BULLETIN 687, U. S. DEPARTMENT OF AGRICULTURE. 
was expressed in the laboratories of the Bureau of Chemistry from 
a good grade of cleaned mustard seed imported by that bureau. 
While it was expressed under laboratory rather than under com- 
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 :
