Description
Three figures showing lighting effects in a vacuum tube during experiments conducted by William Crookes. The ‘Crookes Tube’ was a glass container through which high voltage could be applied within a partial vacuum. It was a type of cathode ray tube, projecting what J.J.Thompson (1856-1940) would later characterise as electrons. In the paper associated with this illustration, Crookes suggested that: “The phenomena in these exhausted tubes reveal to physical science a new world – a world where matter may exist in a fourth state…”, what would now be termed plasma.

Sir William Crookes (1832-1919) chemist and science journalist was elected a Fellow of the Royal Society in 1863. He served as President of the Royal Society 1913-1915.
