I was going to guess (surmise, postulate) that the caps were placed in jars to avoid them creating a spark on board a vessel which carried a large supply of black power and other high explosives.

But then they ran them with coal or oil fired boilers, so what real difference would that have made?

Good question though, Carl.

Well I ran this through my gray matter for 48 hours and barely resisted the temptation of Google.

Never would have guessed Leyden jars. Never. Like others above I was thing jars as packing containers for safety, sparks, humidity, shelf life, and on and on. None of it seemed right though and without EVER seeing any NOS on eBay for capacitors packed in jars in "Naval minty" condition , I knew I was running in the wrong circle.

Unit of measure. Approximately a nanofarad. Whoda thunk it ? Great quiz question, Carl.
