The first of the breeding rabbits to die were examined by 
Dr. Kilborne who found extensive pleuritis. Subsequently the 
dead animals were brought to the laboratory where they were 
carefully examined. As soon as the seriousness of the disease 
was realized all of the rabbits were inspected and those sus¬ 
pected* of having the disease were removed, and the pens thor¬ 
oughly disinfected. By repeating the disinfection after each 
death and removing immediately all suspected rabbits the out¬ 
break was abated, but not until after many deaths had oc¬ 
curred. About one-third of the rabbits that were affected 
with the rhinitis died in a short time and a few of those that 
were isolated perished in the course of several weeks. 
♦The only evidence of disease that could be found among the living animals 
was a mild or more severe rhinitis, and it was by that symptom that the rabbits 
were separated.
