   I don't know Kaye and Laby.  "Experiemtnal Techniques in Low Temp. Physics" by   
   Guy White, has a few nice tables.. but not worth the price of the book..give   
   nthe web these days.   
      
   Unfortunately the volumetric heat capacity is basically constant.   
   (numbers taken from various places and subject to the normal errors on the   
   web.)   
      
   Material     Heat capacity (J/(K*cm^3)) at 300K.   
      
   Aluminum      2.42   
   Copper        3.4   
   Iron          3.5   
   Al2O3         3.0   
   G-10          2.7   
   Nylon         1.7   
      
   I guess the molar density of everything is basically constant.   
   All atoms are the same size.  I wonder if there is some fundamental reason for   
   this.
