From these Tables it is evident that there is in general a 

 satisfactory, and in part a strikingly good accordance between 

 the values of p calculated from the formula and those observed; 

 nevertheless, at the greatest densities of carbonic acid reached 

 in the experiments, amounting to four or five hundred times 

 the densities occurring under the pressure of one atmosphere, 

 considerable differences are met with. These at first induced 

 me to undertake another modification of the formula, by intro- 

 ducing into the second term a temperature-function as a factor 

 in order to balance the differences. Through this, however, 

 the formula lost its simplicity ; and the question arose whether
