" The following, therefore, are the means deducible from 



each separate series of observations : 



Series 1 ... m = -01151 



Series 2 -01150 



Series 3 -01140 



1 



So that the mean of all three is -01147 = 



or al- 



87-18' 



most exactly the coefficient which I have given in my 

 papers on the dew-point." 



Mr. Lloyd then proceeded to offer some remarks upon 

 Dr. Apjohn's communication, and upon the most probable 

 value of the coefficient to be derived from his results.
