“ We looked, shivering, at the microscope, and the professor was gone. The chemist staggered over to the instrument, looked into it, and silently staggered back to his seat. On the screen in front of us the inhabitants of the drop of water lived and moved and had their being. Largest of all was the transparent jelly-fish, which was moving restlessly as though seeking a way of escape. The only sound in the room was the whir of the cinema and the harsh breathing of the chemist. ”
