One of those big bats that they call vampires had got at her in the night, and what with his gorge and the vein left open, there wasn’t enough blood in her to let her stand up, and I had to put a bullet through her as she lay.
– Bram Stoker
Dracula, Chapter 12. Quincey Morris tells the others how a mare that he was fond of was attacked by a vampire bat when he was on the Pampas.
