"This table contains only a moderate number of the many determinations which have been made 

 relative to the specific gravity of alloys. Only those alloys have been admitted which allow of rela- 

 tively simple chemical form u lea. Some of them are doubtless true chemical compounds, but in, 

 most cases the formuhe merely represent proportionate composition.
