Individual 
determination. 
Departure of individual 
determinations from 
average of io previous 
determinations. 
a The data in italics would in practice be rejected, but serve to illustrate the importance of duplicate 
determinations. 
Another illustration is afforded by the data in Table XI on distinct 
sets of samples taken from the same localities as those appearing in the 
preceding table.
