                  In the catalytic reduction of CO contained in water gas by CuO, Co₂O₃, and MnO₂, a test was made at 254°, which was lower than any previous temperature used.  here the contraction was less than at higher temperature, but the yield of liquid and solid hydrocarbons was higher.  The necessity of extreme purification of water gas to maintain activity of a catalyst activated by successive oxidations and reductions is shown.
