Note 3 — Chapter I · THE NILE
Reading edition
For the purpose of illustration, it is interesting to compare the discharge of the Thames at Teddington:
Cubic Metres per Second.
During June the average discharge for the twenty years ending 1902 was 35
The average in June, 1903, was 178
The discharge on June 21, 1903, was 387
On February 21, 1900, it was 533
And on November 18, 1894 (greatest on record), it was 1,065
I have given the discharge in cubic metres per second, the unit generally in use on the Nile. On the Thames the figures are usually given in gallons per day, which sounds much more imposing. If the number of cubic metres per second is multiplied by about 1,900,000, it gives approximately the number of gallons per day. But, after all, the discharge of the Thames in June, 1903, was not so very far below that of the Nile during the same month.
