Observers of any of the sciences must have special preparation. For example, people who look through a microscopecan't see what's there unless their eyes are ready. It's not enough to have paperwork and know how to fill it in.Serious preparation is necessary. Henri Fabre gives a great description of his observations of insects, he describes his longand patient preparations forthese observations. He woke before the insects wake up,Didn’t smoke his pipe to be sure the smell of the smoke wouldn’t effect the insects. Knew a lot about the insects he was studding and prepared accordingly.
