ROYAL VETERINARY SCHOOL AT LYONS, 1841 - 2 . 393 
have furnished us with the means of studying the diseases of 
cattle. Beside this, the clinical professor, assisted by several 
pupils, has been attending a flock of 120 sheep that were suffering 
from fly and foot- rot. 
The agriculturists of Lyons do not keep many pigs ; neverthe- 
less, 38 of these animals have been brought to us, and eight have 
been castrated with success. 
Rabies — Internal Pathology. 
Several experiments made with regard to the contagiousness of 
this disease have been attended with results different from those 
already known. They tend to prove that this disease can be com- 
municated in sheep to the fifth generation. This is contrary to 
the conclusions of some medical men, who state that its contagious 
properties are becoming rapidly extinct. These facts enable us 
to establish and confirm several important points. 1 st, That the 
saliva of the dog can communicate rabies to sheep, but that that of 
the sheep cannot communicate it to carnivorous animals. 2d, That 
these small ruminants are not able directly to communicate rabies 
to individuals of their own species, because their peculiar dental 
system does not admit of their bile producing inoculation. 3d, The 
part to which the virus is applied is by no means indifferent. 
Whenever experimentalists have failed several times in producing 
the disease, it is because they have inoculated some part of the 
body which is not capable of absorption. 
The face, lips, and round about the mouth are the parts that 
should be inoculated ; but experience proves to us every day how 
dangerous bites are on these parts. 
During this year rabies has appeared very frequently at Lyons. 
Eight persons have died in consequence of the bite of rabid dogs. 
Energetic measures have been taken by the municipal authori- 
ties, and three thousand vagabond dogs have been destroyed. The 
school never received so large a number of hydrophobic patients ; 
62 out of the 104 dogs that died in the hospital were rabid. It is 
not easy to assign any cause for the frequency of this dreadful 
malady. 
In 1842 rabies appeared under an enzootic form, not only in this 
town, but also in Aix, Nismes and Rouen, in different climates, at 
various epochs, and under opposite atmospheric circumstances. It 
was, however, in J une last, when the heat was greatest, that the 
cases were most numerous. Up to the present time it was believed 
that one of the most active causes of rabies was variation of tempe- 
rature, and especially a sudden transition from an elevated tempe- 
ture to cold rain.
