oedematous serosity at the periphery of the abscess, 

 when inocuhited in very small doses, transmits a 

 septicaemia, fatal in twenty-four hours, to successive 

 series of rabbits. 



The oedematous fluid and the blood contain, in 

 large numbers, ovoid microbes 0-8// to Ijx in length, 

 of which the extremities only take the color, so that, 

 after staining, it affects the form of an 8. 



The disease is easily transmissible by inoculation to 

 all species of birds ; according to Petri it may even 

 prevail as an epizootic in chickens, ducks and geese. 

 It is not transmitted to the guinea pig. 



In the rabbit it gives rise to the following lesions: 

 oedema at the point of inoculation, heiiiorrhagic 

 patches on the peritoneum and in the lung, and en- 

 largement of the spleen. Inoculated birds show a 

 rapid emaciation with lowering of the body tem- 

 perature; death, preceded by convulsions, arrives in 

 less than twenty-four hours. The alterations con- 

 sist in ecchymoses in the cellular tissue, abdominal 

 effusion, petechise upon the intestine, infiltration of 

 the lung, and the presence of a spumous mucus in 

 the bronchi. The blood of birds transferred again to 

 the rabbit in the smallest traces, reproduces the sep- 

 ticaemia in the latter. 



Spontaneous septiccBmias of the rabbit. 

 Lucet has described a disease of these animals 

 which prevailed in the hutches and occasioned serious 

 losses. The subjects show inappetence, emaciation, 

 torpor and temporary muscular spasms ; diarrhoea 

 also occasionally supervenes, and death always quickly 

 ensues. At the autopsy the blood is dark, the spleen
