92. CONDUCTANCE-CAPACITY OF THE BOMB. 



The conductance-capacity of the bomb at 18 (i. e. the factor by which 

 the observed conductance must be multiplied to give the specific conduct- 

 ance) was determined with known solutions of sodium and potassium 

 chlorides. The values adopted for the equivalent conductances of these 

 salts are those given by Kohlrausch.* 



Table 93 gives the actual conductances in the bomb of the various solu- 

 tions, diminished by the conductance of the water, as determined from a 

 measurement made just before mixing. Separate fresh solutions were 

 used in each case. The conductances are given in reciprocal ohms, the 

 concentrations in milli-equivalents per liter of solution. 



*Mean of two almost completely concordant experiments. 



The results dated August, 1905, are those of Mr. Kato. The first of 

 his final values was used in connection with his conductance data obtained 

 up to August 26 inclusive. The second mean value was used with all 

 his later data those obtained from August 31 to September 16. 



In computing the conductance from our measurements made prior to 

 March 20, 1906, the value (1.2181) for the conductance-capacity obtained
