cida in the Foot of Perseus, and with the most Northern in the Head of Tau-rus ; but he was more than twice as much remoter from the first than theother, and being transferred upon the Map of the Fix’d Stars, he was foundat i5 r . from Gemini, in the Latit. of 8° 49'. During the whole time thatwe could observe him this Nigbt (which was till 10 a Clock) he quittednot this Straight Line, which was almost parallel to the Horizon : notwith-standing that bis own particulas motion stiould raise him a little a bove it; asthe Parallax, on the contrary, fhould sink him beneath it in approaching tothe Horizon. It may be, there was a compenfation made of these two con-trary Motions: poihbly also the effect of both was not sensible.

April 1 . The Comet could not be feen without a Telescope, because theMoon, being very near it, hid him from our sight. But with a Telescopeonly of one foot we discerned him easily enougb, and found that he had pas-sed 45'. beyond the most Northern Star of the Head of Taurus, and that hemust have touch’d it by his Southern Limb; as also that he was Distant i*43 1 , ffom the Star that was nearest to that toward the South ; which is equal-ly Bright, yet not marked by Bayern. This place being transferred upon theMap of the Fixd Stars, we found that he was at i° 30' of Gemini, in theNorthern Latit. of 7 0 44/.

April 2. 8 h . in even, M. Cajßni, having observed the Comet with a Tele-scope of one Foot, which dilcovered j°. found that he was two Deg. andhalf Distant from the most Northern Star of Taurus ; and one Deg. from theStar of the Ear marked ? by Bayerus, and by Tycho called Sequentis LaterisBorei.

Two Lines drawn from the most Northern Star of Taurus, one to the Co-met , the other to the Star that is wanting in Bayern, made a Right Angle •,and the Distance of the Comet to this Angle, was double to that which is be-tween these two Stars. This PUce transferred upon the Map of die Fix’dStars, feil on 2° 48'. of Gemini , in the Northern Latit. of 6 ° 4 o f .

Apr. 3. 9 h . we saw him with the one foot Telescope. He had passed overthe Upper Star of the Ear of Taurus , and he made with this Star the Basisof an Isosceles Triangle, on the Top whereof was the Inferior Star of the
