 The day was clear and cool in the month of October, with breeze enough to hold the kites firmly at anchor when they were flown.Good connection was made with the ground by laying in a wet place a coil of wire one end of which was secured to the binding post of a galvanometer.The equipments and apparatus at both stations were exactly alike; it was arranged that at precisely such an hour and minute the galvanometer at one station should be attached, to be in circuit with the ground and kite wires.
