V.— Researches in Physical Chemistry, carried out in the University 
of Toronto during the Past Year. 
By Prorrssor W. Lash MILLER. 
(Read May 27, 1902.) 
The eight papers whose titles follow have already appeared in 
the chemical journals or will shortly be published. Owing to the 
delay attending the publication of the Proceedings, it has not been 
thought advisable to ask the Society to print these papers in full. 
(1) The Application of Polarimetry to the Estimation of Tartaric 
Acid in Commercial Products: — Professor Edgar B. Kenrick (Uni- 
versity of Manitoba) and Dr. Frank B. Kenrick. The influence exerted 
by a large number of substances on the rotation of tartaric acid was 
studied, and methods were worked out for the analysis of the chief 
commercial products containing it. (Jour. Am. Chem. Soc. XXIV. 
928.) 
(2) The Sulphates of Bismuth: — Dr. F. B. Allan. An application 
of the phase rule. The following salts were identified :— Bi,O,.480,, 
Bi,0,.280,.21H,0, Bi,0,.80,. (Am. Chem. Jour., XXVIT, 284.) 
(3) The Rate of Oxidation of Ferrous Salts by Chromic Acid: — 
Miss C. C. Benson. The rate was determined as a function of the 
concentrations of the chromate, the acid, and the ferrous salt. Mea- 
surements of the rate of oxidation of ferrous salts, and of the rate 
at which iodine is liberated, in solutions containing chromic acid 
ferrous salts and iodides, are in progress. 
(4) The Reaction between Slannous Chloride and Water:— Mr. C. 
M. Carson. The results are in conflict with those of Ditte. 
(5) The Rate of Oxidation of Ferrous Salts by Oxygen:— Mr. J. 
W. McBain. Experiments carried out under the direction of Dr. F. 
B. Kenrick. The rates of oxidation of the sulphate, chloride, and 
acetate, were measured with various concentrations of the iron, the 
acid, and the oxygen. (Jour. Phys. Chem., V. 623.)
