On the hypothesis that each atom in a compound behaves as it does in the solid 

 element, the sum of the atomic heats of the elements entering into the compound 

 should he equal to the molecular heat of the compound. The following table contains 

 a comparison of the sum of the atomic heats, A, with the molecular heats, B, of the 

 several compounds, that is, the product of the observed specific heat of the compound 

 multiplied by the molecular weight in each case.
