94 A NEW MEMOIR ON PLEURO-PNEUMONIA. 
pneumonia broke out on the 10th of August, in the stables of 
M. Strootbants. One beast died. M. Strootbants’ son, 
studying medicine, came to me on the 16 th of August, and 
the next morning he inoculated his beasts, and pleuro-pneu- 
monia appeared no more. From this time numbers of beasts 
in the neighbourhood were inoculated, among others those of 
Baron DOverschie. 
“ At farmer Dumoulin’s, of whom we have already spoken, 
pleuro-pneumonia ceased ten days after inoculation. Four 
beasts, in good condition, remained well; and of 13, four 
became re-established, and nine have either died of the 
disease or been delivered over to the butchery. 
“ At farmers Marechal and Mans, at Yrage, when the 
Minister of the Interior did me the honour to send me to 
make inquiries as to the results of inoculation, no inoculated 
beast, nor any that had shown the local phenomena of inocu- 
lation, has contracted pleuro-pneumonia ; while there are 
some who have been inoculated, but in whom inoculation 
has not produced local manifestation. These facts were 
attested by M. Renier, V. S. of the government at Waremme, 
and by MM. the veterinarians Coene and Janne, who accom- 
panied me. 
“On the 25th of August I had the honour of receiving M. 
Lefour, Inspector-General of Agriculture in France, who 
narrated to me a fact which, in his mind, was conclusive: — 
M. Decrombecque, agriculturist at Lens, (Pas-de- Calais,) 
has obtained happy results from inoculation. For a great 
number of years the stables of this large proprietor had been 
ravaged by this pest ; while this year, thanks to inoculation, 
he has not a single case of the disease. 
“ On the 29th of August I received a letter from M. De- 
crombecque himself, confirming the success of inoculation, 
which had been communicated to me by M. Lefour. 
“ Everywhere, Sir, it is the same, of which I could mention 
many parallel facts. Everywhere, where I have introduced 
my method of inoculation, and have continued its use for 
three weeks, pleuro-pneumonia has invariably ceased. It is 
impossible to cite a case to the contrary. 
“ I have the honour of reminding you still of a very im- 
portant point. Inoculation affects young animals through 
lesions much less marked than animals advanced in years. 
Therefore it becomes more advantageous to inoculate young 
subjects, which, in case of accident, are of less value, who 
suffer less, and w ; ho are equally preserved by the inoculation. 
Thus w r e obtain the experience of a Dutch farmer, who had 
never seen pleuro-pneumonia in his stables, whilst his neigh-
