120 C. E. Lmebarger — Apparatus for the Rapid 



ends of the tubes, and s^ the specific gravity. The value of 

 the constant was obtained in the following way. The data for 

 7 and s were taken from Kamsaj and Shields (loc. cit.) and 

 Ramsay and Aston's papers, and those for h from my own 

 measurements. These were set in equation (A) and the value 

 of G calculated therefrom. The greatest pains were taken in 

 the purification of the liquids examined, so that they very 

 probably had the same properties as those used by the inves- 

 tigators just named. The data and results of the calculations 

 are given in Table I for the tubes A and B, and in Table II for 

 the tubes B and C.
