killing of all the animals of small herds in which the disease has 
freshly broken out in a district which had previously been free 
from the same. In large industrial establishments, where cattle 
are kept, it is possible that the exact execution of such a regula¬ 
tion would be met with economical considerations of such import 
to the agricultural condition of the district, as to render the same 
unjustifiable. Therefore, it is so much the more our duty to 
TEST IN THE MOST EXACT MANNER THE VALUE OF INOCULATION. 
Wellenbergh, director of the Veterinary School at Utrecht in 
1852, says: “ Shall it really result that the receptivity for the in¬ 
fectious stuff of pleuro-pneumonia can be rendered null by means 
of inoculation, for which some authors contend, but which can 
only be conceded when the animals are again exposed to infec¬ 
tion after the inoculation and its results have entirely disappeared, 
then we must look upon this discovery as one of the most im¬ 
portant in the interest of veterinary science.” 
Since then inoculation with reference to pleuro-pneumonia has 
been practised in many lands, and found many enthusiastic de¬ 
fenders amoug veterinarians and agriculturists. In the 3d. report 
of the Holland Commission—1855—consisting of the Instruction 
Collegium of the Utrecht School—Wellenbergh, Jennes, Heck- 
meyer, Van Laer, Witt, and Hengeneld, it is said that the inocu¬ 
lation of Willems, correspondingly and circumspectly employed, 
has no equal in veterinary medicine. Opposition to inoculation 
is not wanting, however, but mostly from persons wanting in 
actual experience in the inoculation question. Tn Saxony, where 
the disease has constantly prevailed for a succession of years, all 
cattle owners who have become acquainted with inoculation 
through actual experience, are almost unanimously of the opinion 
that the same is capable of rendering good service in reference 
to shortening the course of, or the stamping out of, pleuro-pneu¬ 
monia, if timely resorted to and executed in a conformable man¬ 
ner. In my opinion, it would be a great error to pass over with 
silence or neglect the experience of enlightened owners or breed¬ 
ers. Herr Kimpau, a very intelligent and experienced agricul¬ 
turist, read an extensive paper with regard to this question, from 
which I make the following quotations (found in full in Zeitschrift
