THE LATE EPIDEMIC DISEASE IN FRANCE. 
once; and M. le Chevalier, at Osmanville, asserts that one of 
his had been attacked a second time, but very slightly. Never- 
theless, neither the one nor the other called in a professional 
man, although the case, if it existed at all, was well worthy of 
being examined and recorded. 
These gentlemen are perpetually changing their cattle. In 
1840, the epizootic had begun to attack them ; in 1841, it began 
again to rage, but among their new cows, that had been put 
with the old ones. Have they mistaken one of the new ones for 
an old one ? They pretend that they have not. Or might they 
not take for a second disease that affection which remained after 
the first had been badly cured ? 
MM. Poissy and Lebourgeois, already referred to, are also 
continually changing their cows ; but they have not mentioned a 
single case of a second attack. They have, however, recorded 
that all their cows which were not ill in 1840 were so in 1841, with 
the exception of one of M. Poissy’s, that has been twice spared. 
On the other hand, the dealers in calves and heifers affirm 
that they have had several who have been attacked by this 
disease two and even three times. 
Some of these cases, however, have not been stated with much 
accuracy, or positively ; and, besides this, the length of time that 
has passed since the commencement of this disease is much too 
short to enable us to give a positive opinion on the subject. 
Time alone can resolve the question. 
The Character and Progress of the Disease 
in Switzerland. 
An interesting communication from M. De la Harpe, M.D., 
of Lausanne, enables us to trace this disease, and to mark its 
character and treatment in Switzerland. 
M. De la Harpe is supposed to be speaking : — 
In the month of February 1840, the disease shewed itself in the 
village of Villars le Comte, in the neighbourhood of Moudon. 
Previous to that time it had not been recognised, nor had the 
authorities been apprised of its existence, partly because the 
animals were attacked one after another and not simultaneously, 
and partly because it did not make a decided appearance until 
several weeks after the animal had become infected. During 
February many cows fell victims to this malady, and the flayer, 
or skinner, found in them all traces of inflammation of the chest.
