A NEW MEMOIR ON PLEURO-PNEUMONIA. 93 
happened at M. Vanstraelen’s, distillers. In the month of 
May, the stables of M. Vanstraelen were ravaged by pleuro- 
pneumonia ; inoculation was introduced, and fifteen days 
afterwards there was not a single case of sickness. For 
three months inoculation continued to be practised, and for 
three months his stables were free from disease. About a 
month ago, M. Vanstraelen purchased 20 beasts, not ino- 
culated, and put them along with his own inoculated ones. 
Three weeks afterwards, pleuro-pneumonia appeared in one 
of the new purchases, and on the 10th of September it was 
destroyed by order of the authorities. The same day, M. 
Vanstraelen had the remaining 19 inoculated. I shall again 
rest my assertion on what took place at the Chateau de 
Hirkenrode ; and lastly, at the farm of Dumoulin, then at 
his brother’s, who, residing at twenty minutes’ walk from the 
town, has had, of 7 beasts he possessed on the 24th of August 
last, 6 attacked with pleuro-pneumonia. All these experi- 
ences go to confirm my proposition. 
C£ And now, Sir, I will offer to your notice some fresh 
observations, showing my procedure of inoculation to be 
preservative against epizootic pleuro-pneumonia. 
“ On the 25th of July, pleuro-pneumonia broke out at the 
Chateau de Hirkenrode upon an ox: it was killed by order 
of the authorities; and the following morning 16 others were 
inoculated in the dewlap, and 2 in the tail ; since which no 
beast has contracted the disease. 
“ At Bovendans, a famous inn ( auberge ) in the neighbour- 
hood of Diest, there were 23 beasts ; and for several years 
they had known nothing about pleuro-pneumonia. On the 
20th of June, 1852, the disease broke out, and on the 7th 
of August, at the instance of M. Mommein, V. S. of the 
government at Warck-la-Ville, I went thither, and, on my 
arrival, learned that 4 beasts had died of pleuro-pneumonia, and 
that 3 others while suffering from it had been transferred to 
the butcher. I also found five others in the stable in the 
last stage of the disease. I caused one of the sick to be 
slaughtered, and took from it some virus, with which I 
inoculated those still remaining. On those that were sick 
already, according to M. Mommein and the people of the 
house, the inoculation took no effect. Two days after ino- 
culation, 2 other beasts fell sick ; and on 11 the pneu- 
monia of inoculation became manifest. So that of the 23 
beasts of this establishment, 9 died from the disease, 3 were 
given over to the butcher, and 1 1 were saved by inoculation, 
though unfortunately late in its application.
