tThe mean of all the anode values is 168.3 but it seems best to omit the first four, in which 

 experiments an anode of small surface was used, and which are somewhat lower perhaps owing 

 to the evolution of a small quantity of chlorine. 



116. SUMMARY AND DISCUSSION. 



The final results of the transference experiments described in this article, 

 as well as of those carried out by Noyes and Sammet* with 0.05 0.006 

 normal hydrochloric acid at 20, f are brought together in table 138. 

 In this table are also given the values of the equivalent conductance of 



*Ztschr. phys. Chem., 43, 63 (1903) ; J. Am. Chem. Soc, 24, 958; 25, 167 (1902-3). 



tCorrected for the inaccuracy in their calculation as described in a preceding foot- 

 note.
