The heat due to the solution of the compound, referred to 

 one litre of chlorine as unit, was found to be 260 units. 



We have, therefore, for the heat evolved during the com- 

 bination of — 



One litre chlorine with copper . . 



One gramme chlorine with copper . 



One gramme copper with chlorine . 



One equivalent chlorine with copper 



The results of the foregoing experiments are contained in 



the following table. I have adopted the number 7900, for 



the reasons given in the note, to express the heat produced 



during the combustion of carbon; and have also added, from 



a former publication, the numbers which correspond to the 



heat evolved during the combination of chlorine and iron. 



Combinations of Oxygen. 

 Of oxygen.
