272 THE LATE EPIDEMIC DISEASES AMONG HORSES, &c. 
been lied up six weeks without any previous indication of mis- 
chief, failed. In other cases attempts were made to commu- 
nicate the disease both to cattle and sheep, particularly to some 
cows in calf, by putting them together, and also by the food that 
had been placed before diseased cattle being given to them. He 
had some black-faced sheep three months, that were selected 
from a lot bought from a northern fair : they were driven home, 
and not a single individual became ill, but the remainder fell 
amiss the very day after they were selected. “ In fact,” adopt- 
ing the language of Mr. Rutson, “ I could not find any satis- 
factory account of the cause of the complaint.” It was a truly 
epidemic disease. 
Mr. Booth, of Killerby, Catterick, Yorkshire, in a hilly dry 
situation, screened with belts of plantation, the surface soil 
loam, the substratum gravel, had his share of the disease. There 
was no possible communication with other cattle. About a fourth 
of the number were out of doors— the rest housed. The frost was 
severe, but the animals were in good condition, and were fed on 
turnips and straw. The disease commenced with the young cat- 
tle, after which it spread indiscriminately. There was loss of 
appetite, blistered tongue, and stiffness of the limbs. The fat 
and heavy animals suffered materially in their feet. IN one were 
affected a second time. The beasts were fed on turnips and hay, 
and the medical treatment employed was that recommended by 
Professor Sewell. No deaths occurred. When the udder was 
not affected, the milk generally returned in its usual quantity ; 
but when the udder had been diseased or ulcerated, the flow of 
milk sometimes ceased altogether. The other diseases of cattle 
retained their usual character. Abortion in one case followed 
the disease. The malady has not appeared in the feet of sucking 
animals, nor were there any cutaneous eruptions before or after 
the disease. From violent attacks of the malady there was often 
great loss of condition. The usual duration of the disease was 
about five weeks from the commencement. 
Sir Godfrey Webster gives an interesting account of his cattle. 
His ground at Woolley Park, near Wakefield, is rather flat, yet 
somewhat elevated — the situation dry and well wooded. It is 
altogether a healthy locality. His cattle had not been in com- 
munication with any others. The disease made its appearance 
first in a lot of West-Highland heifers, three years old, on the 14th 
of January 1841. It extended to seven store pigs in the yards,
