III. A CONSIDEEATION OF SOME POSSIBLE REASONS FOR THE 

 DIFFERENT LiME REQUIREMENTS OF THESE SoiLS. 



1. Calcium oxide. In trying to discover the reason for the different 

 acidities displayed by these soils the customary appeal to chemical 

 analysis was first made — more especially to determinations of lime — 

 with results that are shown in Table X.
