A list of supernatural beings in the British Isles, from the Denham Tracts, 1892-5 (pictured).
~from The Penguin Book of English Folktales, Neil Philip, 1992The author notes that this is where Tolkien found the creature name: Hobbits. I also see Fire Drakes. And I’d add that since this was published, there are at least two recognizable creature/character names J.K. Rowling may have gotten from it.
