              with the exhaust gases produced by an internal combustion engine comprising:                             
                     providing a refractory inorganic oxide deposited on a monolithic substrate;                       
                     contacting the refractory inorganic oxide with a tungsten containing compound                     
              and calcining to make a tungsten oxide treated material;                                                 
                     contacting the tungsten oxide treated material with a basic metal precursor and                   
              calcining to make a basic metal oxide treated material, wherein the basic metal oxide                    
              has a pH  greater than tungsten oxide and the refractory inorganic oxide contains no

              more than 35 weight percent of the total weight of the basic metal oxide; and                            
                     contacting the basic metal oxide treated material with a noble metal containing                   
              compound and calcining.                                                                                  

                     The reference relied upon by the examiner in the rejections before us is set forth                
              below:
