lil the tables J — 3 tlie results have heen recorded of three sets 

 of observations. In tlie first and second cobinins of everv table the 

 teniperatiires and the corresponding three-phase pressures (in cm.) 

 are given, the last have been reduced to inercnrv of 0° 0. The third 

 cohinin contains the tensions corrected for the vapour tension of ice, 

 the fourth and the fifth contain the differences in the Bkigg loga- 

 rithms of the pressure and in the reciprocal absolute temperatures 

 of the successive observations. The sixth column gives the value of

made with Neperian, in tables I — 3 with ordinary logarithms, the 

 modulus 2.30H occurs here in llie denominator. The last column 

 records the mean values of the last mentioned expression. The first 

 value of /'' in table 3 is too high; it probably refers to the equili- 

 brium hydrate-gas (cf. § 7). It is easy to see that the too small
