approximates closely to the hog cholera germ in morphology 

 and motility and in its deadly action when eaten, while it ap- 

 proaches toward the swine plague germ in its cultural habits on 

 potato, gelatine and agar, and in alkaline culture liquids, and 

 finally it differs from both in the absence of pathogenesis to 

 Guinea pigs and in its very moderate action on rabbits. The 

 symptoms and lesions of the swine fever of Great Britain are 

 those of the hog cholera of America rather than of swine plague. 



Marseilles Swine Plague Bacillus. This microbe was 

 found by Rietsch and Jobert in a febrile epizootic of swine at 

 Marseilles, and was studied by Caneva and Bunzl-Federn sepa- 

 rately. The latter identified it with the bacillus of ferret septi- 

 caemia, as described by Eberth and Schimmelbusch. It was 

 longer and thicker than the hog cholera bacillus, twice as long 

 as broad, actively motile, with flagella, and differed from bacillus 

 cholerae suis, in its polar staining, its free growth in acid media, 

 in acidifying and coagulating milk, and in its forming both indol 

 and phenol in peptonized bouillon. 



In this case the source of the disease was in importations from 

 Africa (Fouquet), and it spread widely in Southern France for 

 nine months. It proved almost constantly fatal, in from four 

 days to two or three weeks. The symptoms were weakness 

 especially in the hind limbs, with more or less fever, constipation 

 often followed by diarrhoea, an infrequent cough, and red blotches 

 on the skin. In chronic cases ulcers formed in the mouth and 

 intestines especially the caecum and colon. Appetite was often 

 retained to the end. The young, under a year old, were the 

 chief sufferers. It made 20,000 victims in several months in the 

 province of Bouches-du-Rhone.
