The Number of H Equivalents 



The value of V/W, which is the volume of H, first 

 diminishes to H . COOC 4 H 9 W = 35, and then increases in a 

 straight line from that point quite abruptly. 



Most of the curves possess features similar to the foregoing, 

 but are somewhat different in form. 



An interesting curve is that of the normal Paraffins, 

 which unfortunately extends only to C 8 H 20 .
