tion and dissemination of seed already sown. And this can only 
be overcome by true disinfectants and germicides—not substances 
that merely replace one foul odor with another still worse.

SECOND ANNOUNCEMENT OF THE WORK DONE AT THE EXPERIMENT STATION OF 
THE STATE UNIVERSITY OF NEBRASKA FOR THE STUDY OF 
CONTAGIOUS AND INFECTIOUS ANIMAL DISEASES. 
Lincoln, Neb., Jan. 22, 1887.—To the Board of Regents and 
the Chancellor of the University—Gentlemen: Herewith please 
find my second, and the most important announcement of the work 
done under your auspices. I think that you have no reason to be 
disappointed, as we only began working July last. While much 
remains to be done, in a strictly scientific sense, we need to make 
but one large test experiment in order to turn the question of 
the prevention of swine plague by inoculation over to the State 
authorities. I will not attempt to thank you for the constant 
trust and support you have given me, as well as your co-laborers 
of the board of regents, because I cannot, but will rather endeavor 
to show my gratitude by future work.
