to demonstrate the presence of a specific micro-organism in this 
disease by means of isolation and cultivation experiments and 
animal experimentation. 
“ looked upon this organism as resembling, but not iden¬ 
tical with that of rabbit septicaemia, hen cholera and schweine- 
seuche.* 
“Kitt succeeded in inoculating pigeons and rabbits with this 
organism, but received negative results with guinea pigs, rats and 
hens. He calls attention to the regular appearance of a hcemor- 
rhagic tracheitis in rabbits on inoculation.” 
The investigations of Dr. Hueppe were made with blood 
sent to him, under every precaution, by Prof. Kitt. This blood 
was sowed upon gelatine plates, from the cultures of which 
numeious animals were inoculated j in other cases animals were 
directly inoculated with the blood, and after carrying it through a 
°eiies of animals pure cultivations of the micro-organism were 
also obtained. 
Xn both the exanthematous and pectoral form (Bollinger) a 
haemorrhagic entiritis was almost always present, as well as 
haemorrhages in different organs.f 
In the exanthematous form, which has a strong resemblance 
to carbuneular anthrax in cattle, there was observed a severe and 
extensive inflammatory oedema of the skin, which became hard as a 
board in from six to twelve hours, as well as oedema of the ex¬ 
ternally situated soft tissues of a more or less haemorrhagic char¬ 
acter. When the head was affected it became very much swollen 
and misshapen and the visible mucosae were cyanotic and the seat 
of numerous haemorrhagic infiltrations. 
Expeiindentation demonstrated that the natural eruption of 
the exanthematous form must be due to infection through acci¬ 
dental wounds in the skin of animals by the presence of the in- 
* As Kitt’s experiments were published in 1885, and as Schutz was the first 
to prove a specific bacterium in schweineseuche, though Lcefler had anticipated 
him somewhat, but without sufficient proof, and as neither Kitt or any one else 
had until then proven the pathologenic activity of the bacterium seen by Schutz 
in schweineseuche with certainty, I cannot see how Hueppe is justified in making 
the above assertion.—B.
