84 ON THE EPIZOOTIC DISEASES OF CATTLE, &C. 
and weak, and her pigs were exceedingly small and unhealthy, 
and most of them died. All the sucking calves, as well as all calves 
fed on the milk of infected cows, throve well. The feet of the 
ewes were often exceedingly troublesome : they may appear to 
heal, but they break out from time to time; and, often, a fortnight 
passes away, and they are almost as lame as at first. If the dis- 
ease does not speedily pass over, the sheep are apt to lose (as was 
the case with Mr. Guy) all the condition which they had pre- 
viously gained, and his kyloes, which had been fed upon Swe- 
dish turnips and oil-cake during the winter, were not falter than 
when they took the disease four months before. 
Mr. Guy concludes by stating, that, although this malady 
seems to be highly contagious when a diseased animal comes in 
contact with a sound one, and feeds on the same pasture, or pas- 
ture that has been trodden upon by infected cattle, and although 
the principle of infection seems to be in many cases conveyed 
by the atmosphere, yet there is a great deal of caprice about the 
matter. In his farm two large lots of hoggets were divided from 
each other by a thin hedge, and those on one side of the hedge 
were plainly infected, yet three weeks passed, and the disease 
was not communicated. He knew also of several cases in which 
the ewes escaped, while the hoggets were affected. In other 
situations the contrary occurred. 
Another agriculturist, of the name of Hunt, and living in the 
same village, likewise communicated with the Agricultural So- 
ciety. He says, that there cannot be much difference with re- 
gard to the soil, but there may with respect to the general treat- 
ment and some other particulars, of which at first we should 
scarcely dream. Mr. Hunt had seventy-six head of cattle, in all 
but four of whom the symptoms were very mild. They first ap- 
peared at the latter end of October, three months before they were 
developed in the stock of Mr. Guy. The milch cows were earliest 
affected, and, after that, the fat cattle began to fail. It spread 
through the whole herd, with the exception of four beasts. It 
was a damp situation in which the cows were when they first took 
the disease, but all the young cattle were in the fold-yard when 
they were attacked. 
The weather on the first appearance of the epidemic was moist 
and damp, and the wind N.E. His cattle had no communica- 
tion with any others. They never travelled along any road, or 
were hurdled in any place where diseased cattle had previously 
been : but they were attended by a person who was employed 
among cattle, and whom he much blamed for bringing the infec- 
tion into his yard. This patient was the first cow in which it
