SERUM AS A REMEDY FOR HOG CHOLERA.

throughout the world. I refer to the recent theory of Veteri¬ 
narian Schmidt of Holding, who claims that the cause of 
the disease is located in the udder, which by the sudden increase 
of lactation after birth loosens large masses of glandular cells or 
colostrum and these undergo a decomposition and form toxines 
and being absorbed into the circulation result in autointoxica¬ 
tion. Basing his therapy upon this theory,he directs his treatment 
to the udder and endeavors to lessen the abnormally high milk 
secietion. His treatment is said to be followed by the most 
gratifying results; 46 out of 50 cases so treated are said to have 
recovered. 
When I read the admirable article of Olof Schwarzkopf 
upon this new treatment which he read before the last meeting 
of the New York State Veterinary Society, I was struck by 
his remark : “ True, there are practitioners who believe they 
have found a ‘ sure cure,’ but sooner or later they will find, as 
we all have found, that at one time we may be quite lucky 
with a certain kind of treatment, while the second or third 
time we may be decidedly unlucky.” 
As you are all probably familiar with the article above 
mentioned and the details of the new treatment therein given, 
you will probably watch with much interest, as I am sure I 
shall, the results obtained from its use. Not having had an 
opportunity as yet to try the new treatment I am not in a 
position to criticise it or express an opinion as to its efficiency. 
SERUM AS A REMEDY FOR HOG CHOLERA. 
By J. D. Sprague, V. S., David City, Nebr. 
A Paper read before the Nebraska Veterinary Medical Association, February 21, 1899. 
Since the introduction of the use of blood serum as a thera¬ 
peutical agent, and particularly since Dr. A. T. Peters applied 
it in the treatment of hog cholera, stock raisers and veteri¬ 
narians have looked forward with much interest to the merits or 
demerits of the system. 
No doubt this is of much less interest to the city veteri-
