Fig. 3 contains the points corresponding to the observa- 

 tions recorded in all the tables. The number attached to 

 each point indicates the table which supplied it. 



I repeated a few of the observations with hydrogen and 

 oxygen prepared by the electrolysis of a solution of caustic 

 potash, to decide whether the gases generated in this way, 

 associated as they are with various impurities, would yet 

 follow the same laws of partial union. The results are given 

 in Table VIII. They show no perceptible departure from
