EPIZOOTIC PLEURO-PNEUMONIA 
the history of most of the cases that have occurred in this neigh- 
bourhood ; and in doing this, I hope to be enabled to adduce suffi- 
cient facts to enable the most sceptical to appreciate the infectious 
or non-infectious character of I his disease, and also to demonstrate 
the truth of the assertions, that pleuro-pneumonia was introduced 
into this country by Irish cattle. 
CASE I. — The disease first made its appearance in this neigh- 
bourhood in May 1843, at an extensive farm, called Scot’s-hall, in 
the occupation of Mr. C — , of D — . Mr. C. had purchased thirty 
year-old Irish cattle (steers) at Norwich stock market, in April. 
They were at the time in apparent health, and were sent to the 
marsh. About a fortnight after, one of them was observed to be 
unwell. He was taken home, and died. On the following day, 
upon a post-mortem examination it was evident that he died of 
pleuro-pneumonia. 
On the 11th of May a second was attacked, and by the 1st of 
June five others. The treatment of all was strictly antiphlogistic, 
and they all died, after from a few days to a fortnight’s illness. In 
an adjoining house, but separated from it by a yard and wall, the 
dairy cows, consisting of thirteen in number, were milked, and 
were at the time considered quite safe: however, on the 11th of 
June, one of them was attacked, and in a few days another. The 
Irish beasts were all coughing, and, on being closely examined, 
evident symptoms of pleuro-pneumonia were detected in nearly all 
of them. They, with the two cows, were immediately sent to 
another farm about a mile and a half distant from the marshes : 
every attention was here paid to their general comfort, and the 
medical treatment altogether altered, consisting of remedies similar 
to those advised in the following pages. Several of the Irish 
were many weeks in recovery and the two cows died. As se- 
veral of the other cows were evidently infected, Mr. C. deter- 
mined upon selling them all. They were accordingly sent to market, 
and sold. 
Mr. C. had twenty-four short-horns in another marsh, and his 
neighbours had also in the surrounding marshes cattle of all ages, 
but not a single one was attacked with this disease during the sum- 
mer. 
Case II. — Mr. G — , of H — Hill house, bought of a stock 
dealer at Norwich fifty-three two and a half year-old short-horns 
on July 15th, 1843. They were in excellent condition, and to all 
appearance in health; they were sent home to his farm, and, on the 
following day, down to the marsh. On the next morning one 
of them was found dead, and in the course of a fortnight six others 
were attacked. Being forward in condition, they were sold to the 
butchers ; but the lungs and chests of three of them were so much
