        Following a review of the literature, experiments are described that deal with the reactions of CO and of CO₂ and C₂H₂ in the presence of catalysts, the object of which is to aid in explaining the origin of higher hydrocarbons in the reduction of CO and of CO₂ by H₂.  The gaseous mixture was passed over the catalyst at constant temperature and the compositions of the entering and issuing gases were compared.
