Section V. contains a list of apparatus and chemicals 

 lequired for performing the experiments described in this 

 book, together with instructions for preparing the various 

 solutions. 



After working through this course, students are recom- 

 mended to consult Addyman's ' Agricultural Analysis.' 



Our acknowledgments are due to Professor F. Clowes, 

 D.Sc. (Lond.), for permission to use woodcuts and other 

 material from his text-book on Qualitative Analysis. 



In the preparation of the present edition, the whole of 

 the existing matter has been carefully revised. Some por- 

 tions have been re-written and important additions have 

 been made.
