Oil of Cabbage Seed. — M. Frani^ois de Salingre, of 

 llalverstadt, manufactures a refined oil with the seeds of 

 the cabbage plant {Brassica campesiris). Those chemists 

 who hav'c examintd this new production, describe it as 

 possessing the following properties ; 



1. It equals in point of yellow colour and purity the 

 finest oil of Provence. 



2. It is inodorous, and has a taste of almonds, which' 

 distinguishes it from the oil of rape-seed. 



3. It may be substituted for olive oil in sallads, and for 

 other domestic uses. 



4. When used as lamp oil, it gives a bright flame with- 

 out smoke. It is also very ceconomical ; a given quantity 

 will be consumed much more slowly than the same quantity 

 of rape oil within the same time.
