arrive at the conclusion that to the short list of true disinfec¬

THE SCIENTIFIC INVESTIGATIONS OF THE BUREAU OF 
ANIMAL INDUSTRY. 
By D. E. Salmon. 
(Continued from page 548.) 
We may also ask with much reason how Frosch can con¬ 
sider that Billings’ inoculations of hogs with a germ which 
the experimenter insists was not the hog cholera germ, and 
has no resemblance to it, nevertheless fill out the gaps and 
bridge over the doubts which he believes to exist on account 
of what he calls our objectionable methods in proving the 
pathogenic action of the hog cholera germ ? He certainly 
has no right to assume that because Billings sent him the hog 
cholera germ as his swine plague germ, in 1889, that this was 
the germ with which he worked previous to 1888, when Bil¬ 
lings expressly says so often in his report that it was not that 
germ. This is one of Frosch’s conclusions drawn from data 
other than that obtained from his bacteriological investiga¬ 
tions, and it shows how utterly unreliable he is when he leaves 
his own results and attempts to analyze and weigh reports of 
investigations written in the English language. For no one 
can suppose that inoculations with one germ would be of any 
value toward proving the pathogenic action of an entirely 
different organism. 
This is only one of the attempts which he has made to 
criticise the Bureau and endorse the work of Billings, in cases 
where an examination of the latter’s report does not sustain 
his language. For instance, he criticises the Bureau reports 
because the cultures used for inoculation were not derived 
from single colonies on gelatine plates, and yet he unhesitat¬ 
ingly accepts the inoculations of Billings as bridging over this 
gap, although we search in vain through Billings’ report for any
