Translator's Preface, 



have included much valuable information from the reports of the 

 various Milk Commissions, and other sources. For this reason 

 Chapter X dealing with German laws and regulations has been 

 replaced by Chapter XI which deals solely with the conditions and 

 standards existing in this country. 



We cannot refrain from expressing our sincere thanks to Dr. 

 H. J. Washburn for his most valued suggestions and assistance in 

 proofreading the manuscript ; also to the publisher, Mr. Alexander 

 Eger, for his interest and courtesy during the preparation of this 

 volume.
