Table for the Determination of Maltose.=—The copper and alkaline solutions employed for the oxidation of maltose are the same as those used for invert and milk sugars. In the manipulation twenty-five cubic centimeters each of the copper and alkali solutions are mixed and boiled and an equal volume of the maltose solution added, which should not contain more than one per cent of the sugar. The boiling is continued for four minutes, an equal volume of cold recently boiled water added, the cuprous oxid separated by filtration and the metallic copper obtained in the manner already described. The weight of maltose oxidized is then ascertained from the table. _Example._ Weight of impure maltose taken, ten grams to a liter: Quantity used, twenty-five cubic centimeters: Weight of copper obtained 268 milligrams: Weight of maltose oxidized 237 milligrams: Weight of impure maltose taken 250 milligrams: Percentage of maltose in sample 94.8.
