Wonders of the Microscope.
A THOUSAND wonders in nature are lost to the human eye, and only revealed to us through the microscope. Think of dividing a single spider's web into a thousand strands, or counting the arteries and nerves in the wings of a gossamer moth. Yet, by the aid of the powerful lens of a microscope, it is found that there are more than four thousand muscles in a caterpillar. The eye of a drone contains fourteen thousand mirrors; and the body of every spider is furnished with four little lumps, pierced with tiny holes, from each of which issues a single thread, and when a thousand of these from each lump are joined together, they make the silk line of which the spider spins its web, and which we call a spider's thread. Spiders have been seen as small as a grain of sand, and these spin a thread so fine that it takes four thousand of them put together to equal in size a single hair.—Methodist Recorder.
