(1) Coated glass tube of about 1/2 an inch in diameter with tin foil, sent shock from jar without knob through the tin foil, while a wire as shown in the figure made a current. found a secondary current in this way. [[smaller text]] Repeated this again, wire at right angles to the tube. [[/smaller text]]

The direction of this current was the same as that in the experiment of two parallel wires, namely with a very small charge the needles were magnetized --, with larger charge +, and still larger o.
The hole in a card was nearer the minus pole, but near the middle of the distance between them.

(2) Tried to get a spark with the same arrangement by means of snaps from the conductor increased by the large plate attached, found a feeble spark. Needle very feebly magnetized +. The current in this case is combined with the induction from the inside of the tube, the wire acting as coating, hence the electricity will tend to be thrown off in each direction.

This experiment (1) has a bearing on the experiment in which the electricity was shown to pass on the surface of a conductor. The feeble current in which I obtained in one experiment was probably due to induction.

In the experiment of the electricity passing over the surface, use a very short tube, so that the induction may be small.

Placed small needles, made of knitting needles 5/8 of an inch long, and 1/36 of an inch in diameter on each side of a slip of tin foil [[underline]] a [[/underline]]. sent charge from battery through the foil, examined the needles, found them unmagnetic. This experiment belongs to those on the passage of electricity through a plate.
