<p style='text-align: justify;'>Photograph of the 1897 draft of the introduction to a paper on cathode rays by JJ Thomson. See: Thomson, Phil. Mag., (5), 44, 293, 1897. This is the hand-written draft of Thomson's famous paper on the nature of cathode rays, the first subatomic particles to be discovered. The published version is essentially identical to this draft. The writing is not Thomson's but the notes were added by him.</p>
