The specific heats of nitrogen, oxygen, and fluorine have 

 not been determined in the solid state, while the values 

 obtained from the specific heats of their compounds are well 

 known to be abnormally low, as are those of beryllium, boron, 

 carbon, and silicon, which have been determined directly with 

 the elements in the solid state. Even in the case of the latter 



elements, the values calculated from the expression 



are not very far from the experimental numbers, while in all 

 others, except those of calcium, gallium, and germanium, the 

 agreement is remarkably close. The experimental value for 

 calciumis apparently too high, being greater than that ofpotas-
