Mean = ‘01140 
“ The following, therefore, are the means deducible from 
each separate series of observations : 
Series1... m= ‘01151 
SORIEH 2): ci cnnctvegos LO 
Series 3.......- “O1140 
So that the mean of all three is ‘01147 = pea » 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.
