What kind of Information can a Compound microscope provide?

Much more information than I can type for the next three months. Blood cells, animal parts, leaf structures, snow flakes, and you get the idea. I was sick about two weeks when I was a child and we didn't know what was wrong. Finally we called the doctor, he didn't find anything either, so he took a blood sample, took it to his office, prepared slides, and announced I had malaria. He could see the parasites in the blood stream from the slides. A week of quinine and I was ok. How about that?

Thanks so much. Perfect.
