Electricity on Metallic Bodies. 271 
These results establish, and, I think, conclusively, that the 
distribution of electricity on conductors in an electric field, 
when the direction of the lines of force is perpendicular to 
their ends, and when the material of the field consists of an 
electrolyte, is generally similar to what is known to be the 
distribution of electricity on conductors in an electric field 
when the material consists of a gaseous dielectric. And the 
relatively great electric density found on the end surface of 
the rhombus would also appear to establish a very close resem- 
blance (of course under the given conditions) between the 
action of the points of conductors in electrolytic and dielectric 
fields respectively. 
In the experiments now to be described, I employed a trough 
305 millim. long, 120 broad, and 128 deep, copper electrodes 
of the same area as the ends of the trough, a 5-per-cent. 
solution of copper sulphate, and a current of one ampere 
flowing for six minutes. 
II. When the direction of the lines of force makes an oblique 
angle with the sides of the metallic conductor. 
In a former paper in the ' Philosophical Magazine,' June 
1881, p. 447, it was shown that when the direction of the force is 
parallel to the plane of the analyzing plate, and perpendicular 
to its ends, the electrification of the same sign is identical in 
area on both sides of the plate; also that when the force makes 
an oblique angle with the plane of the metallic plate, the 
electrification of the same sign differs in area on the sides of 
the plate; and, furthermore, that this difference in area in- 
creases as the plane of the plate approaches a right angle to 
the direction of the lines of force. 
In the annexed table are set out the areas in square milli- 
metres of the electrifications and intermedial spaces, side by 
side with the angle of inclination of the plane of the plates. 
The analyzers employed were plates of fine silver measuring 
67 x 7 millimetres. The expressions "+ side/' "— side" in 
the table refer to the side of the analyzer opposite to the + or 
— electrode respectively.
