Transpiration of Imprisoned Air into Hydrogen Through Water.— The immediate use of equation (i) is inadmissible, since the gas constant Rvaries, as the gas within the swimmer changes its composition. But sinceat a given pressure and temperature Rp is constant for all mixtures, m = vp = Mgp, R T P, o P/ is still the correct value, relatively to volume, as intimated above. It ismerely necessary, therefore, to coordinate the correct value of p for theinitial gas and its gas constant R, after which the equation is applicable toall subsequent gas mixtures, if the diffusion k by volume is to be computed;but m is now merely an apparent rate, and k merely a transitional value. 26 THE DIFFUSION OF GASES THROUGH The experiment of this section is the converse of those briefly detailed ia table 2 and repea
