The chapter opens with a lecture on the anatomy of birds by Professor Lin, who has just returned from a trip to China. The lecture is interrupted by the sound of a bird's cooing, and the narrator tells the audience that he will not spare Lin the next time he has the opportunity to kill a bird. He reminds the audience of the importance of the first step in science, which is to treat a living being as though it were a living thing.
