In The Island of Doctor Moreau , wanneer Prendick de Beast Man voor het eerst ziet, vertelt Montgomery hem dat het een "bogle" kan zijn:
I stood up in front of him. "What was that thing that came after me?" I asked.
He looked me squarely in the eyes, and twisted his mouth askew. His eyes, which had seemed animated a minute before, went dull. "From your account," said he, "I’m thinking it was a bogle."
I felt a gust of intense irritation, which passed as quickly as it came. I flung myself into the chair again, and pressed my hands on my forehead. The puma began once more.

Wat is dit "bogle" en waarom vertelde Montgomery aan Predick dat dit het was?
