232 Mr. Baily on the Solar Eclipse 
is scarcely necessary to add, that this eclipse likewise was 
annular. 
In the eclipse alluded to by Usher, September 20th, 601 
B. C. the ecliptic conjunction took place at j h 25' 18" in the 
morning, mean time at Greenwich, or 7 h 31' 35" apparent lime :

From a projection of this eclipse, it will be seen that the 
centre of the moon’s shadow entered the earth’s disk very 
near the north pole; and that the sun became centrally eclipsed 
on the meridian in N. lat. 73I 0 and in E. long. 72 0 10k The 
umbra then passed over Siberia and the eastern parts of the 
Chinese empire : and consequently this eclipse was not central 
in any part of Asia Minor. 
The eclipse first suggested by Bayer, and hitherto gene- 
rally received as the true one, happened May 18th, 603 B. C. 
The ecliptic conjunction took place at 7 h 12' 13" in the morn- 
ing, mean time at Greenwich, or 7 h 19' 36" apparent x time :
