METHOD OF DETERMINATION MOLECUI;AR WEIGH7'S. 4 [ 



With regard to the molecular weight of sulphur in carbon 

 bisulphide solution Reckmann, by the boiling method, oljtained 

 numbers varying between 245 and 281 and, therefore, pointing to the 

 existence of complex sulphur molecules represented by 8^=256. The 

 formula Sg had generally been regarded as the mnximum molecular 

 formula of sulphur, and the results obtained by Ijeckmann, therefore, 

 needed confirmation. The experiments by Hertz (loc. cit.) who obtained 

 numbers varying between 262.3 and 279.4 and, still more conclusively, 

 my own determinations, put Beckmann's views beyond any doubt.
