ELECTRIC DISCHARGE WITH THE CHLORIDE OF SILVER BATTERY. 513 
Another tube was made to test whether there is a current at right angles to the 
column of gas; namely No. 366, 2 If inches (54'61 centims.) long, and If inches 
(41 centims.) in diameter, in it are sealed five idle wires, 1, 2, 3, 4, 5. No. 3 is 
5 \ inches (14 centims.) from the positive. Nos. 3, 5, 1 are all in a longitudinal line 
on the same side of the tube, 4 and 2 in line on the opposite side; 4 is diametrically 
opposite to 3, 2 diametrically opposite to 1. The tube with its wires is shown in 
fig. 30, 1, 2, 3 ; the opposite wires of the galvanometer are marked a and b.

The charge was hydrogen, and 2400 cells were used. In the first place the galvano¬ 
meter was connected with two wires in a longitudinal direction, the galvanometer 
wire b to the idle wire 5, the galvanometer wire a to the idle wire 1 ; the idle wires at 
this time straddled both 
amounting to : — 
stratum and a space. The

The wires of the galvanometer were now reversed, a to 5 and b to 1, the deflection 
was now to the left, but the galvanometer connexion having been reversed, the sign 
was the same as in the preceding.

All these deflections are in the same direction as if the current went through a wire. 
The wires of the galvanometer were now connected, b to 1, a to 2, these being
