He places the firft Star of Aries in ^ Aries mth 
7^ 9'. North Latitude. And Tuppoflng the Obliquity 
of the Ecliprick 23^ 29', it will be as Radius to the 
Tangent of 23® 29' : : fb the Tangent of 9 to the 
Sine of 3® 7/^, the difference of Longitude between 
the Star and the Point in the Ecliptick which pad under 
the Colure, at the fame time with the Star ; fo that this 
Point was, Anno 1690 ineunte^ in T 15® 43/ and 
therefore allowing 5'c^^ per Annum^ the Star was under 
the Colure 185'! Years before xht Epocha of the Bri- 
tijh Catalogue, that is, 162 Years before our /Era of 
the Nativity of Jefus Chrift; in which very Year 
Hipparchus began to obferve the Equinoxes recorded 
by Ptolemy^ Lih. III. Cap» i. 
If therefore with Sir w'e add 7® 36^ to the 
Long, of the firfl Star of Aries^ as it was in ibpo, we 
lhall have 36® 27 \ which the Colure moves in 2624 
Years: And deducting 1690 therefrom, we fhallhave 
934 Years before Chrift for the Argonautick Expe- 
dition. And if to 7® 36/ we add 3^ 7^ welliall have 
10° 43 'L that is, 772 Years before thefirft Star of A- 
ties pad the Colure. 
Next let us inquire when the Star in the middle of 
the Back of Aries (v Bayero) pad the Colure. Its 
Longitude Anno 1690 ineunte^ was 9° 48' 35^' of Tau- 
rus, with North Lat. 6° 8' ; but by the foregoing Ana- 
logy, the Point in the Ecliptick, over which the Colure 
pad at the fame time with it, was 2° 40^^ before it, 
that is, in X 5 7® 8^ Now 37° 8' give 2674 Years nearly, 
or 984 Years before Chrid, when that Star was under 
the yLquino(dial Colure, being but half a Century earlier 
than Sir IJaac places the Argonautick Expedition ; and 
diewsthat he took the middle of Aries over which the 
Colure is fuppofed to have pad, to be the middle of the 
Condellation, and not of the Dodecatemorion^ and in fo 
doing,
