BICE 20 BICYCLE in water containing carbonic acid gas, as carbonate of calcium thus dissolved, reprecipitated on boiling. Bicarbonate of potassium, KHCO?, is obtained by passing CO2 gas through a saturated aqueous solution of KjCOa (potassium carbonate). It crystallizes in colorless rhombic non-deliquescent crystals, which are soluble in four times their weight of water. It does not give a precipitate with BaCU in the cold. Bicarbonate of potassium is a direct antacid, and is em- ployed in the treatment of acute rheu- matism and for removing uric acid from the system. BICE, the name of two colors used in painting, one blue, the other green, and both native carbonates of copper, though inferior kinds are also prepared artificially.

In the early, and now obsolete form, the bicycle was propelled by striking the rider's feet on the ground. The rider sat upon a figure or frame, roughly resembling the body of a horse.
