PLEURO-PNEUMONIA IN THE UNITED STATES. 
Editor American Veterinary Review. 
Dear Sir: —In the editorial of your February issue, you 
draw attention to the fact that several times within the past

monia, and were so for at least twelve years prior to that time, 
having the identical specific lesions, symptoms and history 
special to and typical of this disease. I had no difficulty then 
in recognizing and diagnosing my old friend, with whom I had

I, with many others, was very skeptical as to its ultimate success 
as a means of eradicating this disease, for the following reasons: 
I it had been allowed full sway among all classes of cattle
