Briefly stated the results of the investigation are : 



1. The quantity of nitrogenous material is inversely proportioned to the 

 (juantity of sugar present. 



2. To a certain limit the increase of sugar is accompanied by a decided in- 

 crease in the quantity of fat. 



At ten percent, sugar the most favorable conditions for fat production ap- 

 l)ear to be overstepped. 



3. Matter soluble in alcohol increases constantly with the increasing per 

 cent, of sugar. 



A New Method for the Preparation of Phenyl-Compounds With Sul- 

 phur, Selenium and Tellurium. By Egbert E. Lyons. 



Tiie very great similarity between the compounds of sulphur, selenium and 

 tellurium was observed l)y Frederick Woehler and other chemists of his time. 



To trace tliis similarity further I was led to attempt preparing certain bodies 

 to fill up the gaps between the known compounds of the organic radicals, 

 methyl, ethyl and phenyl, with sulphur, selenium and tellurium. 



C. Chabrie* gives the results of several years' study of aromatic compounds 

 of selenium jjrepared after the Friedel-Crafts' reaction, but this method in my 

 hands did not lead to satisfactory results. 



On the other hand, tlie method proposed by Drs. F. KraflTt and W. Vorster,t 

 i. e., the replacement of the SOg group in the sulfone by sulphur or selenium : 

 C,U,- SO^. C.Hs + S = CeHs. S. CU, + SO2. 

 Diphenylsulfone. Dipiienylsulfid. 



was easily carried out and afforded 60-70 per cent, of the theoretical amount. 



As excellent as this method is for the preparation of sulphur and selenium 

 compounds, it was nevertheless found, that the sulfohenzid, even after prolonged 

 heating with powdered tellurium, remained unchanged. 



Tellurium dichloride, Te CI2, was next prepared in the hope that through its 

 action upon mercury diphenyl, Hg (C^Hj),, the diphenyltelluride would be ob- 

 tained according to the following reaction : 



CJis. Hg. C.Hs +Te CI^ =C,^U,. Te. CeH, + HgCl^.
