2d. Ten of these shall receive no treatment and be kept as 
proofs. 
3d. Twenty-five shall receive two vaccinal inoculations from 
twelve to fifteen days apart with carbuncular virus. 
4th. These twenty-five sheep will, with the remaining twenty- 
five, be inoculated twelve or fifteen days after with very violent 
virus. 
The unvaccinated twenty-five sheep shall all die, the twenty- 
five vaccinated shall resist the disease, and will afterwards be com¬ 
pared with the ten reserved as proofs, so as to demonstrate that 
the vaccinations have not prevented them, after a certain time, 
from returning to their normal state. 
5th. After the inoculation of the very violent virus to the 
two series of twenty-five vaccinated and unvaccinated sheep, the 
fifty will remain in the same barn ; one lot being distinguished 
from the other by a mark made on the ear of the twenty-five 
vaccinated. 
6th. The ten reserved for proofs always to remain by them¬ 
selves, so as not to be exposed to the contagion of the diseased 
ones. 
7th. All the sheep which shall die to be buried one by one 
in separate spots, close to each other, and situated in a fenced 
plot. 
8th. In the month of May, 1882, twenty-five new sheep— 
that is, not having been experimented upon—shall be placed in 
said plot. 
When these twenty-five sheep shall have eaten the grass of 
that ground, they will be fed on the same with grass thrown upon 
it. Of these, several will become spontaneously affected through 
the carbuncular germs which shall be brought back to the sur¬ 
face by the earth worms, and shall die with anthrax. This ex¬ 
periment can be stopped after a week or two, as soon as a few shall 
have died, so as to save a useless loss of animals, the contagion 
being sufficiently proved by the death of a few. The Society 
will be at liberty to act on this last suggestion. 
9th. Twenty-five other sheep will be placed near the fenced 
spot, at some meters from it, in a place where no carbuncular
