SMALL MATTERS.--The nerve of a tooth, not as large as the finest cambric needle, will sometimes drive a strong man to distraction. A musqueto can make an elephant absolutely mad. The coral rock, causing a navy to founder, is the work of worms. The warrior that withstood death in a thousand forms may be killed by an insect. The deepest wretchedness results from a perpetual continuance of petty trials. A chance look from those we love, often produces exquisite pain or unalloyed pleasure. * * * * * “Take your _time_,” as the man said, when he returned a borrowed watch. [Illustration: bat] The Bat Family. The family of bats is very numerous, and some of its members are queer characters, as we shall presently show. They have puzzled the naturalists not a little; for while they have the structure of quadrupeds, they have the motion of birds. They are the only creatures that unite these two qualities. There are such things, indeed, as flying squirrels, and flying opossums, but these do not raise themselves by wings; they only support their bodies by spreading out skinny membranes on either side, in descending from an elevation, and are thus able to make a long, sloping leap. The bat, on the contrary, raises himself into the air by his wings, and glances about hither and thither, with all the ease and vivacity of a bird. Yet this creature has no feathers. He is covered with hair, and when his skinny wings are folded up, he looks very much like a mouse or a mole. He even squeaks like a mouse, and thus an appearance of veracity is given to the fable of La Fontaine. In this, the bat is represented as having, on a certain occasion, got into the nest of a weasel, the sworn enemy of birds. When the weasel was about to destroy him as one of the feathered tribe, the little fellow escaped by representing himself to be a mouse. Afterwards, coming in the way of the cat, he was upon the point of being devoured as a mouse; but he now showed his wings, and was let off, on the plea of being a bird. In a former number, we have spoken of the vampire, which is found in Guiana, and have made mention, also, of certain other species of this curious tribe. We now proceed to speak of the general habits of the whole race. They frequent caverns, dark ravines, and crevices of rocks. Here they sleep by day, but, as evening approaches, they sally forth, pursuing such insects as have not gone to their repose. They are active and busy during the warm season, but when the cold evenings of autumn set in, they retire to their dim retreats, where they often cluster together by hundreds. Here they remain in a dormant state during the winter. In this condition they show the greatest sensibility to the touch, and their bodies even shrink from the approach of the hand, before it comes in contact with the body. Yet nothing can rouse them from their profound sleep.
