14 BULLETIN 65, U. S. DEPARTMENT OF AGRICULTURE. 
Dr. Munn, of Kearney, Nebr., had apparently good success from 
the use of diphtheria antitoxin as a prophylactic agent, since not a 
single animal developed the disease out of over 500 injected. It 
may be with this treatment, as with others, that good resuits 
were due to the fact that the disease was on the wane before treat- 
ment was commenced, but no other line of treatment gave as good 
apparent results. Dr. Kaupp also reports in the Breeders’ Gazette 
that only 1 horse died out of 960 inoculated with a diplo-strepto- 
coccic bacterin he prepared, but the injections were made so late in 
the outbreak that its value is still problematical, since thousands of 
horses in the affected area at this period failed to develop the disease, 
although they had received no preventive treatment whatsoever.
