This brings up the question of possible motors, and ifwe confine ourselves for the present to 25 miles per hour,and assume the power required at 10 H P, per ton of ap-paratus, we see at once that only a fraction of that weightcan be devoted to the motor. Let us assume, and I thinkthis is not far wrong, that only one-quarter of the weightcan be apportioned to the motor and its supplies ; the re-maining three-quarters being required for the weight ofthe framing, the aeroplane surfaces, the various appurte-nances, and the aeronauts, we then have but = .1 4 X 10 Vol. LXIV.
