This represents a ratio between bismuth and zinc not far from that 

 indicated by the formula BiZn a ; whereas the corresponding ratio with 

 tin as solvent metal was found to be not far from that indicated by 

 BiZn 10 .

The dotted lines I and II at the base of the critical curve represent 

 respectively the values given in Series I (Part III), obtained by 

 fusion for eight hours, and in Series II and III, obtained by separate 

 further fusion of the lighter and heavier alloys thus formed. Like
