In the interior, a large species of very poisonous bats is common, and their gaze have a hypnotic effect even worse than a rattlesnake, so that someone who has caught the eye of such a bat, is soon as if drugged by a strong drink, falls to the ground, and if no one comes to his aid and kills the fluttering bat, it sucks the last drop of blood from him and then flies away sated and whistling sharply. – The Twelve Hours, Chapter 7, Paragraph 28
