PREFACE IX 



mann's elaborate treatise on The Science and Practice 

 of Dairying (Blackie), translated and edited by 

 Professor Wright and the Author. 



The sources from which the Author has drawn are 

 too numerous to admit of detailed acknowledgment. 

 At the end of the book a short list of some of the 

 books and treatises on the subject are given. He 

 would, however, take this opportunity of specially 

 acknowledging his indebtedness to the works of 

 Fleischmann, Kirchner, Fiirstenberg, Duclaux, 

 Freudenreich, and Grotenfelt, and the numerous 

 valuable Bulletins issued from time to time by the 

 United States Government. Too great praise cannot 

 be paid to the last-named Government for the en- 

 lightened policy which they pursue with regard to 

 the circulation of valuable Bulletins, dealing with 

 various aspects of agricultural science. 



For the illustrations the Author is indebted to the 

 writings of Dr. Fiirstenberg, Professor Kirchner, Pro- 

 fessor P. F. Frankland, Dr. James Bell, F.E.S., and 

 Dr. Freudenreich.
