194 PROFESSOR G. B. AIRY ON THE ECLIPSES 
Baily and Oltmanns, is now thrown north even of the sea of Azov. I have likewise 
formed the first approximate elements of the eclipses from b.c. 630 to b.c. 0 / 6 , by 
the use of M. Largeteau’s very convenient tables inserted in the Additions to the 
Connaissance des Temps, 1846, and am led to the same conclusion. 
38 I shall now proceed with the computation of the eclipse of b.c. 080 , iMay 28. 
The elements are formed precisely in the same manner as those for the eclipse of 
Agathocles. The following are the primary numbers for the moon, for -o84 (or
