PLEURO-PNEUMONIA IN CATTLE. 
I will now proceed to give a brief history of the disease 
from its commencement, together with a description of the 
stable or cowhouse in which the animals were kept. 
The owner informs me that in the spring of 1859 he im¬ 
ported, from the north of Holland, four cows. They were 
shipped at Rotterdam on the 6th of April, and arrived in 
Boston on the 23d of May. Two of these cows were in 
bad condition at that time, supposed to be from neglect on 
the voyage. They were transported from this city to the 
highland farm in Belmont, seven miles distant, in wagons, 
being unable to walk. One of their number died on the 
31st, eight days after its arrival, and a second on the 2d of 
June. 
Presuming that the only disease of these animals was 
prostration, induced by injuries or neglect on shipboard, the 
symptoms were not noticed, only that they had diarrhoea, 
and that their evacuations were exceedingly offensive. 
About the middle of June a third animal of this impor¬ 
tation was observed to feed but little in the pasture, and to 
absent herself from the rest of the herd, appearing dull and 
dejected. These symptoms were succeeded by a hard, dry 
cough, ears cold and drooping, grinding of the teeth, short 
breathing, rapid loss of flesh and strength, and as the dis¬ 
ease progressed, the breathing became more laboured, the 
animal making a sort of grunt at every respiration, and a 
fetid secretion took place from eyes, mouth, and nostrils. 
The respiration became more and more difficult, until in the 
last stage, when she stood with her nose elevated almost on a 
line with her back, and her mouth open, and thus she died, 
on the 29th of June, thirty-seven days after her arrival. 
The next one was an imported cow from Holland in 1852, 
consequently she w T as fully acclimated. She dropped a calf on 
the 2d of August, about tw’o weeks before her time, was taken 
sick on the 10th, and died on the 20th of the same month. 
Her calf is still living, and apparently in health, except that 
it has disease in the joints of the extremities. Under the 
influence of the Iod. Potass, externally and internally, it is 
improving. 
During this month (August) an ox and a calf showed 
slight symptoms of the disease, but not an entire loss of 
appetite, and they both recovered. 
About September 1st five or six animals were taken in the 
same manner, and in quick succession several others. During 
this month and the early part of October there were from 
five to ten sick all the time, and nearly all these cases 
proved fatal, twenty-four having died, and only eight, which
