532 Mr. Raukine on the Centrifugal Theory of Elasticity, 



The table shows only one instance in which the difference be- 

 tween the result of the theory and that of experiment exceeds 

 •0000136; the limit, according to M. Regnault, of the errors of 

 observation capable of arising from one cause alone, — the uncer- 

 tainty of barometric measurements. That discrepancy takes 

 place in one of the determinations of the coefficient E' for car- 

 bonic acid gas under the pressure of one atmosphere. In the 

 other determination, the discrepancy is less than the limit. 



The agi'eement between theory and experiment is most close 

 for the highest pressures ; and M. Regnault has shown (p. 100) 

 that the higher the pressure the less is the effect of a given eiTor 

 of observation in producing an error in the value of the co- 

 efficient. 



The theory is therefore successful in calculating the coefficients 

 of dilatation of gases, so far as the means at present exist of put- 

 ting it to the test.
