diseases. But I am not inclined to attach any great importance to these 

 differences as set forth in the reports. The descriptions otherwise I 

 find correct and well stated. In my investigations as commissioner I 

 have been able to find but one organism which, in my opinion, caused 

 the outbreaks under examination, and that I regard as identical with 

 the hog-cholera germ described in the reports of the Bureau, and I find 

 the description therein given correct. As will be inferred from what 

 has gone before, I feel sure that another organism, correctly described 

 in the reports as the " swine-plague germ," is found under circum- 

 stances which render it highly probable, if not certain, that it also 

 causes disease. 



As to whether these two organisms are always present and operate 

 together to cause disease, or whether the two are merely varieties of 

 the same germ, must be decided by future investigation. The differ- 

 ences between them, as pointed, out by the Bureau, are sufficient to 

 compel us to treat thorn as different germs, however perplexing it may 

 seem that two micro-organisms are capable of producing such similar 

 or, it may be, identical lesions. 



By subcutaneous inoculations of the germ which I obtained from 

 Nebraska, South Carolina, Washington, and Baltimore I failed to pro- 

 duce the disease by subcutaneous inoculations of even 5 cubic centi- 

 meters of bouillon cultures and more in hogs. I have, however, suc- 

 ceeded in producing it, though not every time, by feeding fasting 

 animals (hogs) with bouillon culture. 



(2) I have not been able to find that the descriptions of the germs 

 contained in the above-mentioned reports from the Bureau have been 

 antedated by other correct descriptions. Indeed, the bacteriological 

 methods previous to the appearance of these reports were not nearly as 

 accurate as those described in the latter, and consequently the value of 

 the earlier observations is proportionally less. It is only by the correct 

 application of Koch's methods that trustworthy results can be obtained, 

 and it does not appear that these methods are employed in any investi- 

 gations previous to the Bureau reports. 



(3) The disease which has been investigated by Drs. Billings and 

 Koberts in Nebraska I take to be identical with the hog cholera de- 

 scribed by the Bureau. In the cultures I obtained from material in 

 Nebraska I only found hog cholera as described in the Bureau reports, 

 and the description of the organisms of the above-named gentlemen 

 tallies more nearly with the description of hog cholera than with the 

 description of swine plague contained in the reports of the Bureau. I 

 do not see that any important facts have been established by any one 

 which differ materially from the conclusions given in the reports of the 

 Bureau of Animal Industry. The answers to the other questions in 

 this paragraph are implied in what has already been said. 



(4) My opinion in regard to the bacterism of swine plague as described 

 in the reports I have already given under paragraph 1. What was re-
