could be expected for measurements for this nature. The means 

 shown in the curves are: O.O3IO4, O.O3II8, O.OslSS, and O.OaSl. Com- 

 parisou may also be made with the values of Amagat,^^ which are 



TABLE IV. 



Cb for Ethyl Alcohol. 



O.O498I at 14° and O.O3I96 at 99.4° at a mean pressure of 22 atmos. 

 The agreement at the lower temperature is good; the upper tempera- 

 ture is beyond the range. 



For Cp at atmospheric pressure we have a number of values which 

 are shown in Table IV. The results are in very bad agreement, as 

 may be seen by plotting them. It is however, perfectly certain that 

 on the whole Cp for ethyl alcohol increases with rising temperature.
