714 OBSERVATIONS ON THE LUNG PLAGUE OP CATTLE. 
In support of the last-named period three remarkable instances 
of the infection of new countries may be named. 
Norway ,—In 1860 some Ayrshire cattle were imported to the 
Agricultural College of Aas, direct from Scotland. Three 
months later some of them were noticed sick, and the country 
was only saved by the slaughter of all native stock with which 
they had come in contact, and the long seclusion of the sur¬ 
viving Ayrshires, so that danger of infection from them might be 
obviated. 
Australia .—In 1858 a short-horn cow that had been three 
months at sea was landed at Melbourne, and a fortnight later 
she manifested the lung plague. This was 104 days after ship¬ 
ment from Eugland, and the nature of the disease is only too 
sadly certified by the steady extension of the plague over 
Australia from the date in question. 
South Africa .—In 1854 a Dutch bull was landed at Cape 
Town after having passed two months at sea. Six weeks after 
his arrival he showed signs of lung plague, and from him the 
pestilence spread to the whole of South Africa, and still prevails. 
Here again was an interval of 104 days from the time of ship¬ 
ment in Holland to the first manifestation of the disease in Cape 
Colony. 
To these may be added some instances that happened under 
our own observation, and the first two of which are as clear and 
unequivocal as the instances above mentioned. 
In East Lothian, Scotland, in 1855, a farmer who had had 
his stock clear of disease for years, purchased a cow, which for 
three months after purchase kept in low condition, and occa¬ 
sionally knuckled over at the fetlock as if rheumatic, but fed and 
milked well. At the end of ninety days she was taken with 
lung plague, and conveyed it to all the cattle on the farm. 
There was no other lung plague in the neighbourhood, nor had 
there been for a length of time. 
Josiah Rogers, of Sag Harbour, Suffolk Co., N. Y., whose 
herd had been exposed by contact with a cow from an infected 
herd, but which did not herself show sickness, turned a cow out 
on the grounds of Montauk, April 28th, 1879. On August 10th 
she was found suffering from the lung plague, and was slaughtered 
in consequence. This was 104 days after she had left the home 
herd, and probably 110 or more after she had taken in the germs 
of the plague. The cow would not have been left to sicken on 
Montauk, but that she was entered in the name of Mr. Rogers' 
son, and her connection with an exposed herd thus failed to be 
recognised. Lour more of Mr. Rogers' herd suffered at home, 
and one after it had been sold and removed to Old Westburg, 
Queens Co., the sale having been made before we had any
