The run of the thermometer on the same sheet, fig. 6, bears out this surmise. The barometer, like the vapor pressures, shows no easily discernible relation to the weight curve; but the run of temperature fore- shadows the kinks in the m curve throughout its 3^e(>. 5 iO 15 20 Z^JiatZ 7 1Z m Zl Z7 Jlpvi 6 11 Fig. 6.—Loss of mass of gas in diver in lapse of days. Diffusion of air into air. If we write for the air-water system (time t in days, mass m in grams) m = Wq — mt and compute the constants pIq and in by the method of least squares from the 68 observations made between January 31 and April 11, the values obtained are Wo = gram w = gram/day.
