CHAPTER VII. 



On Microscopical Drawing and Painting. 



A GREAT teacher has said " Drawing should be 

 considered not an accomplishment, but a necessity. 

 Learning to draw is learning the grammar of a 

 language. Anybody can learn the grammar, but 

 whether you have anything to say is another 

 matter." To the naturalist this accomplishment is 

 of great importance ; accurate illustration adds to 

 the value of written description. At every point 

 the microscopist is sensible of its deeper signi- 

 ficance. Such a control quickens the perception, 

 excites exact observation, and creates an interest 

 beyond research, admiration, or curiosity. The
