Milk and Its Products 



By henry H. wing 



Professor of Dairy Husbandry in Cornell University 



N^eiv Revised Edition, with new illustrations, cloth, i3mo, $1.^0 



The revolution in dairy practice, brought about by the introduc- 

 tion of the centrifugal cream separator and the Babcock test for 

 fat, by a more definite knowledge regarding the various fermen- 

 tations that so greatly influence milk, and the manufacture of its 

 products, have demanded the publication of a book that shall 

 give to the dairyman, and particularly to the dairy student, in 

 simple, concise form, the principles underlying modern dairy 

 practice. Such has been Professor Wing's purpose in this 

 work. This is not a new edition of the author's very successful 

 volume published under the same title many years ago ; it is, in 

 reality, an entirely new book, having been wholly reset and en- 

 larged by the addition of new matter, both text and illustra- 

 tions. The author's aim has been at all times to give the pres- 

 ent state of knowledge as supported by the weight of evidence 

 and the opinions of those whose authority is highest.
