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 net 
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.
