1. Titrations of wool with hydrochloric acid in the presence of sodium chloride, sodium sulphate, potassium chloride, potassium sulphate, and barium chloride, and with sulphuric acid in the presence of sodium chloride and sodium sulphate, have been performed, the absorption of hydrogen, chloride, and sulphate ions being determined. 2. The presence of sulphate ions always gives greater absorption of hydrogen ions than does that of chloride ions. 3. A critical review of absorption theories is given, as regards their value for interpreting the experimental results. 4. Both the Gilbert‐Rideal and the theories are used for accurate comparison with the experiments; the former gives quite satisfactory results, but the latter gives only qualitative agreement. 5. It is concluded that chloride and sulphate ions are not dispersed at random in the fibre phase, but are to some extent localized at positive sites, the former having greater affinity for the wool fibre than the latter ions.
