Down-stream from the settling-reservoir, 1,348 quinariae were delivered,—more than we have stated to be the capacity according to the records by 69 quinariae, but less than we have shown was received into the conduit from the settling-reservoir by 1,014 quinariae. The total which was lost between the intake and the settling-reservoir, and below the settling-reservoir, amounted to 2,788 quinariae, which I should have suspected resulted from an error of measurement, had I not discovered where it was diverted.

In the records Marcia is credited with the quantity of 2,162 quinariae. Gauging it at the intake, I found 4,690 quinariae,—2,528 quinariae more than appear in the records.
