and cannot be killed with anthrax, at least for a certain time 
whose length is now determined to he from 18 to 20 months. 
This being established, and in order to avoid giving the animals 
a disease which might prove fatal for some, two protective inocu¬ 
lations are made. The first is with a very attenuated bacteridie, 
the first vaccine, which give to the animal only a very slight fever, 
characterised by a rise in the temperature; the second, made 
twelve or fifteen days later, with a more virulent bacteridie. It is 
the second vaccine which would kill a certain number of animals, 
were they not already partially protected by the preceding vac¬ 
cination. But this partial protection exempts them from all in¬ 
fection beyond a slight fever, and when relieved of this the ani¬ 
mals are perfectly vaccinated, and have become entirely refractory 
to the disease. 
The liquids of inoculation are delivered in closed tubes, and 
are introduced with' the syringe of Pravaz. The first inoculation 
is made on the inside of one leg in sheep, and on one side of the 
neck or of any part of the body where the skin is thin in other 
animals; the second being introduced on the opposite leg or side. 
The rod of the syringe is divided into a given number of parts. 
For sheep the quantity to be injected is indicated by each one of 
these divisions, the dose for the large animals being double. In 
this way one will see that a syringe full which may serve to 
operate on eight small, will serve but four large animals. It is 
of the greatest importance that the instrument should be per¬ 
fectly clean, and for this reason it is better when not a new one, 
and when it has already been used, to have it thoroughly 
cleansed and heated whenever a new operation is to be performed. 
I present you with some of these tubes, which I have had re¬ 
cently imported for this occasion. I understand the liquid has to 
receive a special preparation when exported from Europe. It 
will, no doubt, be very interesting to all to see the trial made, and 
the result made known. 
This is the process of vaccination for anthrax proper—splenic 
apoplexy. But as this disease differs entirely from rymptomatic 
anthrax, gloss anthrax, black leg, etc., etc., the process which pro¬ 
tects from the attack of the first disease will be without result
