PLEUROPNEUMONIA. 
which were obtained during an inquiry in 1867, are ad- 
duced : — 
A young bull, in a farm adjoining one in which there were 
diseased cattle, broke through a hedge and got among the in- 
fected animals. He was immediately driven back to his 
owner’s premises, and in three weeks afterwards exhibited 
the usual symptoms of pleuropneumonia. In another case a 
farmer bought six Irish cattle about the end of July, and put 
two of them on his farm with his stock. A month after the 
introduction of the two Irish cattle, one of them was attacked 
with pleuropneumonia; one of the original stock was next 
attacked, and the disease continued to spread until by the 
middle of December twelve animals were affected, of which 
six recovered. The four Irish cattle which were sent to 
another farm did not suffer, and it is therefore probable that 
only the one which was first attacked came from an infected 
herd. 
Another stock-owner in the same district bought some 
Irish cattle in June. One of them was attacked with pleuro- 
pneumonia a month after purchase, and the disease quickly 
extended through the herd. 
The next case occurred also in an Irish cow; but as the 
animal was bought in May and did not show any signs of ill- 
ness until September, it is hardly likely that she introduced 
the disease: it is nevertheless true that she was first attacked, 
and after her death seven cows of the original stock became 
affected in succession. Four of them died, two recovered, 
and one remained ill from the effects of the disease at the 
time of the inspection in December. 
Another instance is worthy of notice, on account of the 
entire recklessness which was displayed by the stock-owner, 
or the servants, after the outbreak of disease had been recog- 
nised. A dairyman, who possessed six cows, purchased an 
Irish cow, in August. The anima was attacked with pleuro- 
pneumonia in October, and was put in a place by herself, 
but, for some reason which could not be explained, the food 
and gruel which the sick cow left unconsumed were given to 
one of the six cows which formed the original stock. This 
animal at the end of three weeks showed characteristic signs 
of pleuropneumouia, and the disease extended to the re- 
maining animals. Four of the animals recovered, two were 
slaughtered by the butcher, and one remained ill at the time 
of the inquiry. It is quite possible that the Irish cow com- 
municated the disease to the animal which was next attacked 
before she was removed; but the proceeding which was adopted 
in reference to the refuse food was not the less reprehensible.
