ON THE EPIZOOTIC DISEASES OF CATTLE, &C. 83 
days later than the cattle, and may be said to be suffering yet, 
though he has had no new cases for a fortnight. 
The disease may be said to have disappeared from his farms 
about the 28th of January. 
His farms are situated in the township of Chiswick, parish of 
Arcroft and county of Durham, on the sea coast, five miles from 
the mouth of the river Tweed. There are extensive salt marshes 
to the south-east, about three miles distant, and some low and 
wet marshy grounds about a mile to the south and east ; but no 
marsh, pond, nor river, and very little water of any kind, is upon 
his farms, which contain about six hundred acres. 
We proceed in a southern direction to the county of Northum- 
berland and the parish of Kirk Newton. Mr. G. A. Guy has a 
considerable farm there, rather hilly, dry, open, and undulating; 
a turnip loam, with gravel and some clay, but no marshes. 
The weather mild, with light southerly winds. No direct com- 
munication with any other sheep and cattle ; but the supposed 
infection was as follows : — 
On the 30th of January the sheep-flock was removed for two 
days to a part of the farm on which there was a flock of diseased 
sheep, three-quarters of a mile to the windward of them. His 
flock was divided into parts, in one of which the disease broke 
out on the third morning, and in the other on the fourth, and 
then pursued its path through both alike. The cattle were like- 
wise affected. The mouths and tongues of the cattle were the 
worst, and the feet of the sheep. Animals are rarely attacked a 
second time by this disease, except that the sores on the feet of 
the sheep do frequently break out afresh. 
Salts, with sulphur and nitre, were given both to the cattle 
and sheep. The mouths of the cattle were washed with a solution 
of alum, and a caustic preparation used for the hoofs of the 
sheep ; but in no instance did the sheep that were thus treated 
recover more quickly than those that were left alone. 
Mr. Guy did not lose a patient, but his flock was much reduced 
in condition, and some ewes could not stand for three or four days. 
In some instances his neighbours’ and his own cows yielded their 
milk in the usual quantities — in others it diminished, and almost 
disappeared while the cow was in any considerable state of fever ; 
but there was no case in which the milk did not return when the 
cow recovered. 
There has seldom been any case of the produce of females 
labouring under the disease seeming to be much affected ; but a 
sow that was very ill some time before farrowing, continued poor
