(1) A carbohydrate easily fermented by yeast, free from glucose and glycogen, was isolated as a slightly impure, amorphous powder in 0·07 per cent. yield from rabbit liver. The solubilities and general properties of the carbohydrate were those of a mixture of dextrins containing free, copper‐reducing groups. It gave no colour with iodine. (2) The amorphous acetate of the above had a specific rotation of 127° in chloroform and a nitrogen content of 0·28 per cent. It contained no detectable amount of sulphur or phosphorus. A Carnegie Teaching Fellowship enabled the author to carry out the work.
