From the vacuum distillate 114°-115°, 50 mm., after the seventh 

 distillation, a sulphur oil was prepared by two precipitations with mercuric 

 chloride, that collected after fractioning some time in vacuo for the most 

 part at 114° -11 6°, 50 mm. Under a tension of 750 mm., it distilled at 

 207°-209°, and gave as its specific gravity at 20°, 0.9074. The results 

 of analysis correspond to the formula C 10 H 20 S.

The vacuum distillate 135°-145°, 50 mm., was selected for the sepa- 

 ration of the next homologous sulphur compound. A thick tarry mass 

 was formed by precipitation with mercuric chloride, which gave the pure 

 sulphur oil by a second precipitation. The viscosity of the compounds 

 with mercuric chloride was found to increase with increase in molecular 

 weights of the sulphur oils. 300 grams of the first distillate 135° -145°, 

 fourth distillation, gave, after the second precipitation with mercuric 

 chloride, 122 grams insoluble in alcohol, 60 grams in the alcoholic
