pie reason that no such germ exists in connection with swine 
plague as that described above.” (University of Nebraska, 
Second Report from the Patho-Biological Laboratory, 1888, 
3 . 54 -) 
Again he says“By thus ignoring them, he silently admits 
:hey were not ‘ un ’ but ‘ well-founded statements’ ; and hence 
as he has not, and cannot, prove them to have been, or be, 
erroneous, and those which he alludes to of 1885 are of the 
same nature, I emphatically declare that all Salmon’s asser¬ 
tions with regard to the specific microscopical appearances of 
my true and specific pathogenic micro-organism in connec¬ 
tion with hog cholera to be one continued series of ‘ unfounded 
statements’ down to the issue of his report of 1886.” (Loc. 
jcit. p. 68.) 
Once more he says: “I positively assert that Salmon’s 
assertion of a distinct germ for the disease which he now calls 
hog cholera is erroneous, and that the description of that 
object is a forgery ; that it does not exist or occur in any form 
of the American swine plague, and that neither Salmon nor 
any one else can demonstrate the presence of that object in 
the tissues or blood of any hog that has died of swine plague 
in any part of this country, if the examination is made before 
cadaveric changes have taken place. 
“ That the object described by Salmon as the germ of the 
hog cholera cannot be cultivated from the tissues of any ani¬ 
mal that has died of hog cholera or swine plague.” (L. c. 
P* 74 -) 
He returns to this subject as follows: 
“ That this substance does not represent a spore condition 
or have any relation to spores, is, to my mind, entirely beyond 
all question, as I have searched most diligently for spores in 
old and fresh cultures, and others made at all kinds of tem¬ 
peratures within the biological limits of these organisms, my 
search being inspired by the description of what I pronounce 
a forgery, of a germ (which represents a spore), as the cause 
of swine plague, by My. Salmon in 1885, and again in 1886, 
as the cause of an assfimed porcine pest, to which Mr. Sal¬ 
mon now gives the name of ‘ hog cholera,’ 1 his Salmon ob-
