HY PASTEUR’S VACCINE FAILS TO PREVENT HOG CHOLERA. 
By Dr. E. Salmon. 
[Extract from Breeders' Gazette.'] 
In the Gazette of March 18 is a paragraph headed “Inocula- 
*n for Hog Cholera a Failure,” which, though it appears anony- 
)usly, seems to have been inspired by some one connected with 
3 Nebraska experiments who was unduly anxious to make it ap- 
ar that these investigations had been conducted with the 
:rictest scientific accuracy,” and that some points of great im- 
rtance had been settled by them beyond controversy. I will 
iefly enumerate the claims which are referred to : First, the 
urn contained in the Pasteur vaccine is alleged to exist in large 
mbers in hogs that had died of American swine plague; second, 
.3 French rouget, for which Pasteur’s vaccine is prepared, is 
irefore identical with American swine plague; third, the Pas- 
u* vaccine failed to protect from American swine plague, conse- 
ently “Mr. Pasteur’s ‘inoculation theory’ has been tried and 
md wanting by the cold logic of facts.” 
The reader will no doubt agree with me that these are broad 
I I sweeping generalizations to be given to the world in such 
|| fitive language when the questions involved had only been 
ted by a single experiment. If so much science can be built 
so easily and in su short a time, surely some of those who have 
3 n working upon those problems for years with equally good 
•ilities must have sadly neglected their opportunities or must 
ve been lamentably weak in their perceptive faculties, or we 
>uld have known much more about hog cholera than has been
