THK PREVAILING EPIDEMIC AMONGST CATTLE, &C. 137 
12. I should say convalescent in from 4 to 7 days. 
15. There was either a partial or perfect cessation for a time, 
and in many cases not again returning in any thing like the origi- 
nal quantity. 
16. I have observed that store beasts in good heart bore it best ; 
very poor stock bore it badly : old cows suffered much, but the 
greatest danger existed with cows in full milk, or down calving. 
18. I have already stated that many of my patients did much 
better after it, and are still going on well, except in bad cases of 
lameness, or inflamed bag. 
19. I have not seen it sufficiently marked to satisfy myself here. 
I think there is much gross blundering. I have lately had two 
beasts tied up that had it in the spring, among many others that 
have suffered much. They have escaped — they ate and drank 
with the others. I think if we were to watch narrowly we should 
find but few instances indeed in which they have it twice. 
There is an opinion amongst many farmers, backed by some ve- 
terinary surgeons and medical men, that the milk from the diseased 
cow was the cause of the disease in pigs. I do not believe that it 
was to be thus conveyed. I know an instance of a lot of pigs that 
were bought purposely to give the diseased milk to. They were 
kept entirely upon it for six weeks, and not one suffered. No! 
They are affected by some external agent. I saw the fowls bad 
with it in one yard — and some died. I merely send you this little 
incident, because I know that you will attach the proper weight to it. 
To a man who suffers, at times, as you do, I cannot close this 
communication better than by saying, good health to you, and to 
all bipeds and quadrupeds that belong to you. 
ON THE PREVAILING EPIDEMIC AMONGST CATTLE, 
SHEEP, &c. 
By Mr. T. Mayer, V.S., Newcastle-under- Line. 
[The Mark Lane Express, of January the 25th and February the 
1st, contains two excellent letters from Mr. Mayer, sen., V.S., 
of Newcastle-under-Line, on the Epidemic prevailing among 
Cattle and Sheep, and written for that paper at the request of 
a noble and influential agriculturist in the county of Stafford. 
Whether we should have said all that he has done on certain 
points is a question which we will not agitate at present. The 
Essays are highly creditable to the writer, and to the profession ; 
and we most cordially recommend them to the perusal of our 
brethren. — Y.]
