From the comparative observations made during the French expedition, Girard calculated that by the Nile alluvia the soil was raised on an average about 5 inches in a century. Hence, notwithstanding its slight encroachments seawards, the level of the delta would have been raised about 20 feet during the last five thousand years, that is, since the Egyptians had already
