Hipparchus exprefsly fays, that It rofe when 23 
Degrees of Sagittary * was on the Meridian, and 
fet when 29 Degrees of Gemini pad it; and ta- 
king the middle between thofe Points, it is plain, 
that it culminated with about 26 Degrees of Pifcesy 
and that it had North Declination,* the Excefs above 
I So Degrees iliewing that the Afcenfional Difference 
was about 2 | Degrees. But to give the Argument 
its full Scope, the Right Afcenfion of 23 t of Sa- 
giftary fallowing Hipparchus his Obliquity 23® 51' 
w’ill be found 262^ 5-4'. And that of 29 De- 
grees of Gemini will be 88^ 54^ : So that this Star 
was above the Horizon ( in the Latitude of 35 De- 
grees North ; to which Hipparchus has adapted his 
Calculation^ 12 Hours 24 Minutes or 186 Degrees,* 
whence the Right Afcenfion of the Star is juffly 
concluded 3 5' 5- Degrees 5*4 Minutes ; and its Afcen- 
fional Difference precifely 3 Degrees ; which in that 
Latitude makes its Declination 4 Degrees 7 Minutes 
North. We have therefore gotten both the Right A- 
fcenfion and Declination of this fuppofed firff: Star of 
ties. 
Let us now fee what Longitude and Latitude re- 
fults from the aforefaid Right Afcenfion with 4 De- 
grees 7 Minutes North Declination, affuiiiing the Ob- 
liquity with Hipparchus^ to have been 23® 51^ 20^' 5 
• and we fliall by a juft Computation, find the Star at 
that time to have been in 27® 53' of Pifces^ with 
5^ 24/ North Latitude, which therefore was reckoned 
the place of the Star at that time by Hipparchus, 
Add 2®. 40', for 265 Years between Hipparchus and 
Ptolemy^ and we ihall have its place, in Ptolemy s 
Account, Aries 33', with 5*? 24' North Latitude. 
But the lid Star of Pifces in Ptolemy s Catalogue has 
the fame Longitude and Latitude, with iufficient ex-
