By a trigonometrical calculation, I find that the sun rose 
centrally eclipsed in S. lat. 5 0 g' and E. long. o° 4 6'. The 
moon’s umbra then passed over the continent of Africa in a 
north-easterly direction ; and, crossing the Red Sea, entered 
Arabia near Mecca, continuing its course over the provinces 
of Kerman and Segistan in Persia. The sun afterwards be- 
came centrally eciipsed on the meridian in N. lat. 33^-° and E. 
long. 68°. Consequently this eclipse could not be central in 
any part of Asia Minor : and yet it has generally been consi- 
dered, of late years, as the only one that could be reconciled 
to the fact. 
Lastly, I shall notice the eclipse proposed by M, Volney, 
which happened February 3d, 626 B. C. The ecliptic con- 
junction took place at 4 11 ig' 27" in the morning, mean time at 
Greenwich, or 4/ 1 o' 35" appamit time : and the elements were 
as follow :
