The above relationship of the two constants /3 and 7 appeared 

 to me most singular and at the same time most interesting 

 if it proved to be of universal occurrence. In order to test 

 this point to some extent, I prepared solutions of BaCl 2 and 

 Sr(N0 3 ) 2 each of three different strengths — one n = 0*5, an- 

 other nearly saturated, and the third intermediate in strength, 

 and determined their densities at 20° C. The results thus 

 obtained are given in Table YI. along with the values of @ 

 and 7 for BaCl 2 , LiCl, and CaCl 2 calculated from the data 

 given by Gerlach*.
