Mice and birds ai'e very susceptible; guinea-pigs and white rats have an immunity. DaVAINe's SEPTICiEMIA. A disease was produced by Davaine by injecting rabbits with putrid blood. Rabbits, mice, fowls, pigeons, and .sparrows are sus- ceptible, and guinea-pigs and rats are insusceptible to the bacteria found in this disease. Rabbits inoculated with a trace of blood con- taining the bacteria, or' with a culture, died in from twenty-four to thirty-six hours. The spleen, liver, lungs, and intestines are highly congested, and sometimes extravasations and peritonitis are found. Fowl Cholera. Fowl cholera is an epidemic disease of the poultry-yard much dreaded in France, and well known through the researches of Perroneito, Toussaint, Pasteur, and Eatt.
