414 PRIZE ESSAY: — PLEURO-PN EUMON IA AMONG CATTLE. 
were observed to have a cough from the first, and about a fort- 
night after one died of pleuro-pneumonia. The cow bought of the 
dealer soon after died of the same disease. And on the 9th of 
January, 1848, the other cow was taken, and died on the 28th of 
the same month. 
Case 16. — Mr, S. purchased in 1845 ten head of stock at a fair : 
all were observed to cough or husk more or less. Shortly after- 
wards six became decidedly affected with the disease, and five 
died. This is a very healthy and well conducted farm, containing, 
on an average, from twenty to thirty head of cattle. 
Case 17. — In September 1844, Mr. F summoned us to attend 
some young home-bred stock, which he had reason to think were 
suffering from the epizootic pleuro-pneumonia. They were con- 
fined in a close and ill- ventilated hovel. All recovered. The 
manner in which they first became affected is not known. 
Case 18. — In March 1844, Mr. F., milkman, of Cambridge, had 
nine cows, and in the same month they were all observed to have 
a cough ; and one, which eight months before he had purchased of a 
neighbour, became attacked with the disease, and, thinking it to be 
the garget,” waited three days before we were called in. She 
was attended for three weeks, and died. About a fortnight before 
Christmas in the same year, he bought another cow of a jobber at 
St. Ives’ market, which also died of the same disease in six weeks. 
A few days after this he bought two more at Bury market : one 
was taken, and died in three weeks, and the other within a month. 
He then purchased two more cows of a person about a quarter 
of a mile distant, and, fearing if these were taken home they might 
catch the disease, he requested that he might milk and graze 
them on the person’s premises, which had hitherto escaped the 
malady. This was readily granted; but they, too, became 
affected with the disorder, and died, after being treated for about a 
fortnight. Several others on the same premises were immediately 
attacked ; some died, and some were slaughtered. Between this 
period and January 1848, eight more have died of the same dis- 
order. Mr. Fletchers premises stand in a low and confined lo- 
cality, and until very recently had never been drained. 
Case 19. — In the latter end of August 1846, Mr. W., who 
farms between four and five hundred acres of land in a low marshy 
district, situate on the banks of the Cam, purchased nine steers at 
an extensive stock-market in the neighbourhood, all of which 
were observed to cough shortly afterwards. He kept them for 
about a month, and, perceiving no improvement, exchanged them 
for nine heifers with the same dealer. These were also noticed 
to cough in a few days; and on the 12th of October one of them 
died of confirmed pleuro-pneurnonia. All the remainder were 
more or less affected ; and, after having been removed into a warm
