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

 bination of — 



One litre chlorine witli jiotassiuni . . 9329 

 One gramme chlorine with potassium . 2943 

 One gramme potassium with chlorine . 2655 

 One equivalent chlorine with potassium 13008 

 The assumed equivalent of chlorine is its atomic weight, 

 that of oxygen being = 1 .

The compound formed in these experiments was a crystal- 

 line, easily fusible solid. On the addition of water, a white 

 insoluble precipitate was formed ; but when a solution of tar-
