LETTER OF TRANSMITTAL. 



U. S. Department of Agriculture, 



Bureau of Animal Industry, 

 Washington, D. O. , September 31, 1908. 

 Sir: I have the honor to transmit herewith the manuscript of a 

 revised edition of the Special Report on Diseases of Cattle, in accord- 

 ance with the following resolution, approved May 23, 1908: 



Resolved by the Senate and House of Representatives of the United States of America in 

 Congress assembled, That there be printed and bound one hundred thousand copies 

 of the Special Keport on the Diseases of Cattle, the same to be first revised and 

 brought to date under the supervision of the Secretary of Agriculture; thirty thou- 

 sand copies for the use of the Senate, sixty thousand copies for the use of the House 

 of ^Representatives, and ten thousand copies for distribution by the Department of 

 Agriculture. 



This work was originally issued in 1892, since which time there has 

 been such a demand for copies that several editions have been printed 

 by order of Congress. It was revised in 1904, and has again been 

 revised in accordance with the resolution above quoted. The changes 

 made in the present edition consist mainly in the revision of the chap- 

 ters on diseases of the digestive organs and infectious diseases and the 

 substitution of a new chapter on animal parasites for the chapter on 

 that subject in the edition of 1904. 



While the work is of a popular character, and is intended primarity 

 for the use of the farmer and the stock owner, it will doubtless also 

 continue to be found useful to the student and the veterinary prac- 

 titioner. 



Very respectfully, A. D. Melvin, 



Chief of Bureau. 

 Hon. James Wilson, 



Secretary of Agriculture.
