OF SILVER BETWEEN ZINC AND LEAD. 



These results leave much to be desired. But the accurate 

 determination of small quantities of silver contained in large 

 amounts of the heavier layer is particularly difficult, and a 

 tolerably wide range of error must be allowed even on this head 

 alone. In the table the results are arranged in the order of the 

 increasing percentage of silver in the lighter layer, and the 

 partition coefficient does not show any tendency to rise or fall 

 with the same. Hence we must conclude that it is actually 

 constant at least for the more dilute solutions of silver in zinc 

 and lead. This proves beyond doubt that whatever compounds 

 of silver and zinc may occur in the lighter phase, other than 

 those corresponding to the molecular formula Ag Zn^ must be 

 in such minute quantities that they do not influence the partition 

 coefficient materially.
