two objections to our inoculation experiments, first, that the: 
virus was not obtained from plate cultures, and, second, that 
the control animals in some cases died as soon, or even sooner, 
than the inoculated ones. This last objection should carry 
but little weight because, as pointed out by Smith, an inspec¬ 
tion of the records shows in every case where the controls! 
died at the same time, or earlier than the experimental ani¬ 
mals, that this was accounted for by the disease being of a! 
more acute type. 
When we analyze the report of Billings we find that 
what Frosch calls extensive and valuable experiments consist 
in 33 pigs all told which were inoculated, and two which were 
fed. Of the 33 inoculated at different times it is stated that 
two died, that three were killed for examination, and that 
“ the same general results occurred ” with six others as with 
one of those that were killed. The two that were fed died. 
There is not a particle of evidence that the virus used in any 
of these cases was obtained from plate cultures, and control 
animals did not complicate results for the very good reason 
that there were none in any of the experiments? 
It surely is not necessary for me to dwell at greater length, 
upon Frosch’s bias in Billings’ favor and the unaccountable 
conclusions to which this led him. But these are minor 
points which should not lead us to undervalue his contribu¬ 
tion to this subject when considered as a whole. The serious: 
thing to us is that it was these details in his statements — 
details based upon the flimsiest foundation, which attracted 
the attention of the Committee on Intelligence and Education, 
blinding the members to the real facts of value which were 
brought out by Frosch, and leading them to denounce in un¬ 
measured terms the investigations of the Bureau of Animal 
Industry and all individuals connected with them. 
It may be remarked here that no one can steal a discovery 
from another by objecting to the methods by which that dis¬ 
covery was made. Koch’s early investigations of the anthrax 
bacillus were made by methods which would certainly be 
considered very objectionable from the standpoint of to-day, : 
but his demonstration of the etiological relation of the bacillus
