92 A NEW MEMOIR ON PLEURO-PNEUMONIA. 
“ I have the honour of repeating, Sir, that the following 
two authentic facts, duly proved and received by MM., the 
members of the Committee, are acquired by science. 
“ 1. On the 23d of July, two cows suffering severely from 
pleuro-pneumonia, were placed, at the request of the Central 
Committee, in my father’s stables along with a Durham bull, 
two Dutch oxen, a Dutch cow, and two oxen of our own breed, 
all previously inoculated. These two beasts succumbed 
standing by the sick, though others were in health, after a 
cohabitation of seven days and seven nights ; they remained 
after death for a certain time where they stood, and yet all 
the inoculated cattle remain in the stable up to this very day 
in a state of perfect health. 
“ 2. Two inoculated cows were put, on the 27th of July, 
at the request of the Committee, in a fomes of infection 
of pleuro-pneumonia, on the farm of Dumontier, where, 
of 17 beasts, 13 had already contracted the disease. These 
cows were at first mingled with such cattle as had already 
had the disease, where they were placed along with 7 
who were suffering at the time for a couple of days, and 
lastly, amongst those that were convalescent. These cows 
are there still, and remain in excellent health. They were 
carefully examined on the 2d September by the honorable 
English professors, MM. Simonds and Morton, sent to Hasselt 
for the purpose of studying the phenomena of inoculation. 
“At the Veterinary School of the State, divers experiments 
have been instituted and regularly pursued, which will not 
be long before they confirm the happy results which already 
have been obtained in other quarters. 
“ At the present day, pleuro-pneumonia has departed from 
the town of Hasselt. It has not vanished through chance, 
as some persons would have us believe, — it has ceased as the 
effect of the inoculation that has been practised, and by 
inoculation alone have we been delivered from the pest ; 
since beasts not inoculated, left among such as have been 
inoculated, have at different periods contracted the disease : 
these facts have transpired principally at MM. Jean 
Fanvinkeroye and Nys, distillers. At M. Nys’, of 32 
inoculated beasts, 17 have contracted pleuro-pneumonia; while 
260 beasts have been subjected to inoculation since the 
29th April, and not one of these last have been touched by 
the plague. M. Fahrz, distiller, has had a beast sick for 
three weeks, and M. Thiers for ten days. 
“ It has proved still more that what I say here is the fact 
that has taken place at M. Rousseau’s, 'which I mentioned 
before ; and I am now going to relate to you what has
