CATTLE PESTILENCE.

always saw with regret the massacre of their cattle ordered 
by the veterinary surgeons, complaied loudly. From the 
instant in which the disease was declared non-contagious, the 
cordon sanitaire and the sacrifice became an useless and ruin- 
ous measure. Prince Stephen, the Govenor-General of 
Bohemia, was from that time led, if not to suspend, at least 
no longer rigorously to sustain, the execution of sanitary 
measures. 
Immediately, the disease, which had been confined within 
a narrow space, invaded the whole of Bavaria, causing 
enormous ravages; and the Government of Vienna, placing 
but slight confidence in the discovery of the doctors, sent to 
the other districts affected the learned director of the 
Veterinary School of Vienna, with extended powers ; and 
this person having stated and declared that the disorder 
was certainly the contagious typhus, the usual measures 
were re-established with great severity. The disease 
was instantly arrested, and rapidly disappeared. The French 
veterinarians, who arrived at the moment at Prague, on their 
return from Moravia, being consulted by the local govern- 
ment, had no hesitation in declaring themselves of the opinion 
of their brother surgeon, in approving the energetic resump- 
tion of isolation and slaughtering. 
This epizootic of 1844-5, which destroyed a million of 
cattle in Russia, and caused considerable losses in Gallicia, 
Moravia, Bohemia, and Lower Austria, did not enter upon 
any point into France, Saxony, or Bavaria, so near as were 
their frontiers, thanks to the sanitary measures prescribed by 
these several states, and enforced by them with great severity ; 
which is a further proof of what cannot be too often repeated, 
that the typhus is not an epizootic developing itself like the 
scab, cholera, or plague, under epidemic influence or any 
medical constitution whatever, but a disease extending itself, 
and only capable of extending itself by means of contagion, 
which all the observations made up to this day tend to 
establish by the most conclusive evidence. 
This is a truth so much the more important to repeat, in 
that it follows from it that a country threatened might always 
secure itself against it by closing up all the avenues of 
contagion. 
Some years later — in 1856 — we again entertained fears, in 
France particularly, in consequence of the Great Exposition. 
M. Renault and M. Imlin returned into the east of Germany. 
There they stated, after having pushed their investigations 
into the heart of Hungary, that the epizootic had been 
devastating that country ever since 1849* It had been intro-
