My dear Leopold: 
From "Science" of the issue of October 4, 1929, 
I quote the following for your information: 
"Tularemia, newly discovered disease of rabbits, rodents, 
and men, may also affect cats, muskrats, pigeons, ring-necked 
pheasants, grouse and quail, it appears from studies reported to 
the American Public Health Aksociation by Dr. R. G. Green and 
E. M. Wade, of the University of Minnesota and the State Depart- 
ment of Health. This new disease which has caused much concern 
in public health circles, is acquired by men who handle infected 
animals. The fact that many more kinds of animals may have the 
disease greatly increases the danger to human beings by increas- 
ing the possible sources of infection."
