56 57 MICROSCOPES.— Our natural eyes only e objects within certain limits in size, say, frc the point of a needle upward. But smaller ev than anything we can see with our eyes, there a world of things of wondrous beauty aud form, a thousand times more numerous than all ice do see, a world that everybody should see and can see. We have some glasses so arranged that we can see, examine, and measure insects so small that a common thimble will hold twice as mauy of them as there are inhabitants in all the world! And we can see their heads, eyes, bodies, etc. The glasses that enable us to see small things are called, MICROSCOPES. A common sun-glass, or read- ing-glass, gathers and brings extra rays of light to the eye and is really a simple Microscope. There are hundreds of forms and sizes. Then there are sets of several glasses or lenses put together so that they gather the rays, bring them inside and form an image there ; the eye looks in through a simple microscope, or eye-piece, which magnifies the imaije, and is thus able to see the thing looked at hundreds aud thousands and millions of times larger than the original object, according to the power of the instrument used. Such arrangements are called COMPOUND MICROSCOPES. These are of many forms and prices, from $10.00 for a pretty good one, up to thousands of dollars each. FINE OPEEA AND FIELD GLASSES, (Achromatic.)
