with the temperature, and that the amount of bismuth dissolved by 

 zinc, or vice versa, regularly increases as the amount of tin present 

 increases, just as in the case of the corresponding alloys containing lead 

 instead of bismuth. Figs. 2 and 3 represent the solubility curves, the

curves marked 1 and 2 respectively indicating the values obtained at 

 650 and 750 ; the dotted lines connect the actual points of observa- 

 tion, whilst the continuous lines represent the smoothed mean curves 

 thence deduced. The following solubility tables are derived from 

 these mean curves.
