[MILLER] RESEARCHES IN PHYSICAL CHEMISTRY 27 
the anode contains cupric and cuprous salt in the proportions in which 
they are in equilibrium with metallic copper. 
14. C. C. Forward: The electrical conditions under which tron 
remains passive in solutions of various oxidizing agents. A series of 
measurements of “single potentials” carried out under simplifying 
conditions. 
15. Dr. W. S. Lemon: The toxicity of solutions containing phenol 
and sodium chloride. The work of Professors J. J. Mackenzie and W. 
Lash Miller has been continued. The toxicity of a solution of phenol 
and salt is slightly greater than that of a pure phenol solution in equili- 
brium with the same solution of phenol in toluene. 
16. R. B. Stewart: The reaction between 1odine and starch. 
Colorimetric measurements shew that the reaction is slow enough for 
kinetic measurement; the rates of the two reactions and the equili- 
brium between them are being studied as a contribution to our know- 
ledge of the mechanism of reactions in colloidal solutions.
