Briefly stated the results of the investigation are : 



1. Tfee (quantity of nitrogenous material is inversely proijortioned to the 

 •<iuautity 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- 

 pear 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 Robert E. Lyons. 



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

 'tellurium was observed by Frederick Woehler and other chemists of his time. 



To trace this 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 prepared after the Friedel-Crafts' reaction, but this method in my 

 hands did not lead to satisfactory results. 



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

 i. e., the replacement of the SO2 group in the sulfone by sulphur or selenium : 

 C,U,. SO,. C^Hs + S = C^H^. S. C,H, -f SO^. 

 Diphenylsulfone. Diphenylsulfid. 



■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 (CgHj),, the diphenyltelhiride would be ob- 

 tained according to the following reaction: 



C,K,. Hg. C,H5 +Te Cl^ -C^H^. Te. C,U, + HgCl^.
