apparent, while the order in which these are rantjed possesses certain 

 points of interest that may be noted here. 



Table I. The Delermination of the Partial UlerUisation Point 

 by the Titration Method. 



(The results are expressed as c.c. N/10 acid required to 

 neutralise the whole of the filtrate.)

Curve 1. Tlic Dctcriniiiation of the .Amount of Caustic Lime required to induce 

 Partial Sterilis.ition of a Soil. 



The addition to any soil of the amount of lime indicated by this 

 titration method is sufficient to affect appreciably the reaction of 

 the soil water and lieuce may be expected to displace more or less
