Let it not be supposed, however, that these queer facial appendages and long ears of the leaf-nosed bats are purely ornamental. Dr. George E. Dobson, one of the greatest authorities on bats, has pointed out two very curious facts. (1) The bats with small ears and no nose-leaves fly most in the early twilight; and many, such as the fruit-bats, fly in the day- time. (2) The long-eared and leaf- nosed bats prefer darkness, and seek their food only at night. Let us see if we can find a reason for this. A cruel investigator of the eight- eenth century, named Spallanzani, once destroyed the eyesight of several bats, then suspended many silken threads from the ceiling of a room and liberated the creatures. Although totally blind, the bats flew to and fro between the threads, without once striking them, and were equally successful in avoiding branches of trees that were introduced. It now seems certain that some bats possess a sixth sense, of which at present we know nothing, by which they are able to fly in total darkness, and avoid even the smallest obstructions.
