BULLETIN 493, U. S. DEPAETMENT OF AGRICULTURE. 
In Tables X and XI are given the results for beers made from malt 
and rice and from malt and corn. A study of these tables shows 
the same condition as was noted in the other tables giving malt- 
aad-rice and malt-and-corn beers; that is, the beers have a lower pro- 
tein and phosphoric acid content than those made entirely from malt.
