on page 29 are O.O3IOI, O.O3I24, O.OalST, and O.OsMT respectively. 

 The means adopted for this paper are 108, 124, 140, and 152 respec- 

 tively. There are also ^•alues for the compressibility by other observ- 

 ers, but not under conditions so nearly comparable with those here. 

 These values are: O.O3IO4 at 14.7° and O.O322I at 100° between 8.7

and 37 atmos. by Aniagat^; O.OiOl at 13.5° and 7.5 atmos. by Grassi^; 

 O.O3IO8 at 2.7° and 8 atmos. and 0.0^120 at 18° and 8 atmos. by Ront- 

 gen.^^ The newly published value of Richards for the compressibility 

 at 20° is O.O3IO9 against O.O3IO8 adopted above. 



There are a few measurements for the specific heat, Cp, at atmos- 

 pheric pressure; 20.39 between 5° and 10°, 20.28 between 10° and 15°, 

 and 20.76 between 15°and 20° by Regnault^^ 22.29 between 23° and 

 43° by Kopp;i2 21.56 between 5° and 13° by Lecherj^^ and 21.40 

 between 15.5° and 34.9°, 21.82 between 19.6° and 45°, 22.13 between 

 18.1° and 50.4°, and 22.77 between 20.5° and 63.2° by von Reis.^*
