Prof. Tait in the introduction to this paper. The results of the application of 

 these corrections are given in the following table along with the results given 

 already. The numbers in brackets indicate the conductivity as deduced from 

 data uncorrected for the error in question, those without brackets indicate that 

 from corrected data. 



It will be observed from a comparison of the corresponding numbers, that 

 the effect of applying this correction is to make the conductivity more nearly 

 constant at different temperatures.
