The first page had a drawing of a pony with all the parts clearly labeled. It looked exactly like the drawing he and Lyra had gone over on the beach, when she'd been identifying the parts on her own body. That had been right about when he figured out that she wasn't wearing a spacesuit. He turned the page, took one look at the drawings, and slammed the book back shut. I don't think I'll need to add those words to my vocabulary anytime soon.
