PKEFACE TO SECOND EDITION 



FOR some considerable time this little book has been 

 out of print, but the author has now found time to 

 make a few necessary corrections and add informa- 

 tion to bring it up to date. A number of new methods 

 have been added, and an endeavour has been made to 

 give information which will aid in the solution of those 

 practical problems which confront the dairy chemist. 



October 1912 H. D. R. 



PEEFACE TO FIRST EDITION 



THIS work is intended to contain working directions 

 for the analysis of milk and dairy-products ; the esti- 

 mation of all constituents of diagnostic value is shortly 

 described in detail, and is in many cases illustrated 

 by photographs of chemists actually carrying out the 

 determination. 



A chapter on the application of analysis to the solu- 

 tion of problems usually placed before the chemist is 

 included, and a very short summary of the composition 

 of milk and its products is given.
