PREFACE 



This book is intended for those students of Agri- 

 cultural Chemistry who desire a knowledge of com- 

 mercial quantitative analysis. 



The first two chapters deal with ordinary quanti- 

 tative analysis, and may be omitted by those who 

 have already received a general training in practical 

 chemistry. The remainder of the book contains an 

 account of those processes which the experience of 

 many workers has shown to be the most useful to 

 the agricultural analyst. 



In this second edition the original arrangement 

 of the book has been retained, but the chapters on 

 the analysis of dairy produce and of water have been 

 re-written. 



It would be well-nigh impossible, in a volume of 

 this size, to acknowledge all the sources to which I 

 am indebted for assistance, but the mass of the in- 

 formation here given was acquired whilst working in 

 the laboratory of the Royal Agricultural Society of
