There is a wonderful study conducted in 1898 by von Bortkiewicz which provides data on the
death of soldiers in the Prussian army from kicks by horses and mules. The data pertain to 10
army corps, each observed over 20 years, for a total of 200 corps-years. The following table
summarizes the observed data: note that in 109 corps-years zero deaths occurred; 65 corps-years
had one death, etc.:
