These sundry observations attest, in a convincing man- 

 ner, that the German veterinarians do not consider the 

 bovine family refractory to gaseous gangrene. Just re- 

 cently, in fact, Koninski drew the following conclusions 

 from similar observations : 



1. The spontaneous evolution of malignant oedema in 

 bovidse can be considered as well proven. 



2. In certain cases malignant oedema can become en- 

 zootic and may present forcible resemblance to sympto- 

 matic authrax. 



3. As is the case with anthrax, .enzootic malignant 

 oedema appears to reign above all in low lands. 



4. The clinical symptoms, the same as in the enzootic 

 character, do not permit of a positive differential diagnosis 

 from anthrax. In either case it is necessary to make a 

 microscopic examination of serum taken from the oedema, 

 in lieu of a recourse to experimental inoculations. 



5. If one considers the endemic faculty of malignant 

 oedema, the clinical characteristics common to this affection 

 and symptomatic anthrax and that the micro-organisms of 

 both diseases resemble each other, it is easy to conclude 

 that both germs have a common origin, or at least a close 

 relation. Aside from the preceding observations which 

 compel the deduction that gangrenous septicaemia is an al- 

 lied disease, note the observations of Strebel, who saw a 

 cow die following blood-letting from the coccygeal vessels. 

 The lower part of the tail was gangrenous and infiltrated 

 with gas. The tail was amputated, but in spite of complete
