numbers in solutions of acetic acid (up to the present no similar mea- 

 eurements have been made with any of the weaker acids) give results 

 which are totally at variance with these assumptions, and which may 

 throw light on discrepancies observed elsewhere when the theory of 

 electrolytic dissociation has been pushed to extremes. 



9. Tlie Ferrous Sulphates and their Hydrates: — Dr. F. B. Ken- 

 rick. A study of the system FeO, SO^, H^O, from the point of view 

 •of the Phase Eule, leading to a systematic cataloguing of the various 

 ■hydrates and acid salts, and a determination of the conditions under 

 which they can exist. When working with solutions in concentrated 

 sulphuric acid, it was found impossible to dry the crystals without risk 

 ■of decomposing them, but by dissolving ammonium sulphate in the 

 mother-liquor, and determining ammonia as well as iron and sulphuric 

 ■acid, the amount of mother-liquor adhering to the crysitals could be 

 ascertained. 



10. The bactericidal action of solutions of Phenol containing salts, 

 and the chemical potential of Phenol in the solutions: — Prof. W. Lash 

 Miller and Prof. J. J. MacKenzie. Solutions of various quantities of 

 Phenol and salts in water were shaken with Toluene and the distribu- 

 tion of the Phenol between the two solvents determined. The rate 

 at which Anthrax spores die in the same solutions was then determined. 

 The rate seems to be the same in all solutions that are in equilibrium 

 with the same solution of Phenol in Toluene, and is increased by in- 

 crease in the concentration of either Phenol or sodium chloride. The 

 experiments are not yet finished. 



11. A convenient integral form of the Equations of Chemical 

 Kinetics: — Prof. T. R. Eosebrugh and Prof. W. Lash Miller. A partial 

 abstract of the contents of this paper is contained in " Numerical values 

 of certain Functions involving e^ " appearing in the present volume 

 of these Proceedings.
