Grey cotton has been padded in aqueous solutions of caustic soda and thin staamed in a standard laboratory apparatus. Determinations have been made of the proportion of organic material removed from the cotton and of the solvent‐extraotable material remaining in the cotton after treatment. The effects of chemical pretreatment of the cotton, concentration of alkali, time of steaming, and the presence of auxiliary substances on these quantities have been studied.
