was expressed in the laboratories of the Bureau of Chemistry from 

 a good grade of cleaned mustard seed imported by that bureau.

 mercial conditions, it was assumed to be quite similar to the com- 

 mercial mustard-seed oil. 



The results of the tests made with unrefined oil are summarized 

 in the following tables :
