Now the wires must not touch each other anywhere, but must be completely separated by the ebonite or sealing-wax.
Have you ever heard, my dear, of the Diathermancy of ebonite?
The bath and its contents are allowed to cool together, so that the ebonite cools uniformly.
The Diathermancy of ebonite, by some incomprehensible process, drove her bewildered mind back on her old companion.
These terminals, as well as the communicating wires, are insulated with ebonite.
The light from M passes through the magnets, and a magnified image of the quartz thread is thrown upon the ebonite screen J.
To use the electrophorus, the ebonite is given a negative charge by striking it with fur or flannel.
A, Fig. 3, circular disk, suspended vertically (made of ebonite or other insulating material).
The points of a row of steel-pointed pins, screwed into a frame of ebonite, can be brought within 1/200 in.
Hard rubber (ebonite), being a non-conductor of electricity, makes the best handle.
