the distinguishing symptoms between it and tuberculosis. He 
said he was very much pleased to be present, but would not at¬ 
tempt anything like a full description of the disease, but would 
give a few points in regard to the disease. 
Most veterinary surgeons have had very little experience with 
the disease, and it was embarrassing to those to go into a herd of 
cattle and examine them, and give a definite opinion, especially 
when the disease exists in a chronic form. 
He went on the force five years ago in New York, and found 
it very difficult to pick one or two out of a large herd, affected 
with the chronic form, when not able to learn the previous history. 
In the acute form of the disease there was a high temperature, 
hurried respirations, and other evidences of acute lung trouble. 
Then it was not hard to diagnose ; but when these symptoms 
were absent, as in the chronic form, it was much more difficult. 
In the chronic form the examiner can only rely on auscultation and 
percussion, and the history. It requires constant practice to be¬ 
come an adept in the examination of the chest. 
In Illinois he found the disease in the acute form, but in Ohio 
had only found it in the chronic form. In tuberculosis there is 
cough, mucus in the bronchial tubes, and the lungs more resonant. 
The glands are enlarged two or three times their natural size. 
Acute cases seldom recover. 
In pleuro-pneumonia contagiosa, the lung is hepatized more or 
less, witli loss of respiration in such portions. Clear history, etc. 
Sometimes it is not safe to give a definite opinion in the chronic 
form, where you cannot get the history, until you kill an animal 
and hold a post mortem. Was pleased to see so many veterinary 
surgeons in this State and it afforded him great pleasure to see 
so many present. He felt sure for intelligence we would yield 
but little to our sister profession. Each one in the veterinary 
profession has a duty to perform which is equal to those in the 
sister profession in regard to contagious disease. 
This is one of the greatest stock-raising countries in the 
world, and he hoped it would never become ravaged to any great 
extent with the above disease, or any other contagious disease. 
We are dependent upon the veterinary surgeons throughout the
