Syftem of Chronology. What he faith, concerning 
the Epocha of th e Argonauts, is founded on the Sup- 
pofition that I place the Equinox in the lime of the 
Argonautic Expedition, fifteen Degrees from th: firft 
Star of Aries , Pag. 75, 79. I place it in the Middle 
of the Confteilation, and the Middle is not fifteen 
Dergees from the firft Star of Aries. The Obferva- 
tor grants that the Conftellations were formed by 
Chiron (Pap. 70, 71, 79.) and that the Solftices and 
Equinoxes were then in the Middle of the Conftei- 
lations (Pag. 65, 69, 75.) and that Eudoxus, in his 
Enoptron or Speculum cited by Hipparchus, followed 
this Opinion, Pag. 62, 63, 6 5, 69, 79. And * Hip - 
parchus names the Stars, through which the C'olures 
paffed in this old Sphere, according to Eudoxus , and 
faith exprelly that Eudoxus drew one of tliefe Colures 
through the Middle of Cancer and the Middle of Ca- 
pricorn , and the other through the Middle of Chela and 
the Back of Aries. And the Colurus, patting through 
the Back of Aries, paffes through the Middle of Aries* 
and is but eight Degrees from the firft Star of Aries. 1 
follow Eudoxus , and, by doing fo, place the Equi- 
noctial Colure about 7 gr. 36' from the firft Star of 
Aries. But the Obfervator reprefents, that I place it 
■fifteen Degrees from the firft Star of Aries , and thence- 
deduces that I fhould have made the Argonautic Ex- 
pedition 532 Years earlier than I do. Let him reftify 
his Miftake, and the Argonautic Expedition will be 
where I place it. 
As for the Length of Generations , the Obfervator 
faith, that I reckon them one with another at 18 or 
20 Years a piece (i’ag. 52, 55 -) which is another
