nake a comparison, the hog-cholera germs should be ob- 
ained from the same source. 
The first thing that strikes one in staining such prepara- 
ions is that the swine-plague germ still shows its peculiar 
taining perfectly when kept in the coloring liquid a length 
)f time that would make the hog-cholera germ a uniform 
:olor throughout. Consequently, in staining the latter germ 
nore discretion must be used to obtain its typical appearance. 
The typical appearance is much more difficult to obtain with 
he organisms which have been grown in various culture media, 
s the tendency to produce a uniform color is much stronger, 
f, therefore, the germs sent to Billings by Detmers were coi¬ 
ned entirely, that is the proper and only possible indication 
hat the “tinction” had been too strongly applied. He goes 
o far as to admit, however, that “ sometimes there does seem 
3 be a very slight clear space in the middle of the body,’' 
ut he is careful to add that “ in no way does it resemble Mr. 
Salmon's description or plates.” It would have been inter¬ 
sting if he had pointed out how a clear space could exist in 
pe middle of a germ, and still not resemble in any way an¬ 
ther clear space located in the same position in another 
erm.

OPERATION FOR VENTRAL HERNIA.

The case I wish to report was that of a four-year-old mare 
I'ith a large rupture in the left lumbar region. I operated 
a November 4th, 1892, at St. Peters, C. B. My patient had
