SOLID ELEMENTS, AND THEIR PERIODIC RELATIONS. 



65 



The compressibilities, atomic weights, and atomic volumes of a majority 

 of the commonly solid and liquid elements. 



[Compressibility of mercury = 0.00000371.] 



1 Standard. 



In tracing the relationship between the data recorded in this table, the 

 first fact which impresses the observer is that compressibility is a property 

 as definitely periodic as any other property of the elements. This is 

 clearly demonstrated by the diagram appended, which shows the relation 

 between the atomic weight and the compressibility of the elements, plotted 

 in the same manner as the well-known atomic volume curve of Lothar 

 Meyer (fig. 8).
