486, Phamenoth (VII) (p. 232. B. vol. 2. p. 169. H.) In the 

 23d year of Dionysius, the 4th of Tauron, in the evening. Mer- 

 cury was at the distance of 3 moons from the line drawn 

 through the bull's horns, or in B 23° 2' ; the year being the 

 486th of Nabonassar : the mean sun being in cyD 29 J° : the 

 time was "Phamenoth, the evening of the 30th to the 1st:'* 

 this must have been the evening between the 30th of Mechir 

 and the 1st of Phamenoth, in order that the sun's longitude 

 may have been less than 30° : or 0— 26iy + 31.6^ 



486, Payni (X) 30. (p. 232. B. vol. 2. p. 170. H.) In the 24th 

 of Dionysius, the 28th of Leonton, in the evening ; Mercury 

 preceded Spica, according to Hipparchus's reckoning, a little 

 more than 3° ; being in 19J° of iij?. ^-2613' + 151.6*. 



491, Pharmuthi (VIII) 5. (p. 232. B. vol. 2. p. 169. H.) In the 

 28th year of Dionysius, the 7th of Didymon in the evening.

504, Thoth (I) 27. (p. 232. B. vol. 2. p. 171. H.) In the 67th 

 year according to the Chaldeans, on the 5th of Apellaeus, Mer- 

 cury was in in 2° 20' : this was the 27-8 of Thoth, 504 N. 

 towards the morning. ^ — 243y — 125.55**. 



Hence the first Chaldean year must have been the 438th of 

 Nabonassar. Apellaeus is the second of the Macedonian months ; 

 and if Dius the 1st had 30 days, this Macedonian year must have 

 begun about 159 J days before the vernal equinox, if 29, 158 J.
