SERUM AS A REMEDY FOR HOG CHOLERA. 
your bill and looks pleasant, but it also raises you in his esti- 
mation and likewise convinces him of the fact that the men fol 
lowing the profession are worthy of the name. 
And while there may be but little or no financial returns 
irect y in the treatment of the hogs, yet I am quite sure that 
most any country practitioner can well afford to treat the lioo-s 
as well as the other animals. ° 
It is not my intention to theorize upon the curative prop¬ 
erties of hog cholera antitoxin from a scientific standpoint, that 
is, whether or not its action is due to ptomaines, leucomaines or 
o some peculiar action of the phagocytes ; or what action it 
has upon the blood of the animal treated, to render it immune. 
or bacteriologists alone are capable of dealing with such ques¬ 
tions and they know little enough about this particular one 
But what interests us most is, will the use of serum in 
hog cholera be practical ? And what little I say along this line 
will be from observations made in the use of it during the last 
two years. I will roughly review my use of it in the different 
herds:

tion and remained so, but as we never knew of their beino- ex¬ 
posed to the infection it furnished no evidence of the efficiency 
of the remedy. 
Lot II. 20 head free from the disease at the time of treat¬ 
ment were placed in infected pens. All remained well for two 
months, when one died after a few days illness. 
. Lot IIL 3 ° head healthy hogs treated and in ten days placed 
in pens where owner had lost all of his hogs three months prior 
All remained healthy. 
Lot IV. Badly infected herd of 80 head ; treated 40 and 
separated them from the balance of the herd ; 10 of the treated 
and 25 of those not treated died. 
Lot V. 45 head of pigs generally infected, but unknown to 
■ e owner, were placed in pens with 55 healthy hogs. In 5 days 
2 ot the 45 head died and most of the others with 2 of the 55 head 
showed plainly symptoms of cholera. These were removed to
