Since then several cases have been found which were claimed by the 
English veterinarians to be contagious pleuro-pnuemonia. In the majority of 
cases, sections have been sent to Professor Williams and to Professor Nocard, 
who both, in every case submitted to them, decided they were not contagious, 
but other forms of pneumonia, non-contagious in character. 
Although some of these cases are, to a certain extent, marbled in appear¬ 
ance, they are not, in my opinion, contagious pleuro-pneumonia, for the follow¬ 
ing reasons : First, since my arrival I have not seen a single animal assume the 
characteristic position of contagious pleuro-pneumonia; all that is noticeable is 
dyspnoea and accelerated respiration, moist and not painful cough, with a 
temperature varying from 102 to 104 degrees Fahrenheit. As the animals are 
not used to being handled, auscultation and percussion is out of the question. 
There is very little, if any, protruding of hqad and neck, no aching of the back, 
very little turning out of the elbows, no knuckling of the hind ankles, no 
rigidity or unhealthy appearance of the skin, and no stertorous breathing or 
grunt, as in contagious pleuro-pneumonia. 
Second. The exudation into the pulmonary lobules is of a much lighter 
color, showing the red blood corpuscles are present in large numbers. The 
lymph does not appear so coagulative, gray hepatization is present, fatty 
degeneration and effusion and absorption of serum with a dilatation of the 
lymphatics to a very large extent is also present; pleurisy of the pleura-pul- 
monalis is present over the diseased area; not in a single instance has the 
pleurisy extended to the pleura-costalis. There is no plugging of the bronchial 
tubes and pulmonary arteries; no infarction; in onlyone case was there any 
necrosis, and then only a section about the size of a quarter dollar was so 
affected ; there is no circumscribed area of the affected portion of the lung ; there 
is no effusion into the thoracic cavity as in contagious pleuro-pneumonia. There 
has not been a so-called chronic case of contagious pleuro-pneumonia found since 
we commenced work. 
Third. The diagnosis of the American veterinarians stationed in this 
country has been upheld by such eminent authorities as Professor Nocard of 
France, Williams, Hunter and Bowhill of Edinburgh, Salmon of Washington, 
and J. E. Ryder of New York, also by other disinterested and distinguished 
veterinarians of this country. 
Fourth. Cattle from the same districts in the United States are shipped to 
the ports of London, Liverpool, Glasgow, Hull and Bristol; not a single 
suspicious case has ever been reported from the three latter ports, showing con¬ 
clusively a difference of opinion between the inspectors located there and those 
at the ports of London and Liverpool. 
Fifth. In not a single instance have the inspectors of the United States 
Department of Agriculture been able to find a single case in the United States 
where the origin of the alleged cases were traced by the efficient system now in 
force for export cattle, and for the movement of cattle throughout the union. 
I think, gentlemen, from the overwhelming evidence here quoted, every 
word of which can be substantiated, that you will be convinced of the correct¬ 
ness of the diagnosis made by the American veterinarians stationed in this 
country, two of which, I am proud to say, are graduates of the American 
Veterinary College and members of your honored Association.
