          Appeal No. 95-4491                                                          
          Application No. 07/864,210                                                  


          2 attached to the declaration.  In comparison, Figure 3 is                  
          said to illustrate the osmolality of a chondroitin sulfate                  
          solution at room temperature, and Figure 4 is said to                       
          illustrate the viscosity of a sodium hyaluronate solution at                
          room temperature.                                                           
               The declaration and evidence presented in support thereof              
          are inconclusive for several reasons.  First, the osmolality                
          of the chondroitin sulfate solution at 4EC and the sodium                   
          hyaluronate solution at 4EC and 23EC have not been included.                
          Second, the viscosities of the  sodium hyaluronate solution                 
          appear to have been plotted on logarithmic graph paper.  In                 
          contrast, the viscosities of the chondroitin sulfate/sodium
