The vapor pressures are now larger,t = 7r( 1 — ) being the value inserted and holding as above stated for reduction to KC1 requires ir = 71-(1 —), so that the correction57r = and in —(dv0/dH)8ir= —(v0/H)8irt the factor 57r7# = too small to make its effect appreciable. In other respects the experi-ments were made as above. Table 25 and fig. 23 show the Fig. 23.—Chart showing loss ofstandard volumes of gas in diverin lapse of days.
