what discovery does jonathan make about the count in the count's room ?

Jonathan discovers that the Count is actually a girl. No, I'm just kidding! In chapter three he sees expensive furniture, rich tapestries and fabrics, and a library filled with reading material in English. I think the most interesting thing he notices is that there are no mirrors to be found anywhere. In Chapter 4 he discovers a heap of gold. Discovering a dark, winding stairway, Harker follows it and encounters fifty boxes of earth in a tunnel-like passage. Harker opens several of the boxes and discovers the count in one of them, either dead or asleep. Terrified, Harker flees back to his room.
