INDIUM. 183 



ditional experiment, tlie third as given below, was made after the method 

 of Reich and Ixicliter. The third column gives the percentage of In in 

 In A: 



1. 124 i^rin. In gave I.3616 gnu. 10203. Per cent., 82.550 



I. 015 " 1.2291 " " 82 581 



.6376 " .7725 " " 82.537 



These figures were confirmed by a single experiment of Bunsen's * 

 published simultaneously with the specific heat determinations which 

 showed that the oxide of indium was In,,03, and not InO, as had been 

 previousl}^ supposed : 



1.0592 grm. In gave 1.2825 grm. In.,03. Per cent. In, 82. 589 



For convenience we may add this figure in with AVinkler's series, which 

 gives us a mean percentage of In in In.,03 of 82.564, ±: .0082. Hence, if 

 O = 15.879, ± .0003, In = 112.787, ± .0542. 



Combining both values, we have — 



From gold series In ^ 1 13. 179, ± .05 1 7 



, From oxide series. ... " = 112.787, ± .0542 



General mean In = 1 1 2.992, ± .0374 



IfO-= 16, In = 113.853.
