Milk and Its Products 



By HENRY H. WING, Professor of Dairy Husbandry in Cornell 

 University. 



New Revised Edition, with new illustrations. 

 Cloth, 12mo, $1.50 



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

 duction of the centrifugal cream separator and the Babcock test for 

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

 tions 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 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.
