Comparison of different me- 

 thods for estimating zinc 



The preceding references show that a large number of electrolytic pro- 

 cesses for the estimation of zinc have been pi'oposed during the last twiinty 

 years, many of which are said to yield accurate results. Seven of these 

 methods have been investigated. Since the completion of these experi- 

 ments in 1897, a comparison of the different methods for the estimation 

 of zinc has been published by Wolman (v. ante). This has made further 

 work on the simple estimation of zinc unnecessary ; our comparative con-
