Procopius, in his firft book, I think, fays, that 18 peeks was too full a Nile, and occafioned dearth by its quantity. But, in the middle of the 6th century, he tells* us it requi- red 18 cubits for a minimum, by which Egypt was to pay the meery; fo that in 100 years from Julian to Juftinian, the minimum had increafed three cubits, which was 4I feet ; not one foot in 100 years as the propofition bears ; and this would prove too much, if it was true, but it is impofli- ble.
Thus far, then, we are at liberty to fay, that, as long as Egypt was a Greek kingdom, no vifible alteration or in* creafe of the foil can be fairly eftablilhed from hiftory or infpeclion.
