On the Composition of Linseed Oil- Cake, 



The nitrogen is, on the aveage of these specimens, somewhat 

 lower than in the case of the French and American series ; but 

 this arises from the extreme lowness of specimens Nos. 16 and 22. 

 If these be thrown out, the average on the remaining seven 

 samples will be 4'66, which practically does not differ from the 

 mean of the French and American. Of the other varieties I 

 have fewer samples to describe. 



The following are analyses of two specimens of Russian
