are more conversant with, and better informed on, the sub- 
ject: and I regret that I have not more time to pursue the 
inquiry farther. 
Such an alteration, as is here suggested, would somewhat 
vary the position of the route of the moon’s umbra, in all the 
eclipses which have been the subject of this paper; but, in 
none of them would it alter the conclusions which have been 
drawn from them, except perhaps in the one (Sept. 30th, 6 10 
B. C. ) which I have supposed to be that mentioned by Hero- 
dotus. In this particular case, the path of the moon’s umbra 
might, by such a correction, be thrown so much farther north 
as to prevent the eclipse being total in any part of Asia Minor. 
But still it would remain the only one that can be at all adapted 
to the account given by Herodotus ; since there is no other 
that could possibly be central in, or near, any part of Asia 
Minor from the year 650 B, C. to 580 B. C. : a period which 
far exceeds the probable limits of time wherein this singular 
phenomenon must have taken place, so as to be reconcileable 
to any received system of chronology.
