of creolin, and doses of i J^ oz. of the same agent by the mouth. 

 Five buffaloes out of seventeen recovered. Friedberger suggests 

 deep incisions of the swellings so as to admit the air, and treat- 

 ment of the wounds with strong antiseptics. 



SUBACUTE AND- CHRONIC SEPTICEMIA HEMOR- 

 RHAGICA OF CATTI.E. 



Synonyms. Enteque, Entejado, Entecado, Pining, Pasteurellosis. 



Definition. A subacute or chronic affection of cattle (horse 

 and sheep) attributed to a Pasteurella and manifested by ner- 

 vous disorder marked hyperthermia and diarrhoea and in more 

 tardy cases by intermittent diarrhoea, advancing emaciation, 

 anaemia, debility and marasmus. 



History. Montfallet met with the affection in Chili, in 1896, 

 in cattle imported from Argentina, and I,ignieres in 1898, re- 

 corded its extensive prevalence in the Argentine Republic. It 

 should be looked for in the tropical and subtropical states of Amer- 

 ica and elsewhere. 



Bacteriology. I,ignieres found in the blood and affected tissues 

 a cocco-bacillus resembling that of fowl cholera, but shorter and 

 more slender, like the Pasteurella of influenza in the horse. This 

 stains slowly, best in gentian violet and fuchsin, coloring the 

 poles in the rounded ends, and leaving the median portion 

 without color, the recognized habit of the Pasteurella. It is 

 aerobic, growing best at 37" to 38° C. in neutral or feebly alkaline 

 peptonized or serum bouillon which it renders slightly turbid in 

 20 hours. Cultures in gelatine give in 3 or 4 hours colonies as 

 translucent bluish points, like millet seed. It does not coagulate 

 milk nor grow on potato. The microbe is found with difficulty 

 or not at all in chronic cases, the theory of I^ignieres and Nocard 

 being that the action of the Pasteurella is to enfeeble the tissues 

 by its toxins, so that they can no longer resist the attacks of other 

 microbes, and these accordingly are met with abundantly in the 

 chronic cases. The cocco-bacillus as the essential factor would 

 be more certain, if it persisted in the system throughout, or if 

 the later phenomena, in its absence were more evidently the pro- 

 duct of the secondary microbe, still present. Cattle die much
