Although the results obtained in this work have not fulfilled our expec- 

 tations as regards adding to previous ideas on the nature of group ionisation, 

 our knowledge of phosphorus ionisation has been considerably extended. 

 We hope that the further experiments, which will enable a high degree of 

 drying to be reached, may throw light on the nature of these numerous 

 groups of ions.
