If Fp is constant, then P^ should be proportional to the volume 

 of gas sent in. 



Tabulating this way, we get: 



In some cases the agreement is better than in others. 



Henry's law tells us that the volume of gas dissolved by a given 

 volume of liquid is independent of the pressure. In this statement, 

 the volume of gas is supposed to be measured at the existent pressure. 

 The mass of gas dissolved is proportional to the pressure. In my 

 experiments the volume of the liquid increased linearly with the 

 volume of gas passed in. Working on this basis it should be possible 

 to find the equation of the pressure curve. 



Let n = number of units of volume passed into G. If there is no 

 solution of nitrogen, etc., in the methane, the pressure is proportional 

 ton. Let us say, pressure = k n. 



If solution occurs according to Henry's law, then since the volume 

 of the methane is proportional to n there will be on this account alone
