General Mean of Residts. 
If each of the foregoing series of experiments be represented by the result calculated 
from the aggregates of material used, and if equal weight be attached to the results of 
all the methods, the general mean derived from the whole of the 34 expeiiments will 
be as follows :— 
First series. 
196-722 
Lowest value. 
Second series. 
196-790 
Third series. 
196-775
