ELECTRIC DISCHARGE WITH THE CHLORIDE OE SILVER BATTERY. 505 
In the following experiments the arrangement I. was employed, that is to say, the 
poles of an insulated battery were connected with the terminals of the tube, and an 
earth connexion made either by means of a stout or fine wire to the negative terminal. 
Air was introduced, and at various pressures, with 2400 cells, the following results 
were obtained: —
