Tesla's notes were the first time that I encountered the
centimeter/centimetre as a unit of both capacitance and inductance.
I see now the connection with the jar -- one jar is 1000 cm of
capacitance, so that a 1 cm capacitance is a millijar.

Hi:
In his Colorado Springs Notebook, Tesla talks about capacitors,
inductors and RF signals, all with the units of meters.
The capacitors were French Champagne bottles filled with salt
water sitting in a salt water bath.? He used the same bottles as
antenna mast insulators, both at the bottom between metal plates
and at the sides of the mast.

Have you ever had?Vegemite?
An Australian sent me a jar as a gag gift.
It's an acquired taste.?
