[78] It must be recollected, to account for the greater quantity of matter between the cesspools of Paris and London, that the French fixed cesspool, from the greater average of inmates to each house, must necessarily contain about three times and a half as much as that of a London cesspool. If the dwellers in a Parisian house, instead of averaging twenty-four, averaged between seven and eight, as in London, the cesspool contents in Paris would, at the above rate, be between four and five tons (as it is in London) for the average of each house.
