244, REPORT—1896. 
The Electrolytic Methods of Quantitative Analysis.— Third Report of the 
Committee, consisting of Professor J. EMERSON REYNOLDS (Chair- 
man), Dr. C. A. Koun (Secretary), Professor P. FRaNKLAND, Pro- 
fessor F. Clowes, Dr. HucaH Marsnaui, Mr. A. E. FLETCHER, 
Mr. D. H. NaGeu, and Professor W. CarLeToN WILLIAMS. 
Tue bibliography of the subject having been completed for the last Report, 
the Committee have been able to give their full time to experimental work 
during the past year. In addition to the appended results on the arrange- 
ments adopted for the work, the determination of bismuth, antimony and 
tin, and the separation of the two latter, the work on the determination of 
cobalt, nickel and zinc is well advanced, and will be included, together with 
further work on bismuth, in the next Report of the Committee.

The examination of methods for the electrolytic estimation of this 
metal was conducted in the chemical laboratory of Trinity College, Dublin. 
‘The electrolytic department of the laboratory is fitted in the usual 
way. The currents required are derived from the ‘ Bristol’ type of storage 
cells, made up in sets of six in each case, with connections so arranged. 
that currents of 2 amperes and 4, 8, or 12 volts can be obtained as required. 
These cells, which are compact and light, have given very satisfactory 
results during two years’ frequent use, and are now in perfectly good order.
