This is an example of a cylindrical Leyden jar, used by Marconi during his early experiments in the development of the tuned transmitter. A Leyden jar is a device that early experimenters used to help build and store electric energy. It was also referred to as a 'condenser' because many people thought of electricity as fluid or matter that could be condensed. Nowadays someone familiar with electrical terminology would call it a capacitor.
