One of the familiar mixtures is the so-called malt soup, the use of which was modified by Keller of the University Clinic for Children at Breslau to include potassium carbonate. Various claims have been made for seemingly empiric combinations. The assimilability of the malt sugar has been highly lauded, though the evidence for this alleged superiority over other available carbohydrates is by no means overwhelming, however probable it may seem on theoretical grounds.
