since, although the dams had been previously very severely 
affected. 
He had not known or heard of any newly-born animal having 
been affected, or of those that have sucked or otherwise ob- 
tained the milk of diseased cows. Some persons boiled the milk 
given to calves, which, probably, was a safe precaution. 
It has not appeared in the feet or elsewhere in young sucking 
animals. In one instance of a calf of nine months old, it had a 
very slight attack. 
It reduced them much in condition, but after they got well 
they laid on flesh very quickly. 
Not any of his horses were ill before, during, or since the 
cattle epidemic. 
It had not quite disappeared among the sheep at the begin- 
ning of March 1841, but there were no cases among the cattle 
and pigs for more than two months before. There were yet more 
than forty head of cattle and four hundred sheep on the farm 
which had not been attacked. They have been kept carefully 
apart from the infected portion of the stock. 
In conclusion, Mr. Jobson offers it as his firm opinion, that the 
disease is entirely inf ectious : he had not seen, in the experience 
which he had had with his own stock, or what he had heard of 
others, any cause to think otherwise. Wherever the animals 
have been kept carefully out of the way of diseased ones, or 
of persons who have been occupied among those which were dis- 
eased, they have been free from the complaint. 
The next Number will contain an account of the Epidemic in 
Durham, Cumberland, and Westmoreland; and Mr. Youatt will 
be thankful for communications respecting these counties.

The case of Mr. Bertie’s horse (Harkaway), which T sent you 
for insertion in the Number for December 1841, may be the means 
of eliciting some valuable hints from a few of your correspondents. 
At the time of writing the horse was very low in flesh ; and, after 
the ulcers before described had healed, he had an inflammatory
