Abstract
IN the preparation of some tungsten compounds I obtained a by-product which is reduced on exposure to sunlight, the reduction being marked by a change of colour and being accelerated by reducing agents. In the dark, in contact with the atmosphere, the original colour is gradually restored. The same effect is brought about instantaneously by oxidising agents. Will readers of NATURE who are acquainted with reactions of a similar type kindly inform me of publications on the subject?
