PLEURO-PNEUMONIA IN CATTLE. 
been given to it ; but it is now well known to all who attend 
to such matters, by the name of “ Exsudative Pleuro- 
pneumonia,” a denomination properly applied to it by a 
learned Belgian professor, M. Gluge. 
You know, Sir, that Hasselt is unhapily distinguished for 
having always a large number of beasts affected with pleuro- 
pneumonia. This disease was introduced to us from Flanders 
in 1836, by some beasts purchased of the merchant Moras, 
and first brought to my father’s stables, and to those of 
M. Platel, distiller. From that time to the present, all the 
distillers have suffered considerably by it, and many small 
farmers have been entirely ruined. The disease, at first 
epizootic amongst us, has become enzootic, and decimates a 
considerable number of beasts of the bovine race every year. 
Terrified and grievously affected at the sight of the almost 
daily ravages committed under my eyes upon beasts affected 
in the highest degree with pleuro-pneumonia, and injured, 
moreover, in my own interests, I considered it my duty, for 
the sake of humanity, for the advantage of my fellow-citizens, 
and for my own interest, to apply myself to the study of a 
disease of which a permanent focus of infection was in ex- 
istence near to me. 
Physician to mankind, I have drawn from medical science, 
as applied to man, whatever information it could afford on 
this matter, upon the same science as applied to animals. 
I have studied the disease under all its phases, its nature, its 
causes, its symptoms, its treatment. I have submitted 
animals to various known and cried-up methods of treatment; 
and have myself ventured to try many new medicaments. I 
have found, among others, the Hack suVphuret of mercury of 
remarkable efficacy, in doses of from two to three drachms, 
in twenty-four hours, accompanied by half-a-drachm of 
calomel ; the whole suspended in a thick mucilage of gum, 
and administered, above all, at the first stage of the disease. 
Of twenty-three beasts which I treated by this method 
nearly a year ago, I cured fifteen. I beg the veterinary 
doctors to follow my example in the use of this medicament. 
The idea of employing it struck me from my studies and 
* researches upon the nature itself of the disease, which I con- 
sider to be a general disease ; a disease in which the blood is 
vitiated, either primitively, or in consequence of the lesion of 
the lungs, which is always constant — always the same — 
always that remarkable marbled hepatisation. I have tried 
many preventive measures ; but I shall speak of all that — in a 
memorial which I am preparing upon pleuro-pneumonia, and 
which I shall address to the proper authority. At present.
