Concerning a small insect, like a flea, which the natives call Attun.

THERE is a kind of bat94 in the country, bigger than the bats in Germany, and at nights these creatures fly about the huts and hammocks when the people are asleep. And when they see that anyone is asleep and not easily disturbed, they alight by the feet and bite off a mouthful, or they bite the forehead, and then they fly away.
