compared with those of the polymeric form of carbon monosulphide 

 obtained from the interaction of thiophosgene and nickel carbonyl, 

 and the results indicate that the difference between the broWn sub- 

 stance obtained by the action of the electric discharge on carbon 

 disulphide vapour and the polymeric form of carbon monosulphide 

 obtained from thiophosgene is merely in the degree of polymerization. 

 The Fulleriau Professorship of Chemistry was endowed by John 

 Fuller in 183fi as a recognition of the great work of Faraday. He 

 held the office for thirty-four years, and if the lecturer is spared for a 

 few months he will be able to look back on the same long period of 

 service. Some member of the younger generation of chemists or 

 physicists will soon have to continue the work of research at the 

 Royal Institution.
