diseases present perfect similarities. For those reasons the two 
pathogenous agents, in bacterian classification, have been 
brought together and even sometimes identified. The investi¬ 
gations of Roux and Cliamberland, of Kitasato and Duensch- 
mann show the interest in the comparative study of these two 
germs, and recently the subject has been taken up again by 
two well-known authorities—Profs. Leclainclie and Vallee, of 
the Veterinary School of Toulouse. Their researches upon 
symptomatic anthrax have brought them to study the rela¬ 
tions of both germs to the double point of view of the special 
properties of each and of the immunity against the diseases they 
give rise to. It is in that way that they were called to consider 
their morphology, the various methods of immunization by vac¬ 
cine viruses with toxines, and the use of serotherapy, which 
demonstrated to them that to that point of view, septic vibrio 
and B. Chauvosi proceed in an identical manner. The effects 
upon the agglutination upon the cultures have also received 
their attention. The conclusions advanced by these authors 
are that : 
(1) There exists between the bacteria of symptomatic an 
thrax and the septic vibrio, biological relations which are very 
close. However, it is possible to differentiate them : the septic 
vibrio gives, in the serosity of the specific oedema and in the 
peritoneum of cobaye, long threads which are regularly missing 
in symptomatic anthrax. 
(2) Immunization against septic vibrio can be extended to 
all the methods which are applied to symptomatic anthrax. 
(3) Immunizing serums against anthrax and gangrenous 
septicaemia ha've a strictly specific action. The observations 
made on the agglutination with the same serums, is also spe¬ 
cific. 
(4) In relation to anthrax, immunization does not imply 
resistance.to the septic vibrio, and reciprocally animals vacci¬ 
nated against septicaemia are not against symptomatic anthrax. 
Those experiments have a great bacteriological value, 
throw an important light on the subject, and are valuable addi-
