578 THE LATE EPIDEMIC DISEASES OF CATTLE, &c. 
The milk was usually suspended, or thrown away for about 
ten days, and was then as good and as much as ever. It was 
once given to some pigs, and all of them became diseased. 
The sheep became diseased on the 24th of December. They 
still remain very lame, and, whenever there is frost without snow, 
it so cripples them that they become worse again, and those who 
have not previously had it keep falling. 
He has always found that, whenever stock have not got well 
scoured out by fruitful young grass in April and May, they have 
generally proved unhealthy some time during the forthcoming 
summer, particularly sheep during washing or shearing time. 
Sheep often swell after shearing, and especially when they have 
not been well physicked. 
Mr. R. Green, of Skillington, near Grantham, says that the 
epidemic first appeared in the second week in April, 1840, among 
some cattle of the steer kind in the straw-yard, and afterwards 
the swine in the same yard, and ultimately among the sheep. 
They had been driven to a fair at Grantham, about eight miles, 
but returned unsold. The epidemic made its appearance on the 
third day after. Not a single case had been previously heard of 
in the neighbourhood, and they were quite well before they were 
taken to the fair. They had travelled along a public road, 
and had likewise stood intermixed with other cattle. They 
were in the straw-yard, with a good open shed to go under at 
discretion. They were in good condition, had been fed with four 
pounds of linseed cake per day and straw, and were about three 
years old. 
It commenced by a foaming at the mouth, with a blistered 
tongue, on the third day, if we are to judge of them by their 
appearance and state. 
The disease commenced in the mouth, but soon afterwards ex- 
tended to the feet. They were chiefly of the heifer breed. 
The milk soon became greatly diminished, but, afterwards, it 
fully returned. He had two cases in which the heifers calved 
about four weeks before the usual time. Some of the cattle had 
cutaneous eruptions about their legs, and nearly the whole became 
lousy after their recovery. Those who had it mildly throve well 
afterwards, but the epidemic gradually spread through the whole 
of the flock, and remained about a month. 
Mr. Green had two farms about ten miles distant from each 
other. The cattle on the farm on which he resided escaped it 
until the autumn, but all had it afterwards, and generally in a 
milder form, except some that he had purchased, which had been 
driven, and probably caught cold as well as the disease. The
