ON THE RESULTS OF THE INOCULATION OF CATTLE 
FOR EPIZOOTIC PERI-PNEUMONIA. 
Report addressed to the Prussian Government, 
By Dr. C. Ulrich, Veterinarian of the Circle of Urietzen sur 
l’Oder ; Professor at the Royal Academy of Maeglin. 
On the 26th of August, 1852, Dr. Ulrich, commissioned by 
his Government to go to Cologne, and into Belgium, to make 
observations, on the spot, of inoculations for peri-pneumonia, 
(or pleuro-pneumonia), arrived thereon the 5th of September 
following, and immediately put himself in communication 
with Dr. Desaive, inoculator for the district of Cologne, and 
with the Provincial Veterinary Surgeon, M. Sticker, who 
being himself employed by the Prussian Government in the 
same pursuit with Desaive, assisted in the present investiga- 
tions. Dr. Ulrich likewise was in communication with Dr. 
Willems at Hasselt, and w T ith M. Verheyen, Director of the 
Royal Veterinary School at Brussels. His researches led 
him to the following conclusions : 
1. It is an established fact that, in many stables wherein 
peri-pneumonia had raged for several years, as well as in 
others which had only been infected by it of late, the disease 
disappeared shortly after inoculation. 
That, on the other hand, cases have occurred in w T hich 
the disease has continued to rage after and in spite of inocu- 
lation. 
2. In many cases of beasts dying afterwards of the disease, 
inoculation has not proved successful. 
At the same time there exist examples to the contrary: 
animals with w T hom inoculation has quite succeeded, and yet 
for all that, they have become afterwards the subjects of the 
disease. 
3. Cases have occurred wherein inoculation has proved 
without effect on beasts already in a state of convalescence 
from the" disease. 
And others have occurred wherein inoculation has proved 
equally successful, notwithstanding the subjects were in a 
state of convalescence. 
Others again have presented themselves wherein inocula- 
tion has failed to take any effect on beasts, either before or 
after this operation.
