Milk and Its Products 



By HENRY H. WING, Professor of Dairy Husbandry in 

 Cornell University 



New revised edition. With new illustrations. Cloth, i2mo, $f.fo net 



The revolution in dairy practice, brought about by the introduction of the 

 centrifugal cream separator and the Babcock test for fat, by a more definite 

 knowledge regarding the various fermentations 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 stu- 

 dent, 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, hav- 

 ing been wholly reset and enlarged by the addition of new matter, both text 

 and illustrations. The author's aim has been at all times to give the 

 present state of knowledge as supported by the weight of evidence and the 

 opinions of those whose authority is highest.
