[Footnote 1: Brewer's scale.]

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-and-rice and

malt-and-corn beers; that is, the beers have a lower protein and

phosphoric acid content than those made entirely from malt.
