PLEURO-PNEUMONIA IN CATTLE. 
my experiments. The experiment that I made at my own 
expense has now completed its course, and all the incon- 
veniences of my new method are overcome. These experi- 
ments, of which I shall give a detailed account further on, 
were continued successively upon 108 beasts, and all of 
them, to my great satisfaction, were preserved from the 
disease. In order to make a counter experiment, fifty beasts 
which had not been experimented on were distributed among 
the others, and of these fifty beasts seventeen became di- 
seased with pleuro-pneumonia. I shall give an account of 
this in a few words further on. Here then are stables that 
had never been free from pneumonic diseases since 1836, and 
which have been so from February 10th, 1851, to the present 
time. How can the singular circumstance of 108 beasts, to 
which the remedy had been applied, continuing free from the 
disease, while in the same stables, under absolutely the same 
conditions, placed indiscriminately among the others, of fifty 
beasts to which the remedy had not been applied, seventeen 
became diseased, be explained otherwise than by the efficacy 
of the remedy ? 
A particular and very important circumstance, which all 
fatteners will know how to appreciate, and to which I further 
call your attention, Sir, is that the beasts subjected to this 
treatment are in some way entirely safe from epizootic 
influences, and fatten better and more rapidly than those 
to w'hich the remedy has not been applied, although not 
diseased. 
Wishing to preserve the secret of my remedy, you will 
conceive, Sir, that I have not been able to make experiments 
beyond my father’s stables, which for the rest afforded me 
an ample field for the purpose. I may add, however, that 
my father’s head distiller, whose residence is between the 
stables of M. Nys, distiller, in which the disease always 
prevails wfith great intensity, having had two cows suc- 
cessively diseased in the same stable, asked me to administer 
my remedy to a third which he had just bought, and for 
which he dreaded the fate of the two former; I did ad- 
minister it : this cow has remained in a state of perfect 
health during the nine months he has had it. 
This, Sir, is a general view' of my experiments and success. 
I have succeeded in preserving my father’s stables from the 
disease during more than a year, w hile everywhere else around 
us it w r as raging with severity. This benefit which I have ob- 
tained for my father’s stables, I desire to see diffused through 
all the stables inBelgium and other countries. 
I shall now' give you the details of what I have done, and
