333 THE LATE EPIDEMIC DISEASE IN SWITZERLAND. 
On the 10th of December a heifer, in a neighbouring village, 
that, three months before, had been pastured among some cows 
at Denezy, was taken ill, and, on being destroyed, was found to 
be infected with pleuro-pneumonia. In this animal the disease 
had assumed quite a chronic form. The lungs were of a whitish 
red colour, and the cellular spaces between them were filled with 
a clear citron-coloured serum. The bronchi were obstructed by 
white and red coagulations of blood. The vessels contained very 
small pale-coloured clots of blood. The stable in which this 
animal was, was immediately shut up, and still remains so. The 
contagion spread no farther there. 
On the 11th of December a cow, in a fifth stall, was taken ill, 
.and shewed every symptom of contagious pleuro-pneumonia. 
On the 22d and 23d of December six beasts were destroyed in 
another stable; and, lastly, on the 2d of January, 1841, ano- 
ther beast, in a seventh stable, was slaughtered, which proved to 
be diseased. A general slaughter of all the cattle in the village 
was now ordered, for the uninterrupted progress of the disease, 
and its extension, notwithstanding the utmost care and strictness 
in following up the police regulations, proved, too clearly, the 
necessity of this severe measure. The slaughter was not, how- 
ever, proceeded in with such haste as not to allow the cattle- 
owners time to derive some profit from the sale of the meat of 
those animals that were sound. The diseased ones were all 
buried. The skins were sent to the tan-pit after having been 
well prepared with lime. 
Of the seventy-six beasts which, at the time of the slaughter, 
belonged to the inhabitants of the village, fifty-one were sound 
and twenty-five were slightly diseased. Two calves had died a 
few days previously, but not of pleuro-pneumonia. The cattle- 
owners received a compensation of three-quarters of the value of 
a sound animal, and half the value of a diseased one. The 
stables were, after this, without exception, subjected to a 
thorough purification and fumigation. The plaster was all pulled 
down, the old wood burnt, and the new washed with the chloride 
of lime ; the litter taken away, every thing approaching to 
putrefaction carefully removed, and the walls washed with a 
fire engine. 
Beside the anatomical alterations which I have already 
described, and that were more or less apparent in every 
slaughtered beast, the veterinary surgeon who resided at Denezy 
remarked the following morbid appearance : — In many cases 
the chronic pneumonia was united with tubercles. In several 
of the animals the disease was in its first stage, and there it 
was found that the parts principally affected were the edges of
