Yet chemistry has been successful in producing from it – sugar, alcohol, etc.; and a German, Professor Karl Schwalbe, has made beechwood digestible with lactic acid, as in the numerous stomachs of some animals. We may look to the day when the householder will “dunk” his morning paper, page by page, as he reads it, and thus use it for toast.
