In 1774 he went to Paris, and presented there successively CHRISTOPH WILLIBALD GLUCK several masterpieces, as "Iphigenia in Aulis," "Orpheus," "Armidas," "Iphi- genia in Taurus," "Alcestes."

GLUCOSE, a fermentable sugar, Cs HuOo, which occurs in two modifications, called dextro-glucose, or dextrose, and loevo-glucose (also called Levulose), ac- cording as it turns the plane of polariza- tion to the right or left. A solution of cane-sugar warmed with dilute acids, or left in contact with yeast, is converted into dextrose and levulose, Ci2H220i] + H,0=CoH,20»+C6H,20,:. These modifica- tions can be separated, thus — 10 parts of the mixture of sugar are dissolved in 100
