Thus the coefficient of theoretical expenditure due to the work, duringthe experiments on the turbine which I constructed at Bourges, has been found very little different fromthat which agrees with the openings of ordinary sluices disposed so as to avoid contractions on three ofthe sides. The wheel which turned in work, with about half the velocity due to the fall, and the co-efficient, was 0-70 to 0-79. M. Poncelet, adopting an arrangement the reverse of that of M. Fourneyron, has proposed a systemof turbines of the nature of the horizontal wheels used in the centre and south of France. The waterenters by a spout placed on the outside, s
