Abstract
LORD RAYLEIGH mentions (NATURE, Oct. 27) that celluloid containing malachite green changes to a red colour when exposed to sunlight. He rightly remarks that this change is caused by the nitrocellulose and not by the camphor present in the celluloid. Bertholet and Gaudechon (C.R. 153, p. 1220; 1911) found that oxides of nitrogen are liberated when nitrocellulose is exposed to ultra-violet light. It has also been known for some time that solarised nitrocellulose becomes acid.
