EDITORIAL. 
It seems that we were in error, for at the time when we 
were writing, the veterinary school of Dorpat (Russia), as 
our friend Prof. Schwartzkopff has informed us, was already 
carrying out the experiment we were speaking of. It was, 
however, evident that veterinarians, who could not help ob¬ 
serve the value and importance of the subject, would not re¬ 
main indifferent, and now we read in several of our exchanges 
reports of the organization of scientific works at the various 
schools of Europe, and also by some veterinary societies. 
America has not been backward in the movement, and the 
following, which we received some time ago from Prof. W. 
L. Zuill, speaks for itself : 
Organization of a Kooh Lymph Commission at the Veterinary Depart¬ 
ment of the University of Pennsylvania. 
The members of the Clinical Ptaff of the Veterinary Hospital of the Univer¬ 
sity of Pennsylvania held a meeting on Saturday, February 14th, for the pur¬ 
pose of organizing a commission to examine by careful and scientific investiga¬ 
tion into the value of Koch lymph in veterinary medicine. The commission 
intend to prosecute the study of this important question with the view of deter¬ 
mining its value in three special directions. First: To determine whether or 
not it is of any value to the veterinarian in diagnosing tuberculosis in cattle. 
Second: To discover, if possible, what may be its value as a curative agent. 
Third : To prove, by a series of carefully made experiments, if it be possible to 
give healthy animals immunity to the contagion of tuberculosis, and for what 
length of time. 
The Commission organized by the selection of Prof. W. L. Zuill, Chairman, 
and W. Edgar H. Landis, Secretary. The other members of the Commission 
are Prof. Simon J. Harger, Drs. Chalkley H. Magill, Charles Williams, Wm. 
H. Ridge, Robert Form ad and John Marshall. 
Milch cattle, supposed to be suffering from tuberculous, have been procured, 
and are being subjected to a most rigid examination to determine the presence 
of the disease. The temperature of these animals will be taken every two hours 
for at least twenty-four hours prior to the primary injection. The members of 
the Commission will make a careful physical examination of the animals, and 
will individually record the facts as they are clinically presented ; these records 
will be compared in making up the diagnosis. 
A bacteriological examination will also be made to determine the presence 
in the milk and bronchial mucous of the bacillus tuberculosis ; gelatine cultures 
will also be made from the milk and bronchial mucous, which should positively 
identify the bacilli if they be present. 
In this way the Commission expect to satisfy themselves that a given animal 
positively has tuberculosis. The lymph will be injected in comparatively large 
doses and the temperature and physical signs observed every hour during the
