vaccine called ''vaccine for revaccination" must be sent for; 

 The inoculation of the deuxieme vaccine is made 12 to 15 days 

 after that of the premier, 15 days being the extreme limit. 

 After this time the first vaccine is to be re-inoculated, as 

 the deuxieme would probably be too strong when inoculated 

 after this lapse of time. One-eighth c. c. is inoculated of 

 both the vaccines to small animals, and Jth c. c. to larger 

 animals. Elephants ought to have c. c. No treatment has to 

 be resorted to when oedema takes place at the point of 

 inoculation. How long the effect of vaccination lasts is 

 not certain, it is considered safe to vaccinate every year 

 60 per cent, of the animals vaccinated the previous year. 

 A flock already vaccinated, if it becomes accidentally subject 

 to anthrax, must be revaccinated at nee, if the mortality 

 breaks out within an interval of three months. After three 

 months complete vaccination, *. <?., a repetition of the premier 

 and the deuxieme vaccinations, must be resorted to. The 

 vaccine for revaccination is prepared in this way, in a 

 ballon pipette. A mixture is made of the first or premier 

 vaccine, recent and old (i.e., filamentous and sporular). 

 In another ballon pipette a mixture of the second or deuxieme 

 vaccine, recent and old, is made. The vaccine tubes for 

 despatch are filled half with the premier and half with the 

 deuxieme vaccines so mixed in the ballon pipettes. 



1,357. Even with all these precautions vaccination may 

 fail in certain cases, and it cannot be accounted for. The 

 processes are so many, and the opportunities of making 

 mistakes present themselves so often at each stage, that 

 it can be easily understood how difficult it is to explain how 

 some failures occur. 



!>358. When disease does not exist in a flock, but only 

 in this case, it is preferable to vaccinate the dams when they 

 are not pregnant, or only in the first stage of their pregnancy, 

 otherwise abortion may occur. It is necessary to vaccinate 

 lambs as soon as spontaneous disease is feared. Cows fall
