killed the pigs fed ou them with typical swiue fever ; aud this 
result followed when the rpiantity of virus used was exceed- 
ingly small. 
It is proposed to continue the search for a protective agent 
against swine fever ; and in the next series of experiments 
certain chemical agents will be used instead of diluted or culti- 
vated virus. 
It is also proposed to make pure cultivations of all the organ- 
isms which are found in swine fever, in order to ascertain if any 
of them will cause the actual disease in swine with all its typical 
characters. 
Anthrax in Swine. 
It is well known that pigs which eat the ofl'al of aninuils 
dead of anthrax die from a disease which veterinary surgeons 
in this country have alwa^'S been in the ha.bit of calling anthrax. 
On the other hand, scientists have failed in Glermany, and aho 
in this country, to induce the disease in swine by inoculation 
with the blood of animals which have succumbed to the disease. 
In these circumstances it was deemed advisable to test the 
susceptibility of swine by feeding them with the diseased parts. 
A s})leen of an ox which had 
died of anthrax was given to 
two pigs, and the animals 
soon developed the usual 
symptoms of illness ; a 
very marked condition being 
swelling of the throat, as 
shown in the illustration (Fig. 
G, page 325). 
In the cases of so-called 
anthrax in swine which were 
investigated, the bacillus 
wliich is ])roper to the disease 
Avas not detected, but, instead, 
a long curved rod, the bacillus 
of malignant oedema ; and

ported by Mr. Wilson, veterinary surgeon of Eerkhampstead ; 
and Dr. Crookshank, on a post-mortem examination, detected 
the anthrax organism in the Ijlood of the spleen ; but it was
