        Similar experiment was carried out with a catalyst containing Fe, Cu, Mn, and infusorial earth in the ratio 100:25:2:125, respectively, which was reported by Tsuneoka and others (abs. 1885) to be a good catalyst in gasoline synthesis.  Results similar to the case of pure Fe were obtained, except that the t/x-t curve was irregular at 25° and 60°, and above 100° it was a broken line, showing that the adsorption of H₂ above 100° conformed to the second order reaction velocity equation.  In comparison with the Fe-infusorial earth catalyst, there was no marked change in the amount of H₂ adsorbed and its change with temperature at higher temperature, but below 100° the amount of H₂ adsorbed increased.  This increase is considered to be caused by Cu.
