FARCY IN CATTLE. 
567 
Having the opportunity of instituting several experiments, I 
determined that I would satisfy myself with regard to the conta- 
giousness of the disease. 
June 20 th, 1826. — 1. Having shaved off the hair in certain 
places, I applied to the skin of two cows the matter taken from 
the buttons of other cattle that were farcied. No disease was 
produced. 
2. June 24 th. — I, with a lancet armed with the virus, punc- 
tured each side of the neck of an ox nine or ten years old, and 
very poor. Not the slightest eruption followed. 
3. July 10 th . — I repeated this experiment on two other cows, 
but without effect. 
4. July 28 th . — The same experiment was made on an aged 
mare in tolerable condition. She was punctured in various places, 
but without success. 
5. Aug. 1st . — By means of a lancet, I inoculated a lamb and 
two dogs with the farcy matter, on the inside of the thigh and 
on the fore-arm. The result was the same as in the other ex- 
periments. 
To these were added other experiments as to the stabling, and 
working together of the sound and the diseased. No bad con- 
sequence resulted. 
It appears, then, that this species of farcy is not contagious, 
with regard at least to many species of animals.

[These two essays possess much interest — -the diseases related 
in the first had many of the characters of equine farcy : there is 
considerable similitude to that malady in the cases recorded in the 
second communication. The identity, however, is doubtful. 
The farcy diseases, and farcy humours as they are called by many 
veterinarians, require a more accurate classification than they 
have yet received. Will some of our correspondents take this 
subject up ? — Y.] 
HISTORY OF A CASE OF PLEURISY WHICH PRE- 
VAILED ENZOOTICALLY IN A FLOCK OF SHEEP 
IN THE DEPARTMENT OF THE LOWER SEINE. 
By M. Seron, M.V. 
I was called on the 30th of January, 1836, to a sheep-fold on 
which some unknown disease had been committing dreadful ra- 
vages. On my arrival one of the sheep was dying : I stayed and 
opened him, and thought that I perceived the cause of death. Of
