Exercise So. Let the instructor, having placed upon the blackboard 

 the characteristics of some known microorganism, require of each student 

 the practice of identification of the bacterium from the data given, follow- 

 ing some selected analytic key; repeat with the characteristics of other 

 bacteria as desired.
