Throughout each experiment the pressure of the air in the bell-jar was kept constant by regulating the stop-cock, C, so that the abstraction of air by the pump was exactly compensated by the gain through C. Fig. 13. The galvanometer measures only that part of the electricity entering the bell-jar by the wire, ww, which leaves it by its metal base. This part is very nearly the whole. The observed results show that it is enormously great in comparison with the very small part which is carried away ki the current of air to the electric filter. The galvanometer was shunted by a battery of Leyden jars, J, to give steady deflections. Its sensitiveness was l/22-l of a mikro-ampere per scale division. 83. First, we kept the potential of the needle constant throughout a set of experiments made at different air-pressures, and in this way we found that the current through the air to the metal of the jar became greater as the pressure of the air in the bell-jar became less, down to the lowest pressure to which we went, which was 40 millims. Curve 10 shows the relation between the current and the air-pressure at a potential of 5000 volts. Similar curves were got for other electric potentials. 84. We found also that as the air became rarer it was not so much electrified. This was shown by the electric filter and electrometer. Thus the electrometer deflection for a pressure of 360 millims. was only about one-sixth of that for 760 millims. with the same number of strokes of the pump, and the same potential of the electric machine. Curve 10. 85. We next kept the pressure of the air in the bell-jar constant and v...
