Progress of Foreign Science. 



rubbing assumed a bright metallic lustre. From such experiments 

 lie infers, the composition of the sulphuret to be, 



Metallic titanium 49.17 



Sulphur 50.83 



100.00 

 And supposing the stage of sulphuration to correspond with that 

 of the oxidation in the titanic acid, he considers this as consistingof 



Metallic titanium 66.05 



Oxygen 33.95 



100.00 

 Mr. Rose details some experiments instituted with the view of 

 confirming his opinion about the relative states of sulphuration and 

 oxidation ; but they do not seem conclusive. He considers the 

 atom of titanium to weigh 7.782 referred to oxygen as unity.

 simultaneous Application of Heat aiid Compression to certain Liqirids. 



By the heat of an oil bath, some results have been obtained 

 which seem to indicate such as would be procured by the employ- 

 ment of much higher temperatures. They are presented in the 

 following Tables.
