AN UNUSUAL VICTORIAN ‘CROOKES’ TUBE

comprising a clear glass tube containing white metal Maltese cross filament, mounted on beechwood stand, 25cm high x 29cm long

Note: Circa 1869, a team of scientists led by English physicist William Crookes invented the Crookes tube, an early experimental electrical discharge tube with a partial vacuum. This device led to the first observation and discovery of cathode rays.
