These mixtures (Tables , fig. 3) show againthe phenomena of minimum critical temperature and maxi-mum vapour-pressure which had been found with mixtures of Fig. 3. {Vide Tables I., IV., ). Temperature 0. ethane with N20 and C2H2. The minimum critical tempe-rature occurs for a mixture tr = 045 about (A), the maximumvapour-pressure for .i-^OSO approximately (B). These com-positions are nearer together than for N20-C2H6, but not sonear as for C2H2-C2HG. Phenomena of some Substances and Mixtures. 189 25. Again, the critical phenomena characteristic of mix-tures were very little marked. As just stated, mixtures con-taining ethane between the limits 030 and 0*45 ought theo-retically to show the critical phenomena of the second mixture 0*43 points P and C were, however, so neartogether that I could not observe a difference. For mixture0-50 P is between M and C ; for mixture 0*30 M and Pcoincide, and very nearly also with C ; for mixture 0*15 Mseems to lie between P and C. All this agrees with the rulesgiven above. The differences between pb and pe are verysmall, especially for the maximum
