i. R. A. Daly: Analysis of the reactions leading to the formation 
of phthalonic acid from naphthalene by alkaline solutions of perman- 
ganate. By studying the rates of oxidation, it was shewn that severai 
probable intermediate products cannot be formed as such; and the basis 
was laid for a new method of elucidating the mechanisms of organic 
reactions. The paper has been published in the Jour. Phys. Chem., 
vol. 11, pp. 93-106. 
8. M. C. Boswell: The mechanism of the oxidation of naphthalene 
by chromic acid. In this paper it is shewn how by a few simple 
measurements valuable information on the course of an organic reaction 
may be acquired; the method is applied to the study of the genetic 
relations of a number of the oxidation products of naphthalene. The 
paper has been published in the Jour. Phys. Chem., vol. 11, pp. 
119-131. 
9. M. C. Boswell: The detection and estimation of the naphtho- 
quinones, phthalonic, and phthalic acids. Volumetric and gasometric 
methods are described for determining these substances alone or in mix- 
tures. The paper has been published in the Jour. Am. Chem. Soc., vol. 
29, pp. 230-236. 
10. C. F. Marshall: The oxidation of ethyl alcohol by chromic 
acid. An analytical method was worked out, and measurements under- 
taken, to see whether acetaldehyde is invariably the first step in the 
oxidation. Under the conditions of the experiments it was found 
to be so. 
11. ZX. B. Stewart: The action of iodine on sodium thiosulphate 
in alkaline solution. The impossibility of obtaining constant results 
when titrating thiosulphate with iodine in alkaline solution was found 
to be due to the gradual hydrolysis of the tetrathionate formed, and to 
the action of the iodine on the products of hydrolysis. A study of the 
hydrolysis itself shewed that under certain circumstances dithionate 
may be formed. 
12. L. F. Lewis: The transport numbers of sodium and potassium 
chlorides in solutions containing acetone and water. Acetone, unlike 
alcohol, glycerine, and the other substances heretofore experimented 
with, strongly affects the transport numbers of these salts in aqueous 
solution. This fact must be reckoned with in interpreting fhe results 
of conductivity measurements in aqueous acetone. This paper will 
shortly appear in the Jour. Phys. Chem. 
13. S. Dushman: The behaviour of copper as anode in solutions 
of chlorides. Increasing the concentration of the chloride, or rotating 
the anode, increases the yield of cuprous salt. The experiments so far 
made are in accordance with the supposition that the solution formed at
