with a Telefcope only of one foot we difccrned him cafil jr enough, 
sfnd foiincl,that he had paffed 45'. minutes beyond the moft Nor* 
thern ftar of the Head of tmruiy and that he muft have touch't it 
by his Southern limb \ as alfo that he was diftant one degree and 
43'.from the Scar that was neareft to that toward the South. This 
place being transferred upon the Map of the fixt fears, we found, 
tiiat he was at i .deg. and 3.0'. of Gemmi^in the Northern Latit. of 
7 deg. 44'. 
Signor CaJJini^hdiVmg confidered thefe two ftarSyObferved^ that 
the fecond is not iefs bright than the tirft ; and yet that Bayerus 
hath not marked it, who hath made an exa(ft enumeradon of the 
Stars that may eafily be feen with the naked eye ; and that at firfk 
^ight it feems,rhat Tycho hath left it out in his Catalogue. For he 
puts 4 ftars in the place he calls m qudi^riUtero cer'uicUy. and he 
fpeaks notof this which is the 5 th, and maketh with the other 
four an-irregular pentagone. 'Tis true,that befides thefe 4 ftars,. 
after he hath marked 1 3 others of thcm^ he puts yet one by it feif 
for the laft,which he calls w quAJiriUtero colli fracedens \ as if, be- 
fides the firft quadrilateral, there were yet another in the Neck of 
tmrds. Mean time there is in this place but 5 ftars of the 5th 
magnitude, which make not a quadrilateral figureibut a pentagone^ 
as I was juft now faying. 
Thisomiflionof jB;?/fr/i^, and the denomination, which Ijy^r/^o^ 
ufeth to denote thefe Stars, which fuits not with the number nor 
the configuration that now appears,do adminifter caufe to doubt,, 
whether the Star in qUeftion be not cne of thofe that appear fi^om 
time to time;as there arc two in the conftellation of the 6W;?^nd 
another in the neck of the Whde. We fhall particularly take 
heed of this place of the Heavens,to clear up this doiibr. 
Jfril 2. h. 8. in the even, Signor CaJ/ini^ having obferved the 
Comet with a Telercopc of one foot>wh.ch difcovered 5 degrees^ 
found, that he was two degrees and an half diftant from the mofl: 
Northern ftar of Taurus; and one degree from the ftar of the 
Ear, imrked (p by Bdyeru^, ^nd by Tycho ca! *ed fequentis UterU 
Bored. 
Two ririCs drawn from the moft Northern RdiY of Taurus ^ one to 
the Comer,thc other to the Star that is wanting in Bayems^ made a- 
right angle'; and the diftance of the Comet to this angle was 
double to tha^t,which is between thefe two Stars.This place tranf- 
ferred upon the Map of the fixed Stars, fell on 2 degrees and 48'. 
of G^ww,in the Northern latit;. of 6. deg. and 40'.
