Separated Materials

MSSW-13 is a notebook of experiments on plant-based photographic emulsions, later published as On the Action of the Rays of the Spectrum on Vegetable Juices. Hidden inside were eleven small paper strips with coloured emulsion painted on. These are light sensitive and so were removed. They are now stored seperately as Dep. c. 354*.
