I received it. It appears then that nobody is posting anything.
I will post then:

After having made several dozens of electrostatic machines and other
high-voltage generators, I still thing that the most interesting of
these devices is also one of the simplest, oldest, and less known
of the influence machines, the "doubler" invented by Bennet in 1787:

Very few books even mention it, and except for the ones that I have
made, I don't know of other reproductions. It's a funny device, much
better than a basic electrophorus as static electricity generator.
