— M. Pasteur has shown that the bacillus of “ rouget,” as 
found in pigs, can be attenuated by passing it through rabbits. 
The inoculated rabbits are all rendered very ill or die, but pigs 
inoculated with the bacillus, after the virus has been passed 
through a series of rabbits, have “ rouget” ina mild form, and 
enjoy immunity from further attacks. A series of inoculations 
carried through pigeons, on the other hand, increases the viru- 
lence of the disease when a pig is inoculated from the last of the 
pigeons. .
