1. On Certain Products of Decomposition of the Fixed Oils 

 in Contact with Sulphur. By Dr T. Anderson. 



The investigations contained in this paper were undertaken with 

 the view of ascertaining the nature of the action of sulphur in tho 

 free state on organic substances. The author endeavoured, in the 

 first instance, to examine the action of that agent upon some of the 

 simpler organic compounds, but without obtaining any definite re- 

 sults ; and finally confined his experiments entirely to the fixed oils. 



The distillation of oil of almonds with sulphur, which is attended 

 by the violent evolution of sulphuretted hydrogen, afforded a pecu- 

 liar nauseous oil, and a crystalline product deposited on cooling from 

 the latter portions of the oil. In order to ascertain the source of 

 these products, comparative experiments were made with pure stearic 

 and oleic acids. It was thus found, that stearic acid, when distilled 

 with sulphur, gave pi'oducts identical with those obtained by its sim-
