To show how closely these compounds yield the con- 

 stant "c," where c --- M 2 K/(Mol. Wt. X Valences) 273 , Table 

 II is appended. "C" was found in a previous paper to be 

 about 2.98 X io~ 37 for other than chlorine compounds. 

 Chlorine is throughout considered as trivalent.

 SIDERED TRIVALENT EXCEPT IN HYDROCHLORIC ACID AND 

 PROPYL CHLORIDE 



Mean (omitting HC1, S 2 C1 2 and CC1 3 CHO), 2.99 



The answer to the question whether chlorine is trivalent 

 or monovalent is given in no indecisive manner by the method
