TRANSLATORS' PREFACE. 



Tl;e general excellence of this little work justify the 

 translators in presenting it in this form, with the permis- 

 sion of the author, to the English-reading public. The 

 literature on the subject of milk analysis is by no means 

 limited, but there is a noticeable paucity of manuals or 

 guides adapted to the needs of commercial analysts, mar- 

 ket inspectors and health officers. 



The translators have adhered as closely as possible to 

 the original text. They have taken the liberty to make 

 a few additions in the way of foot-notes. In cases where 

 the methods given do not accord in detail with those 

 commonly practiced in this country at present, refer- 

 ences are made to the standard literature on the subject. 

 A short bibliography has been added in wjiich is cata- 

 logued some of the recent researches along lines within 

 tlie scope of this work.
