EXPERIMENTS MADE AT THE IMPERIAL ACADEMY OF 
MEDICINE WITH THE COW-POX, AND OTHER ANIMAL 
VIRUS, PROM THE 12th OF APRIL TO THE END OF 
DECEMBER, 1866. 
By M. Depaul, 
Member of the Imperial Academy of Medicine; Director of Vaccination 
and Professor of the Faculty of Medicine of Paris. 
Before commencing these experiments, the commission 
minutely inquired into the origin of the cow-pox matter 
which it was about to use. There was only at its disposal 
that which had been imported from Naples, and had been 
used for several months by M. Lanoixj and though there 
was no cause to suspect its goodness or purity, the com¬ 
mission would have been pleased to find no objection to 
it. To arrive at a correct result it was resolved to offer a pre¬ 
mium and write a special note to country practitioners, when 
a fortunate chance put the commission in possession of that 
which was so ardently sought for. We have already shown 
what took place in the Department of the Loiret, and the 
means which were taken by the director of the vaccine 
department of the Academy not to lose this chance. 
Since the 30th of April we have had at our disposal the 
lymph from a case of spontaneous cow-pox from Beau- 
gency, where it had occurred. From that time it was the 
only lymph we have used; and which we have preserved 
without interruption up to the end of these experiments. 
Moreover, since the malady of the cow and the horse, which, 
communicated to man has produced the vaccine, the oppor¬ 
tunities of finding the cow-pox have not been so rare as was 
supposed. During our researches the following fresh oppor¬ 
tunity presented itself to us. A sister of the order of St. 
Vincent-de-Paul, lady-superior of an asylum for children 
situated in the commune of Epinay-sous-Senart, sent word to 
M. Depaul, on the 1st of December,'that one of the cows of the 
establishment was attacked with what, in all likelihood, was 
the cow-pox. The director of vaccination went the next day, 
2nd of December, and found that the cow had on its udder, 
in the vicinity of the teats, six pustules, but unfortunately
